Answer:
78
Step-by-step explanation:
Step 1: Substitute -3 for x
6(2x^2 - 5)
6(2(-3)^2 - 5)
6(2(9) - 5)
6(18 - 5)
6(13)
78
Answer: 78
Answer:
?=78
Step-by-step explanation:
You plug in -3 for x. -3^2 is 9. Multiply 2*9 and subtract 5 from that. Get 13. Multiply 6 and 13 to get 78

A. 14x – 2y = 8
B. y = 6x – 5
C.

D.
The Graph is Letter D.

A.
Convert to slope-intercept form.
Subtract 14x to both sides:
Divide -2 to both sides:
So the rate of change here is 7.
B.
This is already in slope-intercept form, so the rate of change here is 6.
C.
Take any two points on the graph and plug them into the slope formula.
Let's take (-1, -2) and (0, 3).
x1 y1 x2 y2
Plug in the numbers:
Subtract:
Divide:
So the rate of change here is 5.
D.
Take any two points on the line and plug them into the slope formula.
Let's take (0, -2) and (1, 3)
x1 y1 x2 y2
Plug in the numbers:
Subtract:
Divide:
So the rate of change here is 5.
Therefore, A has the greatest rate of change.
