Answer:
True
Step-by-step explanation:
To answer this question, I will use the following illustrations.
Assume a point (x,y) is reflected across the x-axis.
Using reflection rule, the new point will be: (x,-y)
On a coordinate plane, the x-axis is represented as: (x,0)
So, we will calculate the distance between (x,y) and (x,0) and also calculate the distance between (x,-y) and (x,0) using the following distance formula.
[tex]D= \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Distance between (x,y) and (x,0)
[tex]D= \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
[tex]D= \sqrt{(x - x)^2 + (0 - y)^2}[/tex]
[tex]D= \sqrt{(0)^2 + (- y)^2}[/tex]
[tex]D= \sqrt{0 + y^2}[/tex]
[tex]D= \sqrt{y^2}[/tex]
[tex]D = y[/tex]
Distance between (x,-y) and (x,0)
[tex]D= \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
[tex]D= \sqrt{(x - x)^2 + (0 - (-y))^2}[/tex]
[tex]D= \sqrt{(0)^2 + (0+y)^2}[/tex]
[tex]D= \sqrt{0 + y^2}[/tex]
[tex]D= \sqrt{y^2}[/tex]
[tex]D = y[/tex]
See that the calculated distance are equal.
Hence, the given statement is true

Answer:
so.. this means that they're equal...
so.. 8 + x = 35
u need to solve for x...
so u do, 35 - 8 = 27
so it would be..
and 27 divide 3 = 9
so x = 9
so the equation would be...
(3 x 9 + 8) = 35
SO, the answer is 9

what is the factored form of 3/4(24x + 28) - (4x - 1)?
Answer:
2(7x + 11)
Step-by-step explanation:
3/4 ( 24x + 28) - (4x - 1) = 18x + 21 - 4x + 1 = 14x + 22 = 2(7x + 11)
Answer:
2(7x + 11)
Step-by-step explanation:
3/4 (24x + 28) - (4x - 1)
= 18x + 21 - 4x + 1
= 14x + 22
= 2(7x + 11)

Cole learned that newly-minted
coins are put into bags. The
mint puts 2,000 half-dollar
coins into 1 bag. What is the
value of 11 bags?
Answer:
11000 dollars.
Step-by-step explanation:
Interesting question.
1 bag has 2000 half dollars in it.
2000 half dollar coins have a value of 2000 * 1/2 = 1000 dollars.
11 bags = 1000 * 11 = 11000 dolars.

The set of values (63, 64, 65, 66} represents solutions of which inequality?
Answer: 63 < N ≤ 66
Step-by-step explanation:
We have the set:
(66, 64, 65, 66]
First.
When we have an end with the signs "(" or ")" means that the element near the sign does not belong to the set, this would be an "open" end. Usually used for the symbols > and <
While the sign "[" or "]" (in some cases the symbols { and } are used instead)
means that the value next to it are included in the set. Usually used for the symbols ≤ and ≥.
Then in the set: (63, 64, 65, 66} the value 63 does not actually belong, and value 66 does belong.
Then this set is written as:
63 < N ≤ 66
Such that N is an integer number.

Write log7(2 ⋅ 6) + log73 as a single log. Log Subscript 7 Baseline 11 Log Subscript 7 Baseline 15 Log Subscript 7 Baseline 36
Answer:
C. log7 36....................................
The given logarithmic expressions together can be written as log₇ 36
What is a logarithmic function ?The logarithmic function is an expression which we can write as, y = logₐx, where a>0 & x>0, It is the inverse of exponential function.
Formulae for logarithmic function are,
LogAB = LogA + LogB
Logₐaᵇ = b
Given that,
= log₇(2 x 6) + log₇3
= log₇ 36
We have the result
log A + log B = log AB
Here the question is log₇(2 x 6) + log₇3.
Using the property of logarithm we will get,
= log₇(2 x 6) + log₇3
= log₇(2 x 6 x 3)
= log₇ 36
So, log₇(2 x 6) + log₇3 = log₇ 36

will a one variable equation always have only one solution
Answer:
Every linear equation that is a conditional equation has one solution. However, not every linear equation in one variable has a single solution. There are two other cases: no solution and the solution set of all real numbers. ... Therefore, the equation is always true.
Step-by-step explanation:
We want to see if a one-variable equation always has only one solution.
This is false, as one-variable equations can have no solutions or more than one solution.
So we start with the statement:
"A one-variable equation always has only one solution".
We need to find a counterexample to prove that this is false, and there are really easy counterexamples, like:
x^2 - 4 = 0
This is a one-variable equation, and solving it we have:
x^2 = 4
x = ± √4 = ±2
So here we have two solutions, 2 and -2, thus the statement is false.
