The best way to do this question is to use elimination. Elimination is a way to find out the POINT OF INTERSECTION between two lines. Let me show you how.
3y+4x=3
x+3y=-6
Elimination is a way to remove any same variable with the same coefficient. In this case, there is 3y in both equations. In this case, we subtract to eliminate.
3y-3y+4x-x=3+6 It's plus 6 because two negatives become positive.
3x=9 Divide both sides by 3
x=3
Now you can find y.
x+3y=-6
3+3y=-6
3y=-9
y=-3
Therefore, the POI is (3,-3). I hope you understand this. Make sure to mark as brainliest.
Answer:
im looking at B! hope this helps!
Step-by-step explanation:
Well, what's the graph of say y = 5x - 2?
the line will come by graphing that, y = 5x - 2... then we check the points that lie on either side of the line.
for example... the point (0,4) is a point that lies on the left-hand-side of that line..... so... let's check for its true/false value
(0, 4) x = 0, y = 4
y < 5x - 2
4 < 5(0) - 2
4 < 0 - 2
4 < -2 <--- now, is that true? is 4 lesser than -2? well, nope
so, that means the region where 0,4 lies, is the FALSE region, and we do not shade that part, so the part that needs shading is the other side.
The boundary line is dashed, meaning, it DOES NOT include the points lying on that line, but just anything off that, because y < 5x - 2, means "y" is less than, NOT EQUALS OR LESS, but just less.

Answer:
a) 10
b) The $40+5 dollars for every ticket
c) See below
Step-by-step explanation:
a)
1. Let t=number of tickets
2. Writing an equation
Breaking even means that you earn the same amount of money for both.
40 +5t=70+2t
3. Solving the equation
40 +5t=70+2t
5t-2t=70-40
3t=30
t=10
So the answer to a) is 10.
b)
1. Using an equation
We already know that there are 2 equations for this problem. (40+5t, 70+2t)
So, we will substitute 20 for t.
40+5*20=40+100=140
70+2t=70+2*20=110
2. Comparing equations
140>110, so the first offer is better
C)
The owner lets you choose how you get paid because one option will be better for you, as some days you might not sell many tickets (so you will go with the $70+2 tickets), or some days you might sell many tickets (you will choose the $40+5 dollars/ticket).
