3 0

Answer:

f(g(-1)) = -3

Step-by-step explanation:

g(-1) = -1² - 7(-1) - 9

g(-1) = 1 + 7 - 9

g(-1) = 8 - 9

g(-1) = -1

f(g(-1)) = -1 - 2

f(g(-1)) = -3

In the parallelogram below find why
Mkey [24]
Angle E=130degrees because those two are congruent. Therefore if you 180-130 you'll get the other angle in the triangle with 70degrees and y. 180-130=50degrees. Then add 50 and 70. 50+70=120degrees. A triangle is supposed to have 180 degrees inside.
180-120=60degrees.
Therefore y=60degrees
