First we can recognize that angle OPQ shares a straight angle with angle QPR, meaning mQPR = 180 - 135 = 45 degrees. Given that angle PRQ is a right angle (90 degrees) and knowing that the interior angles of a triangle dum to 180, we can find that angle PQR (angle Q) is 180 - 90 - 45 = 45 degrees, and

tan(45) = 1

Which equation is an identity?
zloy xaker [14]
3w + 8 - w = 4w - 2(w - 4)
is an identity
3w-w + 8 = 4w - 2w + 8
2w + 8 = 2w + 8
2w - 2w = 8 - 8
0 = 0
zero equal to zero implies that any value of w satisfies the statement 3w + 8 - w = 4w - 2(w - 4) hence it is an identity.

What expression is the simplified form of “-12+5a-a-6a+8a+8+3a”? Please explain your reasoning.
kramer

Combine like terms:

-12 + 5a - a - 6a + 8a + 8 + 3a

-12 + 5a - a - 6a + 8a + 8 + 3a

5a - a = 4a

4a - 6a = -2a

-2a + 8a = 6a

6a + 3a = 9a

-12 + 8 = -4

Answer

9a - 4

Determine the holes, vertical asymptotes, and horizontal asymptotes of the rational function y=3x^2+10x-8/x^2+7x+12
kompoz [17]
There would be a hole when x = -4.

If you factor both the top and the bottom, you will see that the factor (x + 4) is in both the numerator and denominator. Therefore, the would be a hole when x = -4 because that would also make the denominator 0.
