Answer:

a) x = 5

b) x = 12

Step-by-step explanation:

x + 3 = 8

Subtract 3 on both sides.

x = 8 - 3

x = 5

x - 5 = 7

Add 5 on both sides.

x = 7 + 5

x = 12

Answer:

m = -3

Step-by-step explanation:

First, find two clear points:

(1, -2) (0, 1)

Then, use the slope formula:

m = <u>y2 - y1</u>

      x2 - x1

m = <u>1 - (-2)</u>

       0 - 1

   = <u>3</u>  = -3

     -1

m = -3

This means that the rise-over-run is -3 over 1, or 3 over -1.

Which means three down and 1 to the right, or 3 up and 1 to the left.

Slope is the steepness of the line.

A car and a limo each drive along a straight road between two points. Using the points on a map that the city created, the car w
garik1379 [7]
The path of the car and the limo are straight lines. To determine the equation of the lines of the paths, the slopes must be determined. Let m1 = slope of car m2 = slope of limo so, m1 = (7 + 7)/(5 + 2) = 2 m2 = (-5 -9)/(3+4) = -2 therefore the equations are car: 2x – y = 2(5) –(7) 2x – y = 3 Limo: 2x + y = 2(3) – 5 2x + y = 1 Solving the intersection of the equations (using a calculator) x = 1 y = -1

Plz help me!!!<br><br> find the value of {3-2(3-4)^3}^3
maxonik [38]

Answer:

-226,981

Step-by-step explanation:

This is how you do it.

First, you do 3-2 which is 1.

Then, you do 3-4 to the 3rd power which is -61.

After, you do 1*-61 because there are parenthesis, which equals -61.

Then, you do -61, which is the total of everything in parenthesis, and do it times the power of 3 to get -226,981.

Hope it helps!!^_^
