During 30 minutes on the treadmill, latoya burned 20 calories per minute. what is the rate of change of the function that represents this situation? 10 calories per minute 20 calories per minute 30 calories per minute 50 calories per minute

The rate of change is 20 calories per minute.

Step-by-step explanation:

Since we have given that

Number of minutes he is on the treadmill = 30 minutes

Number of calories burned per minute = 20 calories per minute

We need to find the rate of change of the function.

Rate of change means here, change in calories per minute , in short, number of calories is burnt per minute., which is given 20 calories per minute

Hence, the rate of change is 20 calories per minute.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
