7 is subtracted from a number y. y-7
Then the result is multiplied by 3. 3*(y - 7)
The final answer is less then or equal to 12. 3*(y - 7)≤12
3*(y - 7)≤12
y-7≤4
y≤ 11
you need to make the fraction to 100
100/25=
you multiply 20x4
80
The slope intercept form of the equation of a line is given as:
y = mx + c
where m = the slope of the line
c = the y - intercept of the line
1) Two line are parallel if they have the same slope
That is:

2) Two equations are perpendicular if the slope of one is the negative inverse of the other.

3) Two equations are coincidental if they have the same slope and the same y intercept
Answer: $9.20
Step-by-step explanation:
Divide the full tax price by the sales tax (7% or .07) plus 1 (always add 1 to the tax) thus
$147.66 / 1.07 = $138.00
So $138.00 is the full price without tax.
Now divide $138.00 by the amount of tickets (15) to find a single ticket price before tax!
138.00/15 = $9.20
Remember to always add 1 to the tax percentage above when dividing to get the *pre-tax* price.
