Answer:

Step-by-step explanation:

Hello There!

For this one all we have to do is plug in the values

Remember l l means absolute value

l -5 - 4 l - l 1 + (-3)l

-5-4=-9

l-9l the absolute value of -9 is 9

1-(-3)=-2

l-2l the absolute value of -2 is 2

we´re left with

9-2

9-2=7

so the answer to the problem is 7

3x + 3<br> X + 8<br> What is the perimeter of each polygon?

Ganezh [65]

Answer:

D. 60

Step-by-step explanation:

4(3x + 3) = 5(x + 8) 12(4) + 12 5(4) + 40

12x + 12 = 5x + 40 48 + 12 20 + 40

-5x -5x 60 60

7x + 12 = 40

-12 -12

7x = 28

x = 4

Which of the following graphs shows the solution for the inequality<br> y-4> 2(x+2)?

timofeeve [1]

Answer:

Answer:

Graph C shows the solution for the inequality

Step-by-step explanation:

y - 4 > 2(x + 2)

y > 2x + 4 + 4

y > 2x + 8

Let y = 2x + 8, Then

X-intercept (0, 8)

Y-intercept (-4, 0)

Since the inequality sign is > we use broken line.

Put, (0, 0)

y > 2x + 8

0 > 0+ 8

0 > 8 Which is false

so, the answer will be above the broken line

Hence , Graph C shows inequality

Solve for x -9<4x+3<27 enter your answer as one inequality in the box

ludmilkaskok [199]

If a< c< b then a<c and c<b

Separate the equation into 2 separate ones and solve them:

X-9 < 4x +3

Subtract 3 from both sides:

X-12 < 4x

Subtract x from both sides:

-12< 3x

Divide both sides by 3:

X > -4

4x+3 < 27

Subtract 3 from both sides

4x < 24

Divide both sides by 4

X <6

Combine to get one inequality:

-4<x<6
