Which graph correctly represents 3x + y > 7?
NEED HELP!!
The graph of the inequality: 3x + y > 7
Can be seen in the image below.
Which graph correctly represents the inequality?We want to see which graph represents the inequality:
3x + y > 7
We can rewrite the inequality in slope-intercept form as:
y > -3x + 7
So we just need to graph the line:
y = -3x + 7
With a dashed line, and then shade all the region above the line.
To graph the line, you need to find two points that lie on the line.
if we evaluate the line in x = 0 we wll get:
y = -3*0 + 7
y = 7
if x = 1
y = -3*1 + 7
y = -4
Then we have the points (0, -7) and (1, -4), now we can graph these two points and connect them with a dashed line, then shade the region above.
The graph of the inequality is the one below.

For the given equation of the line 2x + 3y = 6 , the slope = -2 /3,
the x-intercept = 3 and the y-intercept = 2.
As given in the question,
Given equation of the line is :
2x + 3y = 6
Standard equation of the line with slope 'm' and y -intercept = c
y = mx + c
Convert the given equation into standard form we get,
2x + 3y = 6
⇒ y = (-2/3)x + 6/3
⇒y = (-2/3)x + 2
Slope of the line = -2/3
y - intercept when x = 0
y = 2
x - intercept when y = 0

Joyce has $13 in savings and saves an additional $6 each week. At the same time, Enrique has $80 in savings and spends $5 each week to go swimming at the community pool. Is there a week when Joyce and Enrique will have the same amount of money? Explain why or why not.
Answer: Yes, after 7 weeks, they will have the same amount of money
Step-by-step explanation: So let’s say Joyce will be equation 1, so it would be - T = 13 + 6x, where T represents the total money, and x represents the number of weeks. And let’s say Enrique will be equation 2, which will be - T = 80 - 5x, where once again, T represents the total money, and x represents the number of weeks.
So, let’s start going off numbers, we will start at 5 weeks, when we put that in, Joyce will have $43 and Enrique will have $65, so we know it will be more than 5 weeks, so let’s try 8 weeks, Joyce will have $61 and Enrique will have $40, so it’s below 8, so how about we try 7, at 7 weeks, Joyce will have $55, and Enrique will have $55 too. So this means, after 7 weeks, Joyce and Enrique will have the same amount of money
If a "2" is rolled on a fair 6-
sided die, what event is most
likely to occur next?
A. a roll lower than 2
B. a roll higher than 2
C. another 2
D. all of these events are equally
likely
The event with the largest probability is rolling a number higher than 2, so the correct option is B.
Which event is most likely to occur next?First, the fact that a 2 was rolled before does not affect the next rolls of the dice, so that information is extra.
Now we just need to see which option has the largest probability.
A) There are only one number lower than 2, then the probability of this event is p = 1/6
B) There are 3 numbers higher than 2, then the probability is p = 3/6 = 1/2
C) The probability of get another 2 is 1/6
We can see that the event with the largest probability is B, so that one is the most likely to occur.

Ian wants to ride his bicycle 36.5 miles this week he has already written 8 miles if he rides for five more days which equation could be used to determine M the average number of miles he would have to ride to meet his goal?
Answer:
M = (36.5-8)/5
[M = 5.7 miles/day]
Step-by-step explanation:
The goal is 36.5 miles. The remaining miles needed to achieve this goal is reduced by the miles already ridden, 8 miles.
(36.5 - 8) = 28.5 miles remaining.
We are asked to find a value for M, which is the average number of miles Ian would have to ride to reach his goal. By average, we can assume it is the average miles/days remaining. The days remaining are 5, so we have:
(28.5 miles remaining)/5 days = 5.7 miles/day
An equation for M using these steps would be:
M = (36.5-8)/5

