Franklin is 70 years of age since 7 is 10% so 10 x 7 = 70
The line y=7 is a horizontal line with a slope of 0.
Slope intercept form of
y=mx+b
would be
y-y1=m(x-x1)
m=0 and point of (-1,-10)
y-(-10)=0
y=-10
Circumference of the circle is given as = 220 feet
We have to find the diameter.
Circumference is found as = 2 * PI * r


r=35.03
Diameter is 2*radius
Diameter =
= 70.06
Hence, diameter of the circle is 70.06 feet.
Answer is 6(c) + 50
Step by step
We know the following
6 months cable multiplied by “c” dollars per month plus $50 one time fee
6 (c) + $50
We multiply 6 months times the unknown “c” per month. Then we add the one time fee.
The other three options multiply $50 by 6 months, by 2 and by “c”, therefore not correct.
