Answer:
m<a = 77
m<b= 103
Step-by-step explanation:
m<a+m<b = 180(supplementary angles)
3x/8+50+x+31=180
3x/8+x+81=180
(3x+8x)/8=180-81
3x+8x=99*8
11x=792
x=792/11
x=72
now
m<a=3x/8+50
=(3*72)/8+50
=77
m<b=x+31
=72+31
=103

Answer:
f(g(2)) = -11
Step-by-step explanation:
f(g(2))=
First we need to find g(2)
g(x) = 3x-4
We let x=2
g(2) = 3(2) -4
6-4
=2
Now we stick the value of g(2) in for x in f(x)
f(x) = -2x^2 - 3
f(2) = -2(2)^2 -3
=-2 (4) -3
= -8 -3
=-11
Answer:
- 5/3
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -1 -9)/(4 - -2)
= (-1-9)/(4+2)
= -10/6
- 5/3
