1.An advertising company charges $40 per half-page advertisement and $75 per full-page advertisement. Michael has a budget of $800 to purchase 13 advertisements. Write a system of equations and show me how you broke it down

H + F = 13

40H + 75F = 800

He can purchase 8 full-page advertisement and 5 half-page advertisement

Step-by-step explanation:

Let H = half-page advertisement and F= full-page advertisement.

The total amount of advertisements that Michael can buy is:

If each H costs $40 and each F costs $75, the total amount spent by Michael is:

Both equations give us the following system:

Solving the linear system:

He can purchase 8 full-page advertisement and 5 half-page advertisement

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
