Answer:
-54, 162, -486
Step-by-step explanation:
You multiply the number in front by -3.
2*-3=-6
-6*-3=18
18*-3=-54
-54*-3=162
162*-3=-486

All you have to do is substitute the y value from the 1st equation into the second equation and solve...
a) y= 2-x
5x + 4y = 5
Substitute (2-x) into the second equation anywhere there is a y...
5x + 4y = 5
5x + 4(2-x) = 5
Now solve
5x + 8 - 4x = 5
5x - 4x + 8 = 5
x + 8 = 5
x = -3
Now that you have a solution for x, substitute -3 into either of the original equations anywhere there is an x then solve for y...
y = 2 - x
y = 2 - (-3)
y = 2+3 = 5
You solved for x and got -3 and solved for y and got 5, so your solution set is
(-3, 5).
Now check it by substituting both numbers into one of the original equations and you should have a true statement if it is correct...
y = 2 - x
5 = 2 - (-3)
5 = 2+3
5 = 5
True statement... it checks!
note* during the check, if the equation would have worked out to something like 2 = 5, then that is a false statement therefore the solution set would be wrong and you'd have to go back and find the mistake.
Answer:
A
Step-by-step explanation:
Table:
it says that x is the amount of tickets, so that would be 1, 2, 3, etc.
It says that y is the money spent and also tells us that one ticket is $3, so obviously the money would be increasing by thirds: 3, 6, 9
This all goes with the first table (table A)
Graph:
As for the graph-
X = # of tickets (1, 2, 3)
Y = $ spent (3. 6, 9)
The answer would be graph A, because when looking at it you can tell that the starting point is at $0 for 0 tickets, unlike for graph b, which shows $3 for 0 tickets, which does not make any sense. But when you continue on when graph A, you can tell that this answer choice is correct, because every time, the y value is 3 times the x value which means: y=3x
