Answer:
A. 9 in
Step-by-step explanation:
The diameter of the circle is 18 in. The radius is half the diameter of the circle.
d= 18 in
r= 18/2
= 9 in
Answer:
y = 3x - 1
Step-by-step explanation:
The slope of a line passing through the two points
P = (x1. y1) and Q = (x2, y2) is given by
m= (y2-y1)/(x2-x1)
We have that x1= -6, y1= -19, x2= 2, y2= 5
m=3
Now, the y-intercept is b=y1 - mx1 (or b= y2 - mx2, the result is the same).
b= -19-(3)(-6)
b= -1
y = 3x - 1
To find f(-7), just plug -7 in for all x
2(-7) + 8
-14 + 8
-6 is the answer!
