|4r + 8| ≥ 32

4r + 8 ≥ 32         or         4r + 8 ≤ -32      <em> inside of absolute value could be + or -</em>

4r       ≥ 24         or          4r       ≤ -40       <em>subtracted 8 from both sides</em>  

r       ≥  6           or            r       ≤ -10         <em>divided both sides by 4</em>

Graph: ←---------------- -10        6 ------------------→

Interval Notation: (-∞, -10] U [6, ∞)

Okay here are the steps to solving this inequality:

First- <u><em>Break down the problem into these 2 equations</em></u>

               4r + 8 ≥ 32    →    - (4r + 8) ≥ 32


Second- <u>Solve the 1st equation: </u><u><em>4r + 8 ≥ 32</em></u>

                    r ≥ 6


Third- <u>Solve the 2nd equation: - (4r + 8) ≥ 32</u>

                    r ≤ -10


Lastly- <u>Collect all solutions </u>

<h2>           r ≥ 6   and   r ≤ -10</h2>

-3x+3y=12<br> Y=x+4<br> Whats the soultion
lisov135 [29]

The system of equations has infinitely many solutions

<em><u>Solution:</u></em>

<em><u>Given system of equations are:</u></em>

-3x + 3y = 12 ------- eqn 1

y = x + 4 --------- eqn 2

We have to find the solution to the system of equations

We can use substitution method

Substitute eqn 2 in eqn 1

-3x + 3(x + 4) = 12

-3x + 3x + 12 = 12

-3x + 12 = -3x + 12

If we have terms with same terms on both sides of equal sign, then we have infinitely many solutions

Thus the system of equations has infinitely many solutions

Please help me with this (i attached photos to cause less confusion) <br><br> Thanks :) 25 Points!!!
navik [9.2K]

Answer:

See below

Step-by-step explanation:

The first two questions are slope = 0

   a horizontal line has zero slope  

            slope = rise/run  = 0 / run = 0

Greatest y value is + 4   from x = 3 to 4

the least y value is -3 fro x = -4 to -3

Find the Surface Area of the prism pleese
Alina [70]

Answer:

I'm unsure of the answer but here's how to solve it yourself :)

Step-by-step explanation:

area of a prism is obtained by taking the sum of (twice the base area) and (the lateral surface area of the prism). The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where "S" is the surface area of the prism.

Please help and explain why you got it right please
gtnhenbr [62]

Answer:

y+7 = -3 ( x-4)

Step-by-step explanation:

First find two points on the graph to find the slope

( 1,2) and ( 3,-4)

The slope is given by

m = ( y2-y1)/(x2-x1)

m = ( -4-2)/(3-1)

    = -6/2

    =-3

We can use the point slope form

y - y1 = m(x-x1)  where m is the slope and x1,y1 is a point on the line

We have two choices with a slope of -3

We can either use and x coordinate of -2 or 4

for  -2, the y coordinate is not shown

for 4 , the y coordinate is -7

Using ( 4, -7) and m = -3

y--7 = -3( x- 4)

y+7 = -3 ( x-4)
