Answer:

See explanation.

Step-by-step explanation:

We need a point and a slope to have a point slope equation.

$y-y_{1}=m(x-x_{1})$

We need a slope and y-intercept to write in slope intercept form.

$y=mx+b$

A) $y-1=\frac{1}{2}(x+4)$ or $y=\frac{1}{2}x+3$

B) $y+1=-1(x-2)$

C) $y-1=0(x-1)$

D) $y=-3x+8$

1/2x-9=-25 what is your answer

Elodia [21]

First, let's only the expression with x stay on the let side: let's add 9 to both sides of the equation.

$\frac{1}{2} x-9+9=-25+9$
which is
$\frac{1}{2}x=-16$

now, let's multiply everything by 2:

$\frac{2}{2} x=-16*2$
$x=-32$

so the answer is -32!

Can someone help me with this? I don’t need an explanation I just need the answer thank you :)

Answer:

87.92 in²

Step-by-step explanation:

pi × (R² - r²) = area

Where R is the radius of the outer circle and r of the inner circle.

Since C = 2pi×r

37.68 = 2×3.14×r

r = 6 in

R = 6 + 2 = 8 in

Therefore,

pi × (R² - r²) = area

Area = 3.14 (8² - 6²)

= 87.92 in²
