In the interval where the function is decreasingcreasing, the input or x values increase as the output or y values decrease. Looking at the graph, moving from the left to the right, the values of x are increasing whie the values of y are decreasing. This trend continued till we got to x = 0.5. Thus, in the interval from negative infinity to x = - 0.5, the function was decreasing.

The correct option is C

Suppose C = 20y + 15 and y = 50x + 5. Which of the following is equivalent to C = 20y + 15, but written only in terms of x?
Olegator [25]

Answer:

C = 1000x + 115 (Answer B)

Step-by-step explanation:

We know that..

C = 20y + 15

y = 50x + 5

So put the Y value in the equation of C

C = 20 (50x + 5) + 15

C = 1000x + 100 +15

C = 1000x + 115
