Area: 78.5 inches squared
Circumference: 31.4
y=2/3x-2
Explanation:
The equation of a line can be written as y=mx+c
m=slope and c = y-intercept
The point at the x−intercept has coordinates (-3,0)
In y=mx+c
0=2/3(3)+c
0=2+c
-2=c
The equation is y=2/3x-2
4x+30
4x equals how many months you go
30 is the fee that comes with the monthly fee
function rule describes the amount of profit that will be made by the student council on the shirt sales is
.
<u>Step-by-step explanation:</u>
Here we have , student council at Smith Valley High School is planning to sell t-shirts as part of a fundraiser using company A, the shirts cost $4.50 each. The student council has to pay the shirt company a design fee of $45. the shirts will be sold for $12 each. We need to find a function rule describes the amount of profit that will be made by the student council on the shirt sales . Let's find out:
Each shirt cost $4.50 . The student council has to pay the shirt company a design fee of $45. the shirts will be sold for $12 each , So the total amount of t shirt he sell is :
⇒
, where x is the number of t shirts !
Now , expenses is given by :
⇒
, where x is the number of t shirts !
So , Profit made is :
⇒ 
⇒ 
Therefore , function rule describes the amount of profit that will be made by the student council on the shirt sales is
.
