AnnZ [28]

Answer:

B. 6x²-6x

Step-by-step explanation:

If the sum of two binomials is 9x²-4x, and we know that one of them is 3x²-2x, we must subtract 3x²-2x from 9x²-4x to find the second binomial.

9x²-4x-3x²-2x

Combine like terms

6x²-6x

Plz help I am going to get my phone took away because I am failing math

80 is the total number of students
Total cost: $10/student x 80 = $800
                 $960 x 2 = $1,920
In order to get the total cost per student, we need to get the sum of the cost of the food and bus rental. So 800 + 1,920 would be $2,720.
Now, divide the sum by 80 (number of students) and the result is 34. So the total cost per student is $34.

Carson is a salesman at an insurance company. He receives a monthly salary of $1,011.00 and a $168.00 commission on each policy
LiRa [457]

Answer:

f(x)=1,011+168x

Step-by-step explanation:

f(x) represents the total pay, so put that on one side of the equation. The total amount is the salary check and the commissions check, so you need to add those. So far, we have:

f(x)=1,011+168

He is payed $168 per policy, so we need to multiply the amount of policies sold by the pay per policy. Since we don't know how many policies he sold, we use x to represent the unknown number of policies:

168*x\\168x

Insert into the equation we made before:

f(x)=1,011+168x

Done.
