The measure of an angle is 4y. Find the measure of its complement.A) 90 - 4y
B) 90 + 4y
C) 180 - 4y
D) 180 + 4y

Answers

Complementary angles are angles whose measure add up to 90°.

So, if one angle is 4y, the complementary angle is 90°- 4y. Choice A.

Complementary angles does not necessarily need to share a line or vertex. As long as both angles have a sum of 90°, then, they are complementary angles.

Angles who has a sum of 180° are called supplementary angles.

8x-2=-9+7x can you do it step by step

Answers

In going to move constants to one side and variables to another by adding and subtracting.

8x -2 + 2 - 7x = -9 + 2 + 7x -7x

8x -7x = -9 + 2
Now solve

X = -7

well u move all the variables to the left side, so 8x is already in the left but 7x isnt so you move 7x to the left side of the equal sign which makes 7x to -7x.

8x-2-7x=-9

you move the -2 to the right side of the equal sign which becomes +2.

8x-7x=-9+2

you do the math which 8x-7x=1x and -9+2=-7

so.... 1x=-7

and x=-7. Make sure to always combine like terms.

To make sure it is correct replace the x with the -7 and

8(-7)-2=-9+7(-7)

-56-2=-9-49

-58=-58

so x= -7

solve each inequality using addition and subtraction and graph it's solution set on a number line x + 8 > 14

Answers

x+8>14

Subtract 8 from both sides-
x>6

Do you need help with the graphing part too?

Hi there!

Step-by-step explanation:

First, you subtract by 8 from both sides of an equation.

x+8-8>14-8

Then, you subtract by the numbers from left to right.

14-8=6

The answer must have a positive sign.

Answer: →→ x>6

Hope this helps!

Have a nice day! :)
