Answer:
.85p + 1.45m <= 14
Step-by-step explanation:
You don't want to spend more than 14, but you can spend 14. So the inequality must be less than or equal to. To find the combination of pencils and markers you must multiply their price times the number of pencils. Sorry if this explanation isn't amazing, I know how to do work but not explain my reasoning. :)

Answer:
one solution : (2 ; 3)
Step-by-step explanation:
hello :
4x + 5y =23
...(*)
9x- 5y= 3....(**)
add (*) and (**) : 13x =26
x =26/13 = 2
put this value in (*) : 4(2)+5y = 23
5y =15
y =15/5=3
one solution : (2 ; 3)
Answer: -11
Step-by-step explanation:
For this problem, it is important to look at the domains next to the function. In this problem there is a function for when x < 1 and when x ≥ 1. 3 is greater than 1, so we will use the second equation.
From there, plug in 3 for x and solve.
-2x - 5
-2(3) - 5
-6 - 5
-11
