Answer:
88 cars
Step-by-step explanation:
8x-3x=5x
40 cars = 5x
divide both sides by 5
x=8 cars
8x+3x=11x
11x=88 cars altogether
Answer:
x=-2
Step-by-step explanation:
divide both sides by 3
you get x=-2
go to -2 on the x axis and draw a line straight down, x=-2 will intercept the x axis at the point -2
same thing for y=-5 (example)
go down five on the y axis and draw a horizontal line to the y axis intercepting at point (0,-5)
<u>Change</u> of PE over a height of 10m = M G H = (10) (9.8) (10) = 980 joules.
When the box hits the bottom, it has 980 joules <u>less</u> PE than it had
before it started dropping.
(As well as 980 joules <u>more</u> kinetic energy.)
