Answer: y=3x-7

Step-by-step explanation:

First you have to get the equation in slope intercept form by moving x over then dividing by -1 because y cannot be negative

Then since you're trying to find the line that is parallel you use the same slope which is 3x

You then plug in the points which is 2=3(3) + b for you are trying to find teh y intercept

You then solve as normal and get y=3x-7

I am pretty sure this is correct

The average rate of change of a function f(x) = x2 between x = 3 and x = 9 is

masya89 [10]

Answer:

12.

Step-by-step explanation:

Average rate of change = (value of the function when x = 9 - value when x=3)

(9 - 3)

= f(9) - f(3) / (9-3)

= (9^2 - 3^2) / (9-3)

= 72 / 6

= 12.

Find the perimeter of triangle PQR. Round your answer to the nearest tenth.

BabaBlast [244]

We are given the coordinate of the 3 vertices. From these coordinates we can find the length of the sides using the distance formula and the sum of all the sides will be equal to the perimeter of the triangle.

Side PQ = $\sqrt{ (6-(-2))^{2}+ (1-1)^{2} }=8$

Side QR = $\sqrt{ (4-6)^{2}+ (-3-1)^{2} }=4.5$

Side RP = $\sqrt{ (2-(-4))^{2}+ (-3-1)^{2} }=7.2$

So, the perimeter of the triangle will be 8 + 4.5 + 7.2 = 19.7

You probably misplaced the digits in option A. The correct answer is 19.7 units.
