Answer:

x =4.5 hours

Step-by-step explanation:

We can use ratios to solve

150 miles        270 miles

--------------- = --------------

2.5 hours      x miles

150 *x = 270*2.5

Divide each side by 150

150x/150 = 270*2.5/150

This is often achieved when there's uniformity in slope x and y.

4. Weak Correlation

This is achieved when there's no uniforms in slope x and y

Y=-3x+6 y=9 What is the solutions to the system of equations?
Damm [24]

Answer:

(- 1, 9 )

Step-by-step explanation:

One of the equations gives y = 9, the y- value

To find the value of x, substitute y = - 3x + 6 , that is

- 3x + 6 = 9 ( subtract 6 from both sides )

- 3x = 3 ( divide both sides by - 3 )

x = - 1

Solution is (- 1, 9 )
