Which of the following is the sale price for an item with an original price of $9.99 after applying a discount of 35%?
A.$3.50
B.$6.49
C.$9.34
D.$9.64
Answer:
it is b
Step-by-step explanation:
x/9.99=35/100 and if u cross multiply 9.99X35 divided by 100 it is 3.4965 which are the savings so 9.99-3.4965 is 6.4935 so it is b

Calculate the slope of a line that goes through the points: (5, 7) & (2, 7). Leave your solution as a simplified (improper) fraction.
Answer:
0
Step-by-step explanation:
m=(y2-y1)/x2-x1), if m is slope and the 2 points are (x1, y1), (x2, y2).
m=(7-7)/(2-5)
m=0/-3
m=0
also, you don't need to know this but if a line has a slope of zero it's a horizontal line
What is the total cost of a cell phone that costs $97.03 if there is an eight percent sales tax?
Answer: $104.79 (rounded to nearest penny)
Step-by-step explanation: Okay, so you know how you can multiply a number by a percent to get part of that number? Since you have the sales tax, 8%, you could multiply the original price by 8%, or 0.8, to get 7.76 (rounded to the nearest penny)- that's how much you would have to pay extra, since sales tax is an additional cost to your original price. From there you could just add 7.76 to 97.03 to get $104.79.
A shorter way:
Multiply by 108%, or 1.08, since you have to pay 100% of the cost plus an additional 8%. That will give you that exact amount without the extra step :)

Use the graph below to fill in the blank with the correct number:
f(0) = (1 point)
From the graph,
f(0) = 1
Notice that when x = 0, y = 1.
If we plot the point (0,1) It's the same point. So f(0) = 1 is basically substituting x = 0 and get y = 1

Draw three lines with slope 2, and three lines with slope 1/3. What do you notice?
Answer:
for every inch the line goes to the right, it drops by 1/3 of an inch
Step-by-step explanation:
Using two of the points on the line, you can find the slope of the line by finding the rise and the run
The slope of a line represents the rate of change of the line.
When a line has a slope, then such line is represented by a linear equation.
A linear equation is represented as:
[tex]\mathbf{y = mx + b}[/tex]
Where m represents slope, and b represents the y-intercept.
This means that, the following line equations have a slope of 2
[tex]\mathbf{y = 2x}[/tex]
[tex]\mathbf{y = 2x + 1}[/tex]
[tex]\mathbf{y = 2x - 1}[/tex]
And the following line equations have a slope of 1/3
[tex]\mathbf{y = \frac 13x}[/tex]
[tex]\mathbf{y = \frac 13x + 1}[/tex]
For the line equations with a slope of 2.
As the line runs (horizontally) by 1 point, it rises by 2 points (vertically)
For the line equations with a slope of 1/3
As the line runs (horizontally) by 1 point, it rises by 1/3 points (vertically)
See attachment for the drawing of the lines

1.Jamal sells sandwiches. He spends $2.70 per sandwich on ingredients and then adds a 110% markup. What is the selling price of one sandwich?
2.Elizabeth goes to a restaurant where her bill comes to $18.50. She leaves the server a 22% tip. What is the total cost of going to the restaurant?
Answer:
2.70 + 110% = 5.67$ per sandwich
110% out of 2.70 is 2.97, so 2.70+2.97 = 5.67
18.50 + 22% = 22.57$ total cost
22% out of 18.50 is 4.07, so 18.50+4.07 = 22.57

