Answer:
19, 21, 23
Step-by-step explanation:
x + x + 2 + x + 4 = 63
3x + 6 = 63
3x = 57
x = 19
19, 21, 23
If f(x)=1/9x-2
then f^-1(x) will be
lets assume f(x)=y
y=1/9x-2
y+2=1/9x
9(y+2)=x
f^-1(x)=9(y+2)
rest u can do with the same method
Y = -3x^2 +4 is the answer to this problem
Answer:
(x - 6) (x + 1)
x = 6 and x = - 1
Step-by-step explanation:
x^2 - 5x - 6
-6 +1 = -5 and (-6)*(1) = -6
(x - 6) (x + 1)
x -6 = 0
x = 6 and x + 1 = 0
x = -1
