y=1 is the answer, there is no slope, so the formula y=mx+b turns into y=b, since 1 is the intercept 1 is b.
we know that
surface area of the cylinder=2*{area of the base}+perimeter of base*height
area of the base=pi*r²
r=40 ft
Area of base=pi*40²
Area of the base=1600*pi ft²
Perimeter of the base=2*pi*r
Perimeter of the base=2*pi*40
Perimeter of the base=80*pi ft
surface area of the cylinder=2*1600*pi+80*pi*17
surface area=4560*pi ft²
therefore
the answer is the option
4560π ft2

I took the test
Answer:
y=150+50x
Step-by-step explanation:
Given data
Repair= $150
weekly charge = $50
X=#of weeks and y=total cost.
Hence the expression in slope-intercept form is
y=150+50x
Answer: 10x + 7
Step-by-step explanation:
multiply everything
2x + 7x + x + 7
combine like terms
10x + 7
