Answer:

see the explanation and the attached figure

Step-by-step explanation:

we have

-2(x+1)=8 ----> given

Divide by -2 both sides

-2\frac{(x+1)}{-2} =\frac{8}{-2} ----> by Division Property of Equality

Simplifying

x+1=-4

Subtract 1 both sides

x+1-1=-4-1 ----> by Subtraction Property of Equality

Simplifying

x=-5

5x-3-2x/7=24 solve for x
bearhunter [10]

Answer:

X=5.7

Step-by-step explanation:

5x-3-2x/7=24

We simplify the equation to the form, which is simple to understand  

5x-3-2x/7=24

Simplifying:

5x-3-0.285714285714x=24

We move all terms containing x to the left and all other terms to the right.  

+5x-0.285714285714x=+24+3

We simplify left and right side of the equation.  

+4.71428571429x=+27

We divide both sides of the equation by 4.71428571429 to get x.  

x=5.72727272727

a rectangle is transformed according to the rule r0, 90º. the image of the rectangle has vertices located at r'(–4, 4), s'(–4, 1
AleksandrR [38]
Graph images undergo transformations, one of the types of transformations are rotations.
rotation is done when each point of the image rotates 90° around a point in the counterclockwise manner. 
when rotation is done, (x,y) -> (-y,x)
therefore when taking points from image to original then the reverse is done ;
(-y,x) --> (x,y)
the coordinates of  image point q' is (-3,4)
before rotation then the coordinates are (4,3)
answer is (4,3)

-104=-8(k+8) <br><br> K = ?<br> Solution please if can?
maksim [4K]

Let's solve this question by step by step.

Layout equation.

−104=−8(k+8)

Step 1: Simplify both sides of the equation.

−104=−8(k+8)

−104=(−8)(k)+(−8)(8)(Distribute)

−104=−8k+−64

−104=−8k−64

Step 2: Flip the equation.

−8k−64=−104

Step 3: Add 64 to both sides.

−8k−64+64=−104+64

−8k=−40

Step 4: Divide both sides by -8.

-8k/-8=-40/-8

The answer for this problem is k=5.
