Step-by-step explanation:
just guess and see
F(g(x))= 2(g(x))+5 = 2(x-7)+5 = 2x-14+5 = 2x-9
when x= -3
f(g(-3))= 2(-3)-9 = -6-9 = -15
Complementary angles = 90°
Subtract 36 from 90 to get the measure of the other angle
90 - 36 = 54
Answer = 54°
_____________________________________________________________
Supplementary angles = 180°
Subtract 115 from 180 to get the measure of the other angle
180 - 115 = 65
Answer = 65°

Answer:
x= -2, x= +11
Step-by-step explanation:
I hope this is right!
To factorise, we need two numbers that add to make -9 and multiply together to make -22.
2 - 11 works, so we put it in the brackets in this order.
(x + 2) (x - 11)
so x + 2 = 0 and x - 11 =0
but we could also simplify this to say that x could be either -2 or + 11.
I hope this helps.
Have a lovely day.
