Answer:
y = 2x + 4
Step-by-step explanation:
First find 2 points on the line to determine slope.
(0, 4) and (2, 8)
Slope = 
y = 2x + b
b = y - intercept
b = 4
y = 2x + 4
Answer:
A = 157 in^2
Step-by-step explanation:
First, we need to get the radius, we can do this by dividing our given diameter by 2.
20/2 = 10
Now, we have our radius of 10 inches.
Formula for Area of a Semi Circle: (1/2)(pi(r^2)
Input values.
(1/2)(3.14(10^2)
Solve.
(1/2)(3.14(100)
(1/2)(314)
1/2(314) = 157
Finally, we have our result which is 157 inches^2.
You would have to solve for x the plug in the answer for c into the next equation to find your answer
Answer:
21 & 22
42.25 ÷ 2 = 21.125.
21.125 rounded to the two nearest whole numbers is 21 and 22.
21 and 22 are the closest integers to 21.125.
The answer is 21 and 22.
Hope it helps!
