Answer:
Step-by-step explanation:
Slope: -3
y-intercept: -2 (y-intercept is where a line cross the y-axis, vertical line)
Pencil on the y-intercept, three down and one to the right, then trace the line from -2 on the y-axis.
Setup is
y = k/x
8 = k/3
k = 24
Now use 6 for y
6 = 24/x
x = 24/6 = 4 or A
Answer:
<h2>
k = 31/9</h2><h2>
b = 12</h2>
Step-by-step explanation:
<u>k - 4</u> = 3
9
k/9 = 3(9) + 4
k = 31/9
k = 31/9
<u>8 + b </u> = -5
-4
8 + b = -5 (-4)
8 + b = 20
b = 20 - 8
b = 12
Answer and Step-by-step explanation:
If the radius is 5, then we can plug 5 into the area of a circle equation.
A = 
A = 
A = 25
<u>The area of a circle with radius 5 is 25</u><u>.</u>

Answer:
200 miles
Step-by-step explanation:
First, set up the equations.
plan 1: initial fee of $55.96, $0.12 per mile
plan 2: initial fee of $63.96, $0.08 per mile
We want to know at what distance will the cost be the same. So, set the equations equal to each other.
0.12x + 55.96 = 0.08x + 63.96
Combine the variables.
0.04x + 55.96 = 63.96
Combine the constants.
0.04x = 8
Divide by 0.04 to isolate x.
x = 200 miles
Check by plugging x back into each equation.
y = 0.12(200) + 55.96
y = 24 + 55.96
y = $79.96
y = 0.08(200) + 63.96
y = 16 + 63.96
y = $79.96
You are correct!
