Answer:
A (5 -1/2x )^ 1/5
Step-by-step explanation:
y=-2x^5 + 10
Exchange x and y
x=-2y^5 + 10
Solve for y
Subtract 10 from each side
x-10 = -2y^5
Divide by -2
x/-2 -10/-2 = -2/-2 y^5
-1/2x +5 =y^5
Take the 5th root on each side
(-1/2x +5)^ 1/5 = (y^5)^1/5
(-1/2x +5)^ 1/5 = y
Answer:
The answer is 147
Step-by-step explanation:
12x+3 x=12
12(12)+3
144+3
147
Answer:
x = ± 2
Step-by-step explanation:
Given
16 - 2x² = - 64 ( subtract 16 from both sides )
- 2x² = - 80 ( divide both sides by - 2 )
x² = 40 ( take the square root of both sides )
x = ±
= ±
= ± 2
