– 72 = 3(- 4x – 8) Need help

Mathematics
1 answer:
Finger [1]3 years ago
8 0

Answer:

x = 4

Step-by-step explanation:

Step 1: Write equation

-72 = 3(-4x - 8)

Step 2: Solve for <em>x</em>

<u>Distribute 3:</u> -72 = -12x - 24

<u>Add 24 to both sides:</u> -48 = -12x

<u>Divide both sides by -12:</u> x = 4

Step 3: Check

<em>Plug in x to verify if it's a solution.</em>

-72 = 3(-4(4) - 8)

-72 = 3(-16 - 8)

-72 = 3(-24)

-72 = -72

Which statements must be true about the image of ΔMNP after a reflection across Line E G? Select three options. The image will b
masya89 [10]

Answer:

The image will be congruent to ΔMNP.

Line EG will be perpendicular to the line segments connecting the corresponding vertices.

The line segments connecting corresponding vertices will all be parallel to each other.

Step-by-step explanation:

The reflected image will be the mirror image of ΔMNP, so it will be congruent.  The lines connecting each vertex to the corresponding vertex will be parallel, and all three lines are perpendicular to EG.

Solve the equation square root X-6+2 = 6 for the variable. Show each step of your solution process
zhannawk [14.2K]
The first step would be to isolate the square root on the left side.  √x-6+2 = 6 √x-6 = -2+6  √x-6 = 4We would have to take away the radical on the left and square the equation.  (√x-6)2 = (4)2 x-6 = 16Finally, x -22 = 0 x = 22
