Answer:

false

Step-by-step explanation:

This is a solution to the first equation because

5+-9=-4

-4=-4

however, if you plug it into the next equation, it becomes false.

5--9=4

14=4

this does not make sense.

PLEASE ANSWER + BRAINLIEST!!!!

So, let's begin...
First off, you must note that the question is asking for the d value when you substitute the value of c(x).
You are given the following information:
1. The c(x) value is already given to be 0.75x.
2. The equation to find d of (any value) is 0.8y-5.

So, substitute the value of 0.75x as a y value into 0.8y - 5. This is because you are substituting the value of c(x) for d. This is equal to 0.8 times 0.75x - 5. This is equal to 0.6x - 5, which is the function. Thus, your final answer is d(c(x)) = 0.6x - 5.
If you have any questions please comment. Otherwise, hope this helps! :)
