Answer:

the ordered pair will be (1, 2)

Step-by-step explanation:

first of all substitute the x and y values into the equation in other to make the equation true.

Therefore y=4x-7

1 = 4(2) -7

1 = 8 -7

1 = 1

Making the first equation true. then move to the second equation which is y = - x + 3

1 = -(2) + 3

1 = 1

I hope this helps though

Answer:

3.7hours

Step-by-step explanation:

Step one:

A car travels 360 miles in 8 hours

the speed is calculated as

speed= distance/time

speed= 360/8

speed= 45mph

Step two:

How much time will it take traveling 168 miles?

having found the speed, which is the rate at which the car is tavelling

time= distance/speed

time= 168/45

time= 3.7hours

Answer:

Midpoint of (-6, 3) and (8, -7) is: (1, -2)

Step-by-step explanation:

Given the points

Computing the midpoint of (-6, 3) and (8, -7) using the formula

⇒  [tex]\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-6,\:3\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)[/tex]

⇒  [tex]\left(\frac{8-6}{2},\:\frac{-7+3}{2}\right)[/tex]

⇒  [tex]\left(1,\:-2\right)[/tex]

Therefore, Midpoint of (-6, 3) and (8, -7) is: (1, -2)

Answer:

32+10=7x

Step-by-step explanation:

Let's solve this first. 32$ is the final price, and then add 10$ because of the gift card, leaving you with 42$. Divide the 42 by 7, because each CD is 7 dollars. The result is 6. So put that into an equation.

32+10=42=7x

x=6!
