▹ Answer

(x₁, y₁) = (-7, -5)

(x₂, y₂) = (2, 13)

▹ Step-by-Step Explanation

y = x² + 7x - 5

y = 2x + 9

Make the sides equal

x² + 7x - 5 = 2x + 9

Solve

x = -7x

x = 2

Substitute

y = 2x(-7) + 9

x = 2

Solve

y = -5

y = 2 * 2 + 9

Solutions

(x₁, y₁) = (-7, -5)

(x₂, y₂) = (2, 13)

Hope this helps!

Answer:

105

Step-by-step explanation:

$A=lw$ $A=$ (.5)πr²

to get the area of the shaded parts you have to subtract the area of the semicircle from the area of the rectangle

$A=(16)(9)$

$A=144$

$A=\frac{(3.14)(5)^2}{2}$ $A=\frac{(3.14)(25)}{2}$ $A=\frac{78.5}{2}$

$A=39.25$

subtract the areas

$144-39.25=104.75$

$104.75$ ≅ $105$
