x+2 = -x+6
2x+2 = 6
2x = 4
x = 2

Both equal y to set equal to each other
x+2=y=-x+6
x+2=-x+6
add x both sides
x+x+2=x-x+6
2x+2=0+6
2x+2=6
minus 2 both sides
2x+2-2=6-2
2x+0=4
2x=4
divide both sides by 2
x=2

the x coordinate is 2

Determine if the given ordered pair is a solution to the equation. Show work full.

sleet_krkn [62]

Answer:

The ordered pair is not a solution of the equation

Step-by-step explanation:

we know that

If a ordered pair is a solution of a linear equation, then the ordered pair must satisfy the linear equation

we have

$y=-3x-13$

Substitute the value of x and the value of y of the given ordered pair in the linear equation and analyze the results

For x=-1, y=15

$15=-3(-1)-13$

$15=3-13$

$15=-10$ ----> is not true

the ordered pair not satisfy the equation

therefore

The ordered pair is not a solution of the equation

Answer:

c. In 2 seconds, the commuter train travels 120 feet.

Step-by-step explanation:

Given

The attached graph

Required

What does x-coordinate of 2 represents

Represent this coordinate with (x,y)

From the graph:

$x = 2$ when $y = 120$

Note that:

x = time and y = distance

So:

$(x,y) = (2,120)$

Which means:

At 2 seconds, the train has travelled a distance of 120ft

From the list of options, (c) is correct
