Graph the direct variation y=−1.5x. find the value of x when y= −3; 4.5; 6 when y = −3, x = when y = 4.5, x = when y = 6, x =

When y = −3, x =2

When y = 4.5, x =-3

When y = 6, x = -4

Step-by-step explanation:

Given equation:

To find x divide both sides by -1.5 , we get

When y = −3,

When y = 4.5,

When y = 6,

So we have points to plot the line to show direct variation on graph as below.

(2,-3), (-3,4.5) and (-4,6)

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

answer: 72: 111
