What is a linear equation in math?
- A linear equation only has one or two variables.
- No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
- When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
Suppose, time taken by faster maid be x , hours.
So, time taken by slower maid ,
( 4 time faster maid )
Now, time taken by both of the made together is given by ,
which is the time required by faster maid.

Answer:
14.99x3=44.97+4.99=49.96. You will have to pay $49.96 for the three CDs plus the shipping charge.
Step-by-step explanation:
Answer:
x = 1 + sqrt(89) or x = 1 - sqrt(89)
Step-by-step explanation:
Solve for x:
(x - 9) (x + 7) = 25
Expand out terms of the left hand side:
x^2 - 2 x - 63 = 25
Add 63 to both sides:
x^2 - 2 x = 88
Add 1 to both sides:
x^2 - 2 x + 1 = 89
Write the left hand side as a square:
(x - 1)^2 = 89
Take the square root of both sides:
x - 1 = sqrt(89) or x - 1 = -sqrt(89)
Add 1 to both sides:
x = 1 + sqrt(89) or x - 1 = -sqrt(89)
Add 1 to both sides:
Answer: x = 1 + sqrt(89) or x = 1 - sqrt(89)
In this function, x represents the number of 2) HOURS WORKED PER WEEK.
Profit is net of the fixed income of 8600 and variable cost of 22 hourly rate times the number of hours worked by the employee.
Example:
If the employee worked for 100 hours, then the profit would be:
P(x) = 8600 - 22(100)
P(x) = 8600 - 2200
P(x) = 6400
Even if the employee works 24 hours for the whole week or 7 days, they will still earn profit.
24 hours x 7 days = 168 hours
P(x) = 8600 - 22(168)
P(x) = 8600 - 3696
P(x) = 4904
