Notice the table of values
when x = 2, y = -5
then "x" goes 2 units over to 4, and "y" moves over to 5, now from -5 to 5 is 10 units, so when "x" moved just 2 units, "y" went 10.
then "x" goes further down to 7, moving 3 units over,
and "y" goes further from 5 to 20? what the? it went 15 units.
so.... hmmm notice, is we do some quick splitting and instead check how much "y" is moving for every unit on "x".
notice, on 2 units of "x", "y" moved 10 units
and on 3 units of "x", "y" moved 15 units, like from 5 to 20.
so, "y" is really moving 5 units on every unit moved by "x", so the "rate of change" or slope is indeed constant, is 3 to 1 all the way.
The y-intercept of the graph shows that at m = 0, c = 15. We can see a constant slope that causes the graph to pass through m = 20, c = 20, as well as m = 40, c = 25. This shows a constant increase of $5/20 minutes, or a slope of 5/20 = 1/4. Based on slope-intercept form y = mx+b, the equation would be c = (1/4)m+15, from 0 <= m <= 44,640. This is the second of the given choices.

Step-by-step explanation:
2 × 
= 2 × 10 × 10 × 10 × 10
= 2 × 100 × 100
= 200 × 100
= 20000
And
= 2 × 2 × 2 × 2
= 4 × 4
= 16
Answer:
Step-by-step explanation:
4(5-2)+(-7)(0.5)
20-8+(-3.5)
12-3.5
8.5
The answer is 60
because first you subtract 10 on both sides
then multiply 4 on both sides getting v=60
