Answer:
f(7) = 22 or x =2
Step-by-step explanation:
- f(x) = 3x + 1
- f(7) = 3(7) + 1
- f(7) = 21 + 1
- f(7) = 22
<u>Or if the equation meant it like this:</u>
- f(x) = 3x + 1
- 7 = 3x + 1
- 6 = 3x
- 2 = x
Step-by-step explanation:
(x−1)²−9=0
(x-1)²= 9
x-1 = ±√9
x-1 = ±3
x = 1-3=-2 or x=1+3=4
the solution = {-2,4}
Answer:
=26x^3−12x^2+5x+7
Step-by-step explanation:
2x^3−3x+11−(3x^2+1)(4−8x)
Distribute:
=2x^3+−3x+11+24x^3+−12x^2+8x+−4
Combine Like Terms:
=2x^3+−3x+11+24x^3+−12x2+8x+−4
=(2x^3+24x^3)+(−12x^2)+(−3x+8x)+(11+−4)
=26x^3+−12x^2+5x+7
