Answer:
Step-by-step explanation:
So first, lets solve for the intercepts.
Let’s start by finding the x intercept.
Plug in 0 for y.
10x+9(0)=-90
10x=-90
X=-9, so your first point on your line will be (-9,0).
Now the y intercept.
Plug in 0 for x.
10(0)+9y=-90
9y=-90
Y=-10, so your second point on your line will be (0,-10).
Use those points to create your line.
Y = 3x + b
Now plug in points
-7 = 3(-1) + b
-7 = -3 + b
b = -4
The y intercept is -4
What fractions? I see nothing...Do you have the choices?
Circumference = πD
30π = πD
D = 30 inches
Answer: 30 inches
