During a clothing store's bargin days, the regular price for t-shirts is discounted to $8.25. you have an additional coupon for $5.00 off, regardless of how many shirts are purchased.

a. write a rule for the function p(t) that expresses the final price of t t-shirts with the discount applied.

b. how much would you pay during bargain days for 11 shirts?

b) The cost of 11 T-shirts during bargain days is $85.75

Step-by-step explanation:

We are given the following information in the question:

Discounted cost of one T-shirt = $8.25

Additional off on coupon = $5.00

Let t be the number of T-shirts bought during the bargain days.

a) Then, the price of t T-shirts with the discount applied will be given by the function:

b) Price during Bargain Days for 11 shirts

We put t = 11 in the above function:

Thus, the cost of 11 T-shirts during bargain days is $85.75

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

uhhh idk u yolo?
