All it is asking is to plug the given x values into the equation (which are 0, 2, 4) and see what you get for y.
4y - 2x =16
4y - 2 (0) = 16
4y = 16
y = 4
4y - 2 (2) = 16
4y - 4 = 16
4y = 20
y = 5
4y - 2 (4) = 16
4y - 8 = 16
4y = 24
y = 6
so D
The original price is $4.50 because when you multiply it by 50% you get $2.25
Answer:
A
Step-by-step explanation:
If you convert the first equation to y=mx+b form, it will be the same as the second equation.
6x - 15y = 15
-15y = -6x + 15
y =
x -1
Because the 2 equations are the same now, they are the same line.
Change the fraction to a improper fraction.
11/9 + 10/9
Since they have the same denominators you can add them.
11/9 + 10/9 = 21/9
The answer is 21/9
Hope this helps :)
