I am sorry, that is not enough information. You have to show us the graph.
Answer:
Rodell only polled fellow athletes; this sample does not represent nonathletes at the school.
Step-by-step explanation
can i pls get brainliest if im right?.
I used the elimination method:
Multiply 9x+4y=7 by 2: 18x+8y=14
Multiply 6x-4y=2 by 3: 18x-12y=6
{18x+8y=14}
{18x-12y= 6}
18x-12y=6
-
18x+8y=14
_____________
-20y= -8
{18x + 8y = 14}
{-20y= -8}
Isolate y
y= 2/5 For 18x+8y=14 plug in y=2/5
Sovle 18x+8(2/5)=14 for x: x=3/5
<u>THE SOLUTIONS FOR THE SYSTEMS OF EQUATIONS ARE:
</u><u></u>y= 2/5, x=3/5
<span>-1<0
so use 2x+1
2(-1)+1=-2+1=-1
-
</span><span>F(-1) means "Evaluate F(x) when x=-1"
Since -1 is less than 0, this means that F(x) = 2x+1. This is because F(x) = 2x+1 when x < 0</span>
