You would take the amount of increase and divide it by the amount of total cost over the time period of certain months. Then you would multiply that number by the percentage of increase gained, and subtract 96.12 to get your answer.
Step-by-step explanation:
15X - 4Y when X=7 Y=8
=15*(7) - 4*(8)
= 105 - 32
=73

X=5 and Y = 8
Because 5 times 8 equals 40 and -6 times 5 equals -30 so 40-30 equals 10 and 10-10 equals 0
Answer:
1, 3, 4, and 10
Step-by-step explanation:
To get a y value, substitute the x value into the equation they gave you (y = 3x - 5). For the x value 2:
y = 3(2) - 5
y = 6 - 5
y = 1.
To get a missing x value, solve for x in the equation they gave you. You were given the y value, so you can substitute that into the equation.
(4) = 3x - 5
Add 5 to both sides
9 = 3x
Divide both sides by 3
3 = x
Do the same with 7
(7) = 3x - 5
Add 5
12 = 3x
Divide by 3
4 = x
For the last one, you're given x so substitute it into the equation:
y = 3(5) - 5
y = 15 - 5
y = 10
