Step-by-step explanation:
14-2=12
12÷3=4
Answer=4
Are you asking how much money was added? Because if you are then you would just subtract and get 25
X = 1 - y & 3x = 8 - 5y ; Find x
Plug in x into the second equation.
3x = 8 - 5y
3(1 - y) = 8 - 5y
Simplify.
3 - 3y = 8 - 5y
Add 5y to both sides.
3 - 3y + 5y = 8
Subtract 3 from both sides.
-3y + 5y = 8 - 3
Simplify.
2y = 5
Divide both sides by 2.
y = 5/2
Now, since you have the value of y, you simply plug y into the first equation.
x = 1 - y
x = 1 - 5/2
Simplify.
x = 1 - 2 1/2
Simplify.
x = -2/2 - 5/2
Simplify.
x = -7/2 AND -3 1/2

Step-by-step explanation:
Answer:
The given table is
Quantity(x) Price(y)
1 2.00
2 3.50
3 5.00
4 6.50
5 8.00
6 9.00
It means the points on the graph are (1,2), (2,3.50), (3,5), (4,6.50), (5,8) and (6,9).
The graph 1 represents all the above mentioned point, therefore option 1 is correct.
According to the graph 2, at quantity 6 the price of flower is 12, which is not correct. Therefore option 2 is incorrect.
The quantity of flower is always a whole number. So the graph is defined on the whole numbers only. It means the graph is a scatter plot instead of a curve of a straight line.
Therefore the option 3 and 4 are incorrect.
