Step-by-step explanation:
A. 3n = 33
n = 33/ 3 = 11
B. 9 + w = 10
w = 10 - 9 = 1
C. r - 15 = 30
r = 30 + 15 = 45
D. 2y + 3 = 11
2y = 11 - 3
2y = 9
Y = 9/2
Answer:
y = abs (x-5) -4
Step-by-step explanation:
We are shifting the absolute value function
f(x) = |x| to
g(x) = | x +h| + k
where h is a shift left if h > 0
right if h < 0
and k is a shift up if k> 0
down if k< 0
Since the graph is shifted down and to the right
k is <0 and h < 0
where k = -4 and h=-5
You calculate it by taking the change in y's over the change in x's. So (y1-y2)/(x1-x2). You get the equation (-5 - 3)/(5 - 7) which equals 4. 4 is the slope.
diameter 22 equals radius of 11
Area = PI * radius^2 = PI * 11 * 11
Area = 380.1327110844
