Answer:
see explanation
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
First obtain the equations in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
(1)
calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, 2 ) and (x₂, y₂ ) = (3, 4 )
m = [tex]\frac{4-2}{3-1}[/tex] = [tex]\frac{2}{2}[/tex] = 1 , then
y = x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (3, 4 ) , then
4 = 3 + c ⇒ c = 4 - 3 = 1
y = x + 1 ( subtract y from both sides )
0 = x - y + 1 ( subtract 1 from both sides
- 1 = x - y , that is
x - y = - 1 ← in standard form
Use the same procedure for the next 2 questions
(2)
(x₁, y₁ ) = (2, 5 ) and (x₂, y₂ ) = (3, 7 )
m = [tex]\frac{7-5}{3-2}[/tex] = [tex]\frac{2}{1}[/tex] = 2 , then
y = 2x + c ← is the partial equation
using the point (2, 5 ) to find c
5 = 2(2) + c = 4 + c ( subtract 4 from both sides )
1 = c
y = 2x + 1 ( subtract y from both sides )
0 = 2x - y + 1 ( subtract 1 from both sides )
- 1 = 2x - y , that is
2x - y = - 1 ← in standard form
(3)
(x₁, y₁ ) = (5, 2 ) and (x₂, y₂ ) = (3, 12 )
m = [tex]\frac{12-2}{3-5}[/tex] = [tex]\frac{10}{-2}[/tex] = - 5 , then
y = - 5x + c
using the point (5, 2 ) to find c
2 = - 5(5) + c = - 25 + c ( add 25 to both sides )
27 = c
y = - 5x + 27 ( add 5x to both sides )
5x + y = 27 ← in standard form

Your neighbor pays you $17 for every two hours of work how many hours do you work if you earn $42.50
Answers
Answer:
To find the number of hours you work, you need to set up an equation using the information given. Let's say that the number of hours you work is x. The equation would be:
17(x/2) = 42.50
The parentheses around x/2 indicate that the division should be done before the multiplication. So, x/2 = 2.5. Multiplying both sides of the equation by 2 gives us:
x = 5
So, you work 5 hours.
Step-by-step explanation:
So, we know that you earn $17 per 2 hours. We also know that we earned $42.50. Now, we just need to find the hours! We can do this by using a cross multiply.
$17 is directly correlated to 2 hours of work. Therefore, to find the hourly wage we should divide it by 2:
$8.5 = 1 hour
$42.50 = x hours?
Now cross multiply:
$8.5x = $42.50
x = 5 hours
Therefore, your answer is 5 hours!
Hope this helps!
Is a log graph increasing or decreasing?
Answers
A log graph can be either increasing or decreasing, depending on the function or data being graphed.
A log graph is a type of graph that displays the data on a logarithmic scale. That is, the values of the data are represented on a logarithmic scale, rather than on a linear scale. This type of graph is useful for displaying data or functions that span a wide range of values over a large range of exponents. The direction of the graph depends on the data being graphed or the function being shown. If the values of the data or the function being graphed increase over time, then the graph will be increasing. Conversely, if the values of the data or the function being graphed decrease over time, then the graph will be decreasing.

Which two ratios form a proportion?
Responses
A 12/15 and 5/4
B 15/12 and 5/4
C 6/5 and 4/5
D 5/6 and 4/5
Answers
Answer:
Step-by-step explanation: We will determine if ratios are proportional using cross multiplication.
first, we will check option (a)
12/15 =5/4
12*4 = 15*5
48 is not equal to 75. So, these are not proportional.
now, we will check option (b)
15/12 = 5/4
15*4 = 12*5
60 = 60.
as the left-hand side is equal to the right-hand side.
So, option (b) is correct.
Answer:
[tex]\textsf{B)} \quad \dfrac{15}{12}\; \textsf{and}\;\dfrac{5}{4}[/tex]
Step-by-step explanation:
If two fractions are equal, they form a proportion.
Therefore, to determine if two ratios form a proportion, rewrite the fractions so that their denominators are the same, then compare.
[tex]\textsf{A)}\quad \dfrac{12}{15}\; \textsf{and}\;\dfrac{5}{4} \implies \dfrac{12 \times 4}{15\times 4}\; \textsf{and}\;\dfrac{5\times 15}{4\times 15}\implies \dfrac{48}{60}\; \textsf{and}\;\dfrac{75}{60}[/tex]
As the two fractions are not equal, they do not form a proportion.
[tex]\textsf{B)} \quad \dfrac{15}{12}\; \textsf{and}\;\dfrac{5}{4}\implies \dfrac{15}{12}\; \textsf{and}\;\dfrac{5 \times 3}{4 \times 3}\implies \dfrac{15}{12}\; \textsf{and}\;\dfrac{15}{12}[/tex]
As the two fractions are equal, they form a proportion.
[tex]\textsf{C)} \quad \dfrac{6}{5}\; \textsf{and}\;\dfrac{4}{5}[/tex]
The denominators of these two fractions are already the same.
Therefore, as the two fractions are not equal, they do not form a proportion.
[tex]\textsf{D)} \quad \dfrac{5}{6} \; \textsf{and}\;\dfrac{4}{5}\implies \dfrac{5\times 5}{6\times 5} \; \textsf{and}\; \dfrac{4\times 6}{5\times 6}\implies \dfrac{25}{30}\; \textsf{and}\;\dfrac{24}{30}[/tex]
As the two fractions are not equal, they do not form a proportion.
There i a bag filled with 4 blue, 3 red and 5 green marble. A marble i taken at random from the bag, the colour i noted and then it i replaced. Another marble i taken at random. What i the probability of getting 2 blue?
Answers
The probability of getting 2 blue is 1/9.
You are choosing replacement marbles. The trials (marble selections) are independent from one another and follow the binomial distribution.
1/3 of the time, a blue marble will be the first one chosen.
(This is due to the fact that 4 out of 12 marbles are blue, therefore 4/12 equals 1/3.
A blue marble is 1/3 more likely to be chosen the second time.
The two probabilities can be multiplied to obtain the following results because the marble selections are independent:
The likelihood of receiving two blues is (1/3)2 =1/9.
Therefore, there is a 1/9 chance of obtaining two blues.
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

