Part 6: what do you mean by 'if h can 36'?
Part 7: h=3, correct
Step-by-step explanation:
3+h=-3+9
h=-3+9-3
h=3
Answer:
The average rate of change = 4.
Step-by-step explanation:
Here we have formula.
Average rate of change = f(b) - f(a)
-----------
b - a
Given: f(X) = x^2 + 5x - 12 interval [-2, 1]
Here a = -2 and b = 1
f(a) = f(-2) = (-2)^2 + 5(-2) -12
= 4 -10 -12
f(-2) = -18
f(b) = f(1) = (1)^2 + 5(1) - 12
= 1 + 5 -12
f(1) = 6 -12
f(1) = -6
Now apply these values in the above formula, we get
Average rate of change = [-6 - (-18)] / [1 -(-2)]
= [ -6 +18]/1 +2
= 12/3
= 4.
Therefore, the average rate of change = 4.
Hope this will helpful.
Thank you.
Answer:
The y-variable will be eliminated when adding the system of equations.
There is only one solution to the system of equations.
Step-by-step explanation:
-x + 6y = 16 (1)
8x - 6y = -2 (2)
Add the equations to eliminate y
-x + 8x = 16 +(-2)
7x = 16 -2
7x = 14
x = 14/7
x = 2
Substitute x = 2 into (1)
-x + 6y = 16 (1)
-2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
(x, y) = (2, 3)
Answer:
a
Step-by-step explanation:
a linear function have a shape of y=ax+b
y=8x-3 is linear where a=8 and b=-3
