Answer 1

for #4 the solution would be any point in the shaded region

Answer 2

#5 is wrong

Answer 3

so c would be a better choice for #4?

Answer 4

Yeah

Answer 5

ok and could you help with #5 cause i never really got how to graph that

Answer 6

Well , your answer is close for #5, you're just a little off
You can use http://desmos.com/calculator to graph

Answer 7

Answer 8

while calculators can do the graphing for you, they are not very helpful on learning it

Answer 9

oh man, i was close, then it would be I, II, III

Answer 10

for \(\bf y\ge x-2\) you graph the line of y = x-2
then you shade the "true" area,

Answer 11

and that would be above the line

Answer 12

yes

Answer 13

how about #6?

Answer 14

well, using substitution \(\begin{array}{llll}
{\color{brown}{ x}}=y-3\\
{\color{brown}{ x}}+3y=13\implies {\color{brown}{ y-3}}+3y=13
\end{array}\)

what woiuld that give you for "y"?

Answer 15

\[y = 4\]

Answer 16

so then its A

Answer 17

yeap, y = 4
meaning x = y - 3 => 4-3 => 1

Answer 18

# 4 is c...because u have a dashed line...points ON the line r not solutions

Answer 19

\[x = y - 3 \]
\[x + 3y =13\]

x = 1 y =4



1 = 4 - 3
1 + 3(4) = 13

Answer 20

wait so what was number #5 because there's no 1,2,3