The angles are congruent and the ratios of sides are equal, then the polygons are similar.
What is the similarity of polygons?
The similarity of polygons refers to the relationship between two or more polygons in which the corresponding angles are congruent (equal in measure) and the corresponding side lengths are in proportion.
We have,
Polygon 1:
Opposite Sides 24 = 24, 12=12,
Angles = 90°
Polygon 1:
Opposite Sides 16 = 16, 8=8,
Angles = 90°
This means that if two polygons are similar, their corresponding angles will have the same measure, and their corresponding side lengths will be in the same ratio. In other words, the ratio of any pair of corresponding sides of similar polygons will be the same.
For example, two triangles are similar if the ratio of their corresponding sides is the same, and their corresponding angles are equal. Similarly, two quadrilaterals are similar if the ratio of their corresponding sides is the same and their corresponding angles are equal.
It's important to note that similarity is a stronger relationship than congruence, because in congruence all the sides and angles must have the same measure, while in similarity only the angles and ratios of sides are the same.
Additionally, the similarity of a polygon can be determined by measuring the angles of the polygon, and comparing the ratios of the corresponding sides.
If the angles are congruent and the ratios are equal, then the polygons are similar.
Hence, the angles are congruent and the ratios of sides are equal, then the polygons are similar.

The table gives a partial set of values of a polynomial h(x), which has a leading coefficient of 1.
x –2 0 1 2 3
h(x) 0 –12 0 8 0
If every x-intercept of h(x) is shown in the table and has a multiplicity of one, what is the equation of the polynomial function?
h(x) = x3 – 2x2 – 5x + 6
h(x) = x3 – 6x2 + 11x – 6
h(x) = x3 + 2x2 – 5x – 6
h(x) = x4 + 14x3 + 19x2 – 66x – 72
The equation of the polynomial function is (a) h(x) = x^3 - 2x^2 - 5x - 6
How to determine the equation of the polynomial function?From the question, we have the following parameters that can be used in our computation:
x –2 0 1 2 3
h(x) 0 –12 0 8 0
The x-intercepts are where y = 0
So, we have
x = -2, x = 1 and x = 3
The multiplicity is 1
So, we have
h(x) = (x + 2)(x - 1)(x - 3)
Expand
= (x + 2)(x^2 - 4x + 3)
This gives
= x(x^2 - 4x + 3) + 2(x^2 - 4x + 3)
So, we have
= x^3 - 4x^2 + 3x + 2x^2 - 8x + 6
Evaluate the like terms
= x^3 - 2x^2 - 5x - 6
So the equation is h(x) = x^3 - 2x^2 - 5x - 6

f(x) =(x - 5)/3 find the inverse function of this
The inverse function of f(x) = (x - 5)/3 is f^-1(x) = 3x + 5.
What is inverse function? How to calculate it? In mathematics, an inverse function is a function that undoes the work of another function. Specifically, if the function f applied to an input x gives a result of y, then the inverse function of f, denoted as f−1, applied to y gives the result x. In other words, the inverse of the function "f" applied to y will give us the input that we originally used to obtain y.To calculate an inverse function, one must first identify the original function. Then, one must switch the x and y variables, and solve for y. This is done by isolating the y in the equation and replacing it with the inverse function. For example, if the original equation is y = x + 4, then the inverse equation is x = y - 4.Once this is done, one can then determine the inverse function by taking the reciprocal of the function. This can be done by changing the sign of the exponent for any exponentiated terms and changing the sign of the coefficient for any multiplied terms. For example, if the function is y = x2 + 2x + 4, then the inverse function is y = (1/x2 + 2/x + 4)−1.In summary, to calculate an inverse function, one must first identify the original function, switch x and y, and solve for y, and then take the reciprocal of the expression.Solution:
To find the inverse of a function, we need to switch the x and y variables, and then solve for y.
Starting with f(x) = (x - 5)/3, we can switch the x and y variables to get y = (x - 5)/3.
We can then solve for x by multiplying both sides by 3, giving us 3y = x - 5.
We can then add 5 to both sides to get 3y + 5 = x, which is the inverse of our original function.
Therefore, the inverse of f(x) = (x - 5)/3 is f^-1(x) = 3x + 5.
