(22,12) m=4
y=mx+b
12=4*22+b
12=88+b
subtract 88 from each side
b=-76
y = 4x-76
subtract 4x from each side
-4x+7 = -76
Choice A
If we are to choose any number from 100 to 500, you may take any other number but for the purpose of showing how things are done here, let me choose 100 gallons. Similarly, we choose 2 gallons to be drain out each day.
The equation that would best represent the relationship between the given parameters is,
y = 100 - 2x
where y is the volume of water after x days.

Answer:
3x = 14
Step-by-step explanation:
Add the two equations.
5x + (-2x) = 3x
(-y) + y = 0
6 + 8 = 14
3x = 14.
Answer:
1st answer: 729
2nd answer: 625
3rd answer: 10,000,000
Step-by-step explanation:
3 to the power of 6= 3x3x3x3x3x3 = 729
5 to the power of 4= 5x5x5x5 = 625
10 to the power of 7= 10x10x10x10x10x10x10 = 10,000,000
