I got $6.22 for the cat food.I'm sure you don't need to know this, but the 4% sales tax is $0.82.

In this question it is important to note down all the important information's that are mentioned in the question.
Cost of a container of cat liter = $13.75
Cost of a bag of cat food = X dollars
Total amount of money required to purchase the items = $20.80
Percentage of sales tax that had to be given = 4%
Then
Amount of sales tax given = (4/100) * 20.8 dollars
                                           = 20.8/25 dollars
                                           = 0.83 dollars
Then the total purchase price for the two items = 20.80 - 0.83 dollars
                                                                            = 19.97 dollars
Now we can easily find the cost of the cat food by subtracting the cost of the liter from the total purchase amount.
Then
Cost of the cat food = 19.97 - 13.75 dollars
                                 = 6.22 dollars
So the cost of the bag of cat food is $6.22

a line with the slope of -5 passes through the points (-3, -5) and (-4, teat parentheses. What is the value of t​
Setler79 [48]

Step-by-step explanation:

First, find the slope using the slope formula

m = (Y2 - Y1)/(X2 - X1).

Then use the point slope formula,

Y - Y1 = m(X - X1), with one of the given

points and the slope. Also, solve for y.

Use Y - Y1 = m(X - X1)

Also, solve for y.

Find the slope of the given line, m, by rewriting the given equation in y = mx + b. Flip and change the sign on the given slope to find the new slope.

Use Y - Y1 = m(X - X1)

Plug in the given point and new slope

and solve for y.

Plot points or graph line. Move a vertical line across the graph. If the line touches more than once then it is not a function.

Domain = { x-values, ... }

Range = { y-values, ... }

List the elements in increasing order and don't repeat.

For this class, the domain is all real numbers unless you have an x in the denominator of a fraction.

When x is in the denominator, set the denominator equal to zero and solve. Everything on a number line works except the value(s) you got when solving.

Answer: (- infinity, #) u (#, infinity)

Parentheses everywhere b/c the number # does not work in the equation.

Domain: Squish the graph to the x-axis. Write shaded part in interval notation (left, right)

Range: Squish the graph to the y-axis. Write shaded part in interval notation (down, up)

Brackets include points, parentheses don't. Infinities always get parentheses.

Write both equations in the style y = mx + b.

Look at the slopes, m, to answer the question.

If the slopes are the same, then they are parallel.

If the slopes are negative reciprocals, then they are perpendicular. Otherwise, neither.

If you have an equal to under the inequality, then you have a solid boundary line. If you don't have an equal to under the inequality, then you have a dotted boundary line.

After you have graphed the boundary line and determined if it is solid or dotted, find a test point on either side of the boundary line. Substitute the ordered pair into the original inequality. If it simplifies down to a true statement, shade the region where that point is. If it is false, shade the region that does not contain that point.

What is the greatest common factor of the numerator and denominator of the rational expression below? 5x-20/x^2-2x-8
OleMash [197]
Factories both equations:
5(x - 4) / (x + 2)(x - 4)

Then take out the common brackets:
5 / x + 2

Minus 2 from both sides:
3 / x

If you are looking for the greatest common factor of the numerator and denominator, the answer would be (x - 4)

As a salesperson, you are paid $50 per week plus $2 per sale. This week you want your pay to be at least $100. What is the minim
DENIUS [597]
Let s represent the number of sales, and t the total pay
the equation to represent this situation is t = 2s + 50
so set t to 100, and solve for s

100 = 2s + 50
50 = 2s
25 = s

you need to make at least 25 sales
