Answer:
C
Step-by-step explanation:
Given
m + 5 = 17 ( subtract 5 from both sides )
m = 12 ( multiply both sides by 3 to clear the fraction )
2m = 36 ( divide both sides by 2 )
m = 18 → C
Answer:
(eduacted guess) 7 minutes, 30 seconds
Step-by-step explanation:
May not be correct but what I did was find the average of 6 and 9. You add the 6 and the 9 (15), then divide it by 2.
Answer:
x2+5x/2 -4
Step-by-step explanation:
f(x) = 2x+3 and g(x) = x^(2)+(x)/(2) - 7 , what is (f+g)(x)
x^2+5x/2-4
Answer:
the answer is tbh .
Step-by-step explanation:
f(x) =5-3x
g(x)=x²-1
f(g(x)) = f(x²-1)
replacing x by x²-1 in the function f(x) , we get
f(x²-1) = 5-3(x²-1) = 5-3x²+3 =8-3x²
f(g(x)) =8-3x²
now finding g(f(x))
g(5-3x)
replacing x by 5-3x in the function g(x)
g(5-3x) = (5-3x)²-1
g(5-3x) = 5²-30x +9x²-1 = 9x²-30x +24
g(f(x))= 9x²-30x +24
f(g(x)) =8-3x²
in option third the f(g(x)) is -3x³+8 which is incorrect
