Answer:
Option (b) is correct.
The profit from sales if the price of the T-shirts were $15 a pieces is $28.
Step-by-step explanation:
Given : The function 
is used to determine the profit on T-shirts sold for x dollars.
We have to find the profit from sales if the price of the T-shirts were $15 a pieces.
Consider the given profit function
For the profit, if the price of a t-shirt is $ 15
Put x = 15, we have,
Simplify, we have,
Also, 
Thus, we get, The profit from sales if the price of the T-shirts were $15 a pieces is $28.
Answer: D. 9.4 units
Explanation: We use the Pythagoras theorem because we know that it’s a right triangle and we have 2 lengths.
8^2+5^2= c^2
89=c^2
c= sqrt 89
c≈9.4 units
64+(2x)=35(x-1)
expand
64+2x=35x-35
minus 2x from both sides
64=33x-35
add 35 to both sides
99=33x
divide both sides by 33
3=x
the number is 3
Answer:
Step-by-step explanation:
we have
Solve for a
That means ----> Isolate the variable a
Factor 3 in the numerator right side
Simplify right side
subtract a both sides
subtract 1 both sides
Rewrite
Answer:
Yes this is a linear function f(x) = ex+30
e = hourly rate
x=hours
f(x) = total earnings
