Answer:
the answer is -10
Step-by-step explanation:
x=x
y=5
then
3x+5y=-5
3x+5*5=-5
3x=-5-25
3x=-30
x=-30/3
•°•x=-10

Answer:
- 6
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
here [ a, b ] = [ 1, 5 ]
f(b) = f(5) = 17 - 5² = - 8
f(a) = f(1) = 17 - 1² = 16
average rate of change = = = - 6
