9. Cal is buying T-shirts and shorts. T-shirts cost $12 and shorts cost $25. He plans
on spending no more than $160 and
wants to buy at least 5 items.
a. Write a system of linear inequalities
that represents the situation.
b. Graph the inequalities.

Hey there!

Step By Step:

Well so we know that 12 is about half of an 25. So what we are gonna do is to buy 3 of 12$ and 2 of 25$.

3x12=36 and 2x25=50.

With adding those two last numbers, you’ll get $86.

Graph would be down below.

Hope it helps :D

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