AAA triangles are impossible to solve further since there is nothing to show us the size.
The AAA triangle is a triangle in which all three angles are given, and the triangle is said to be similar to another triangle if any two of its three angles are equal to any two of its three angles.

There are four shortcuts that can be used to check whether two triangles are congruent.
You don't need to be familiar with all of the six corresponding parts, which include three angles and three sides.
When a triangle's three angles are known but not its sides, the answer is "AAA."

What is compound interest?Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.
It occurs when interest is reinvested, or added to the loaned capital rather than paid out, or when the borrower is required to pay it, so that interest is generated the next period on the principal amount plus any accumulated interest.
In finance and economics, compound interest is common.
In contrast to simple interest, which does not compound since past interest is not added to the principal for the current period, compound interest allows interest to build over time.
The interest per period multiplied by the number of periods in a year yields the simple annual interest rate.
According to our question-
Last year, a part-time housekeeper earned $8798.
He claimed he was exempt, costing $365.

There are 6 grandkids.There are two girls.Out of the six grandchildren, two are to be chosen.
There are 6C2 different ways to choose 2 out of 6 grandchildren.
6C2 = 6! / (6 - 2)!*2!
6C2 = 15
There are 15 different ways to choose two grandchildren out of six.There are 2C1 different ways to choose 1 of the 2 girls.
2C1 = 2
There are two different ways to choose one of the two girls.
Number of methods for choosing both girls = 2C2
Number of methods for choosing both girls equals one.
Probability of choosing 1 of the 2 grandchildren is 1/15.
The likelihood of choosing both girls is 2/15.
Probability that one of the females (Piper and Sedona) will be able to attend the performance is:
= 1/15 + 2/15.
= 3/15.
Thus, Probability that atleast one of girls (Piper as well as Sedona) will be able to attend the performance is one in five.

Perimeter > 50 solve please need by tonight
Answers
Answer:
Step-by-step explanation:
x + 4 + 2x - 6 + 10 > 50
4 - 6 + 10 = 8
x + 2x = 3x
3x + 8 > 50
Subtract 8 from both sides
3x > 50 - 8
3x > 42
Divide 3 from both sides
42/3 = 14
x > 14
What is the midpoint of 1 and 2 and 3 and 4?

The height of the tree to the nearest hundredth of metres is 2.03 metres.
How to find the height of a tree?Emily is 1.65 metres tall. At 3 pm she measure the length of a tree's shadow to be 28.15 metres . She stands 22.9 metres away from the tree, so that the tip of her shadow meet the tip of the tree shadow.
Therefore, the height of the tree to the nearest hundredth of metres can be calculated as follows:
using proportion,
let
x = height of the tree
Therefore,
1.65 / 22.9 = x / 28.15
cross multiply
28.15 × 1.65 = 22.9 × x
22.9x = 46.4475
divide both sides by 22.9
x = 46.4475 / 22.9
x = 2.02827510917
x = 2.03 metres
Therefore,
height of tree = 2.03 metres

Mr. Nunez brought 2 1/2 cake to chool for her cla. If there are 15 people in the cla ,including Mr. Nine, how much of the cake will each peron receive
Answers
Each person present in Mrs. Nunez's class is going to receive 1/6th part of the cake when they get it cut.
Mr. Nunez brought 2 ½ cakes for 15 people which means, 2 ½ cakes will be equally divided into 15 pieces and distributed to each person. Since 2 ½ is a mixed fraction we have to convert it into a regular fraction which will be equal to 5/2. So, the amount of cake a person will receive is equal to (5/2)/15 which is 1/6, which is roughly 0.167 part of the whole cake.
The given problem has been solved by using the properties of fractions.
