kakasveta [241]3 years ago
5 0

Answer:

A solution point is (2,2)

Step-by-step explanation:

Graph the lines. If it is just greater that or less than, use dashed lines. I fits greater than or equal too, or other symbols like that, use a solid line

Use the test point (0,0). If it satisfies the inequality, shade the side of the graph with that point (you can use any test point, not just (0,0)). If it doesn't satisfy, then shade the other side

The Shaded area shared by both lines is the area of the solution

Answer:

1. f(4) or f(n)= 28

2. f(-2) or f(n)= -2

(please consider marking brainliest <3 )

Step-by-step explanation:

n=4                           n=-2

f(n)= 5(n)+8              f(n)= 5(n)+8

f(n)= 5(4)+8              f(n)= 5(-2)+8

(n)= 20+8                 f(n)= -10+8

f(n)=28                      f(n)=-2

ololo11 [35]

Answer:

$15.71

Step-by-step explanation:

They have already raised $218.25.

$483.62 - $218.25 = $265.37 left to raise

There are 17 students, so the remaining amount can be divided between them.

$265.37 ÷ 17 students = $15.71 that each student needs to raise

You can check this by multiplying $15.71 by 17.
