Equation: 99 + 45x, with x as how many ever months.
After five months:
99 + 45(5) = 99 + 225 = $324.
Using substitution:
4x+2y=12
y=8x+1
4x+2(8x+1)=12
distribute
4x+16x+2=12
combine like terms
18x+2=12
subtract 2 from both sides
20x=10
divide each side by 20
x=10/20
reduce
x=1/2
plug in x for the y= equation
y=8(1/2)+1
multiply
y=4+1
add
y=5
answer:
(1/2,5)
Since the radius is 12, the equation is
.. x^2 +y^2 = 144
Step-by-step explanation:
9$ x 71 hours (rewritten) 9x 71 = 639
plus the commission
10% x 1,901$ (rewritten) .1 x 1,901 = 190.1
639 + 190.1 = 829.1
