What is the solution to the system that is created by the equation y=-x+6 and the graph shown below?
mina [271]
The graph graphed is y=1/2x

so
y=1/2x and y=-x+6
y=y so
1/2x=-x+6
times 2 both sides
x=-2x+12
add 2x both sides
3x=12
x=4

sub back
y=1/2x
y=1/2(4)
y=2

(4,2) is the solution

A property of rectangles is that opposite sides are congruent. In this case, since QT and RS are opposite sides, they are equal to each other. With this knowledge, you can form the equation 50=4x+8 to solve for x.

Firstly, subtract both sides by 8: 42=4x

Next, divide both sides by 4 and your answer will be 10.5=x, or the third option.

750 = 4a

750/4 = a

<u>187.5ms^2</u>

2)

For every one second it travels 12.3 meters therefore you can just do 12.3x25 = 307.5m
