Answer:
I think it is 37.5°.
Step-by-step explanation:
X-9=12
x-9+9=12+9
You need to add 9 to each side of the equation.
x=21
Mulitpilicty is how many times a root repeats
factor
factor x first
x(2x^2+x-1)
using math
(x)(x+1)(2x-1)
no roots repeat
if it is equal to 0 then the roots are
0 multiplicty 1
-1 multiplicty 1
1/2 multiplicty 1
X is left and right
hmm
see the aproximate slope
see endpoints
ok, so from about (0,3) to (35,30)
slpoe is 27/35
so
y=(27/35)x+3 about
so when x=
ok, so according to the garph, when x=35, y=30, not 20
ok, so when x=40
y=(27/35)x+3
y=(27/35)*40+3
y=33.8571 about for x=40
