Answer:
Step-by-step explanation:
y = x² - 10x + 27
y = ax² + bx + c
This is the general form of the equation for a parabola.
We must convert it to the vertex form
y = (x - h)² + k, where (h,k) are the coordinates of the vertex.
We can do this by completing the square.
The figure below shows that your parabola has its vertex at (5,2).
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 .
