Answer:
C. 6
Step-by-step explanation:
Looking at the value of AC, you can assume that it is the same value as CD because it is divided in the middle with a 90-degree angle in which it is 12. Assuming that the line BF is also divided in half, you should divide 12 by 2 in which you get the final answer as 6.
The range is: B. {12, 4, -6}
Step-by-step explanation:
Given
12x + 6y = 24
Here x is the input and y is the output
So,
Replacing y with f(x)
Domain = {-4, 0, 5},
We will put the elements of domain, one by one, to find range
Hence,
The range is: B. {12, 4, -6}

Reflect over x=-3 if that's what you mean
The correct answer is option A. Which is the solution of the given equation will be (15,15).
<h3>What is an equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given equations are solved as:-
a - 1.2b = -3 or a = -3 + 1.2b
0.2a + 0.6b = 12
Put the value of a from equation 1 to the equation second.
0.2 ( -3 + 1.2 b) + 0.6b = 12
-0.6 + 0.24b + 0.6b = 12
0.84b = 12 + 0.6
0.84 b = 12.06
b = 15
Put the value of b in the first equation to find the value of a.
a = 1.2b - 3
a = (1.2 x 15) - 3
a = 15
Therefore the correct answer is option A. Which is the solution of the given equation will be (15,15).
