Answer:
$900
Step-by-step explanation:
60/4 = 15
60 x 15 = 900
X-5=2-3x+9
x-5=-3x+11
4x-5=11
4x=16
x=4
The proportionality for the table values would be an increasing value of 1.5y for every X.
The equation of perpendicular bisector of QR is:

Step-by-step explanation:
Given points are:

First of all, we have to find the slope of the given line
So,

Here
(x1,y1) = (-2,0)
(x2,y2) = (6,12)
Let m1 be the slope of QR:
Then

Let m2 be the slope of perpendicular bisector
We know that the product of slopes of two perpendicular lines is -1

The bisector will pass through the mid-point of QR

Slope-intercept form of equation is:

Putting the value of slope

Putting (2,6) in the equation

So,

Hence,
The equation of perpendicular bisector of QR is:
