Help please if you can? If f(x) = -2x - 5 and g(x) = x^4 what is (gºf)(-4)

Answer:

81

Step-by-step explanation:

g(x) = x^4                     put f(x) in for x in g(x)

g(f(x)) = (f(x))^4             Substitute the value for f(x) which is (-2x - 5) put - 4 in for the x in f(x)

g(f(x) = (-2x - 5)^4

g(f(x)) = (- 2*(- 4) - 5)^4  Combine

g(f(x)) = (8 - 5)^4             Subtract

g(-4) = (3)^4                    Raise 3 to the 4th power

g(-4) = 81                        Answer.

PLEASE HELP ME ASAP!!!!! I ONLY HAVE 2 ATTEMPTS LEFT!!!!
Simora [160]

Answer:

m∠1 = 105°

m∠2 = 75°

Step-by-step explanation:

Lines a and b are parallel.

1. Angles 1 and 75° are the same side angles when two parallel lines a and b are cut by transversal t.

The same side angles add up to 180°, so

m∠1 + 75° = 180°

m∠1 = 180° - 75°

m∠1 = 105

2. Angles 2 and 1 are supplementary (add up to 180°), then

m∠1 + m∠2 = 180°

m∠2 = 180° - 105°

m∠2 = 75°
