Answer: 
Step-by-step explanation:
Creating identical expressions involves changing quantities in a way that preserves the end values specified in the equation.
For instance, if Lei sold 4 carnations:

In the second equation listed, the expression (8 + 0.25c) was multiplied by 4, then by 0.25, for a total multiplicand of 1.
You can make a third equation through the same method. I'll multiply (8 + 0.25c) by 2, and then multiply that expression by 0.5 to keep the multiplicand unchanged:

If Lei sold 4 carnations:
0.5 * (16 + 2) = 9
This equation represents the same quantities as the other equations.

Step-by-step explanation:
b= 1/4 + 3 1/2
Answer:
C
Step-by-step explanation:
The parent graph of this function is the absolute value, or |x|. However, it is shifted 8 units to the right and 2 units up. Therefore, the equation of this function is y=|x-8|+2, or answer choice C. Hope this helps!
