Answer:
y=18.5x
Step-by-step explanation:
74-55.5=18.50
92.50-74=18.50
111-92.5=18.50
(3,55.50)
y=18.5x +b
55.50=18.5(3)+b
55.50=55.50+b
b=0
Answer:
Step-by-step explanation:
-9x^3(x^2 - 4x - 21) =
-9x(x - 7)(x + 3) <===
Step-by-step explanation:
W=N•D
W=(200)(1.3)
W= 260
notice, the circle is missing 1/4, so the area of it is just 3/4 of the whole area of the circle.
