z = -11

Steps:
8z+12 = 5z-21
Subtract 12 from both sides
8z+12-12 = 5z-21-12
Simplify
8z = 5z-33
Subtract 5z from both sides
8z-5z = 5z-33-5z
Simplify
3z = -33
Divide both sides by 3
3z/3 = -33/3
Simplify
z = -11

Hope this helps you! (:

On square PQRS below, if Q is located at (7,0) and R is located at (5,-8) what is the length of SR
jenyasd209 [6]

the length of SR is 2\sqrt{17} .

<u>Step-by-step explanation:</u>

Here we have , On square PQRS below, if Q is located at (7,0) and R is located at (5,-8) . We need to find Length of side SR . Let's find out:

We know  that  , In a square there are  4 sides , and length of every side is same . So side length of SR = side length of QR . Now , Let's find side length of QR .

We know that distance between two points Q(x_1,y_1),R(x_2,y_2) given by :

⇒ QR = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Two points given are Q(7,0), R(5,-8) :

⇒ QR = \sqrt{5-7)^2+(-8-0)^2}

⇒ QR = \sqrt{(2)^2+(-8)^2}

⇒ QR = \sqrt{4+64}

⇒ QR = \sqrt{68}

⇒ QR = 2\sqrt{17}

But QR=SR , Therefore , the length of SR is 2\sqrt{17} .

what is the point slope of an equation of a line with the slope -13 that goes through the point (5,7)
irga5000 [103]

Remark

The general equation for the point slope form is

(y - h) = slope(x - k)

<em><u>Givens</u></em>

given point = (5,7) from which

h =  7

k =  5

slope = m = - 13

Equation

(y - 7) = -13(x - 5) Usually the equation is left like this.
