Answer:
19/3 or 6.33 continuing
Step-by-step explanation:
using pemdas, do the exponent first
6-2=4
then multiply by 4
4x4 is 16
add 3^2 to this, which = 9
so 16+9-6 is on top which equals 19, this is over 3
so 19/3
Have you learned PEMDAS? (Parenthesis, exponents, multiplication, division, addition, subtraction). That is what I am going to do here.
The first parenthesis, let's solve. 7*10=70-5=65
The second parentheisis: I am assuming the negative sign is a typo, and this answer will be off if it is not. Sorry. 5*10=50
65*50=3250
I hope this helps, and let me know if you need further assistance.
Answer:
A
Step-by-step explanation:
The function is f(x) = 15x + 25 as 25$ is a fixed rate ( it does not change and is always charged) when 15$ for any other service which can be anything, a costumer can have 0 services other than the hair cut which gives f(0). As for the question, it's asking for haircut, shampoo, highlight, and blow dry so that is 3 other services other than the fixed haircut which means f(3). substitute x=3 in the function to get 15(3) + 25 = 45+25 = 70.
The function of x is equal to 7 dollars times the number of hours the cashier works. This function would look something like this:
F(x) = 7x
Hope this helps! :)
