The answer is f(x) I’m not quite sure what
Answer:
Because you know the equation for what x equals, you can plug that equation into the x of the second equation.
For example: 3(16-4y)+4y=8.
Then you can solve for y. After you find y, you will plug that number into the original equation (x=26-4y) and solve for x.

Answer:
the volume of the solid is
Step-by-step explanation:
Given the data in the question;
y = x and y = x²
so
x = x²
x - x² = 0
Radius will be; r = ( x - x² )/2
Area of the circular disk πr² = π[ ( x - x² )/2 ]²
A = ( x - x² )²
So, our volume will be;
V = ₀∫¹ A(x) dx
we substitute
= ₀∫¹ ( x - x² )² dx
{ lets expand; ( x - x² )² = x(x-x²) -x²(x-x²) = x² - x³ - x³ + x⁴ = x² + x⁴ - 2x³ }
so we have;
= ₀∫¹ ( x² + x⁴ - 2x³ ) dx
= + -
= [ + - ]
= [ ]
V =
Therefore, the volume of the solid is
