Answers
Answer:
The one in the table on the left
Note that for the given values of x all of the y values are 2
This indicates a horizontal line, parallel to the x- axis with a slope of zero.
The equation of the line is y = c where c is the value of the y- coordinates the line passes through, in this case 2, thus
y = 2 is the equation of the line with zero slopeation
one of them is an undefined slope the other is a positive slope (Neither of them are a zero slope)
The slope of the first line is 0, as per slope-intercept form.
What is the slope of a straight line?The linear equation y = mx + c represents the slope-intercept form of a line passing through the point (x, y).
Here, 'm' is the slope and 'c' is the y-intercept of the given line.
The slope of a line that passes through points (x₁, y₁) and (x₂, y₂) is defined as:
m = (y₂ - y₁)/(x₂ - x₁)
Here, the slope of the first line that passes through (- 3, 2) and (-1, 2) is
= (2 - 2)/[- 1 - (- 3)]
= 0/2
= 0
Now, the slope of the second line that passes through (- 3, 3) and (-1, 1) is
= (1 - 3)/[- 1 - (- 3)]
= - 2/2
= - 1

It’s the end of the season, so softball bats are on clearance for an additional 30% off the sales price. Finley finds one in her size: It was originally $70.00, but is marked down to $50.00. How much will the bat cost Finley on clearance?
Answers
50 - (50x.3) = x
50 - 15 = x
35 = x
The sale price of the bat is $35.
The requried, bat will cost Finley $35.00 on clearance with an additional 30% off discount.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
The bat is marked down to $50.00, but with an additional 30% off clearance discount, the final price that Finley will pay is,
Final price = $50.00 - (30% of $50.00)
To calculate the discount, we first need to find 30% of $50.00, which is:
0.30 × $50.00 = $15.00
So the discount is $15.00.
Substituting this value into the equation, we get:
Final price = $50.00 - $15.00 = $35.00
Therefore, the bat will cost Finley $35.00 on clearance with an additional 30% off discount.

Amelia is building 3 square garden beds that are all the same size. She arranges them side-by-side to seperate the certain plants. Amelia wants to know the total area of the garden beds.
s= length (ft) of one side of a garden bed.
there are three garden beds. they are squares.
Write an expression to show the total area of garden beds.
Answers
Answer:
3(s x s)
Step-by-step explanation:
You can find the area of each garden bed by multiplying the length of each square, and since a square has four equal sides, the area of one square would be s times s. S times s equals the area of ONE square, so you would take that area and multiply it by three, since you have three squares. Hope this helps!
Answer:
3(s x s) or 3s^2
Step-by-step explanation:
The formula for area is l x w or length x width. The length and width in this case would be "s" and "s." The variable is "s" because "s" can be any number. There are 3 square garden beds so we have to multiply the s x s equation by 3 which would get us to 3 x s x s.

Franklin is incorrect.

When you multiply a negative number by a positive number, you get a negative number. When you multiply a negative number by a negative number, you get a positive number. Therefore, Henry's product would be greater than Franklin's product.

Answer:
decreased by 220 dollars
Answer:
The value on her gift card decreased by $220 dollars.
Step-by-step explanation:
We don't know what amount she originally had on the card, but we can still find out how much she lost by adding up the prices of the things she bought/rented. First, we need to find the cost of renting the tiller for 6 days, it costs $36 per day, so we need to do 6 times 36, which gives us $216. Then we need to add the $4 for the rake.
$216 + $4 = $220

You have designed an app for students to use at your school. It is an interactive calendar that has all of your school events on it, and it will allow the user to incorporate their schedule in it, assignments, etc. You estimate that about 200 people at your school will purchase the app to use. You are hoping this will give you enough money to buy a new video game system (or iPad, smartphone, etc.) which costs $500. You need to figure out how much to sell the app for so that the 200 sales will give you enough money for your purchase.
1. Write an equation to represent the situation that will allow you to figure out how much you need to charge for your app. Solve the equation.
2. How can you increase the amount of money you get from sales of this app?
Answers
Answer:
(1.) $500.00 divided by 200 = ($2.50)
You can increase the amount of money you earn by adding say, 0.50 cents to $2.50 which equals $3.00 then multiplying 3 (representing $3) by 200 (the amount of people) to get the amount of money you earn.

Answer:
It would be 14 pens for $1.54

Divide 1.28 and 8, you get 0.16
Divide 1.54 and 12, you get 0.11
The 14 pens offers a better unit price of .11 cents per pen, instead of .16 cents per pen.
