4(2x)=8x
4(3)=12
8x+12=75
-12
8x=63/8
x=7.89
The x-intercepts are 
The y-intercepts are 
Explanation:
The relation is 
To find the x-intercept, let us substitute
in the equation
, we get,

Thus, the x-intercepts are 
To find the y-intercept, let us substitute
in the equation
, we get,

let us switch sides and solving, we get,

Taking square root,
and 
Thus, the y-intercepts are 
Answer:
$6,600
Step-by-step explanation:
231/0.035= 6,600
Without needing the distance formula
from 4,1 to 0,1, you move the "x" from 4 to 0, over the same "y" value of 1, so is just 4 units long, from the center to an endpoint, and the chord that stems from the center to an endpoint is the radius, so r = 4
