Answer:
(g◦f)(x) = 2x +1
Step-by-step explanation:
(g◦f)(x) = g(f(x)) = g(2x -1) = (2x -1) +2
(g◦f)(x) = 2x +1
__
Substitute f(x) for the argument in the function g(x) and simplify.
You would substitute or plug in -5 wherever there is an x in the equation.
f(-5) = 6(-5) + 7
f(-5)= -30 + 7
f(-5) = -23
3x+x+20 = 180
4x = 180-20
4x = 160
x = 40
×+20+3x+2x+38+C=360
40+20+3×40+2×40+38+C=360
40+20+120+80+38+C=360
298+C=360
C=360-298
C =62°
Answer:
yes because |x+y|=|x|+|y| is just the same equation just splitting the numbers
They both are the same absolute value equation
Step-by-step explanation:
|x+y|=|x|+|y|
x+y=|x|+|y|
x+y=x+y
