What is 35 = -2x - 15 ?

gtnhenbr [62]

Answer:

x=-25

Step-by-step explanation:

35=-2x-15

add 15 to both sides, cancels the 15 from the right

50=-2x

What is the measure of an angle that is it’s own complement ?

ValentinkaMS [17]

A complement is angle that can be added to another to equal 90 degrees.

So two times the same number would equal 90.

90 / 2 = 45

The angle that is its own complement is 45 degrees.

Subtract and simplify.

Anestetic [448]

$(y^2-7y-5)-(-3y^2+3y-4)$
$=y^2-7y-5+3y^2-3y+4$
$=3y^2+y^2-7y-3y-5+4$
$=4y^2-10y-1$

In short, the answer would be $4y^2-10y-1$ (Option D).

Hope this helps !
