Option 1,2,3 are true hope it helps if not im sorry
Answer:

Step-by-step explanation:
Given:
Interval, [0, 4]
Required:
Average range of change over [0, 4]
SOLUTION:
Find f(0) and f(4) from the graph:
(when x = 0, y = 0)
(when x = 4, y = 3)
Average rate of change = 
Where,


Plug in the values into the formula for average rate of change.


Average rate of change 
Answer:
-3/5-13i/10
Step-by-step explanation:
Answer:
y = 2/3x + 6
Step-by-step explanation:
If two lines are parallel, that means their slopes are the same.
Rewrite 2x - 3y = 15 to y = 2/3x - 5
The slope is 2/3, so the answer should have a slope of 2/3 as well.
The equation is now y = 2/3x + b
To find b, substitute (-3,4)
y = 2/3x + b
4 = 2/3(-3) + b
4 = -2 + b
6 = b
So the equation is y = 2/3x + 6
<span>x : y is equal to 12 : 8. These can be reduced or cancelled down to 3 : 2 in the same proportions. Therefore, when y is 12, you have to multiply the smallest value y can be by 6, and must do the same to the smallest x value to retain the proportions. x = 18 when y = 12.</span>
