Answer:
y = 13x - 55
Step-by-step explanation:
So this is what we know
Selling price = $13 per copy
Expenses = $55
The formula for profit in this case is:
Profit = total selling price - expenses
In which y is the profit
The total selling price is 13x. x here is for the number of manuals she sells
The expenses are $55.
This then becomes y =13x - 55

Answer:
y = (-5/7) x + 1
Explanation:
The slope-intercept form of the line has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept
The given is:
5x + 7y = 7
To put this in slope-intercept form, we will need to isolate the y as follows:
5x + 7y = 7
7y = -5x + 7
y = (-5/7) x + (7/7)
y = (-5/7) x + 1
where:
m is the slope = -5/7
c is the y-intercept = 1

Answer: 22.14 (22.1428571429)
Step-by-step explanation:
OK
Let's Start with the equation
0.7(x−7)−4.9=5.7
Add 4.9 to both sides
0.7(x-7)=10.6
Divide both sides by 0.7
x-7= 15. 1428571429
Add 7 to both sides
x= 22.1428571429 or 22.14