The table below models the cost, y, of using a high-efficiency washing machine and a standard washing machine over x number of years.
Which equation represents the cost of the high-efficiency washing machine over a given number of years?
Which equation represents the cost of the standard washing machine over a given number of years?
After how many years of use would the washing machines cost the same amount?
Which washing machine would be the more practical purchase if kept for 9 years?
Q1: y = 25x + 500
Q2: y = 30x + 400
Q3: 20 years
Q4: Standard washing machine
Step-by-step explanation:1 - First Problem"Which equation represents the cost of the high-efficiency washing machine over a given number of years?"
NOTE: There will be a lot of reading at first, however, it covers the process of the first question and the second.
1.1 - Pinpointing key terms
This is a useful skill that never stops being practiced. The trick to it in this situation is to cross-examine information which, in our case, is the word problem and the graph.
Doing this we will notice this;
"Which equation represents the cost of the high-efficiency washing machine over a given number of years?"
For further clarification, we will look specifically at these two columns in our chart to answer the first problem
1.2 - Deciding which formula would best represent the data
The slope-intercept formula is used to measure data trends, and as such we can use it, and its rules, here. (Technically f(x) in general is universally recognized for this.)
1.3 - Determine which column to assign as the x values and which to assign as y values
Our y-axis is what we're measuring for, and that we want to find, and our x-axis is for the values that which our y values change in correlation to.
We want to find the high-efficiency cost, we'll as a result assign that column as the y values, at any given year, which in this case was given
1.4 - Find the slope
To do this we'll use the slope formula
[tex]Slope = m = \frac{rise}{run} = \frac{change~in~y}{change~in~x} = \frac{y_2~-~y_1}{x_2~-~x_1}[/tex]
1.4.1 - Defining variables of slope formula
[tex]x__1[/tex] means the first x value of two consecutive points
[tex]x__2[/tex] second x value
(Must be to the right of the first point on a graph, greater than)[tex].^{*Note~1}[/tex]
NOTE: [tex]y__{2}[/tex] [tex]is~derived~from~the~y~value~that~corresponds~with~x__2[/tex]; [tex]and[/tex] [tex]y__1[/tex] [tex]from~x__1[/tex]
Further help in understanding this concept
To help you visualize I'll convert the variables to points
[tex]\left[\begin{array}{ccccc}Number~of~years&|&high-efficiency~cost&|&point\\1&|&525&|&(1, 525)\\2&|&550&|&(2, 550)\\3&|&575&|&(3,575)\end{array}\right][/tex]
1.4.2 -Putting it all together
In this case, we'll use (1, 525) and (2, 550)
As a result of defining of variables section, our x1 and y1 is (1, 525) and our x2 and y2 is (2, 550)
So, now lets plug and solve
(y2-y1)/(x2-x1)
On top:
y2 - y1 = 550-525 = 25
On the bottom
x2 - x1 = 2 - 1 = 1
Therefore our slope is 25/1 which is 25
1.5 - Finding our y-intercept, b, for y = mx + b
All we need to do now that we know the slope, and that we have a chart, is continue the trend in reverse to find y
because our slope was 25/1 that means that y increases by 25 for every increase of 1 that occurs in our x;
The reverse is for every decrease of 1 x, y decreases by 25
Using that we'll need to decrease our x and y accordingly until x equals 0
(1, 525)
- (1, 25)
(0, 500)
Our y intercept, b, in this case is 500
Therefore now we have the needed information to complete the formula
y = mx + b
y = 25x + 500
2 - Second Problem"Which equation represents the cost of the standard washing machine over a given number of years?"
2.1-2 - Assigning x and y
y = Standard Cost
x = Number of years (given)
y = mx + b
2.3 - Find the slope
[tex]Slope = m = \frac{rise}{run} = \frac{change~in~y}{change~in~x} = \frac{y_2~-~y_1}{x_2~-~x_1} = \frac{460~-~430}{2~-~1} = \frac{30}{1} = 30[/tex]
2.4 - Find the y-intercept, b, using the slope
(1, 430)
- (1, 30)
(0, 400)
y-intercept = b = 400
2.5 - Plug it in slope-intercept form
y = mx + b
y = 30x + 400
3 - Third Problem"After how many years of use would the washing machines cost the same amount?"
We need to set the two equations equal to each other, and thanks to the fact they're both equal to y, this allows us to do so through substitution
3.1 - Write the equations
y = 25x + 500
y = 30x + 400
3.2 - Substitute an equation in for the y of the other and simplify and solve algebraically
30x + 400 = 25x + 500
- 400 -400
-25x -25x .
5x = 100
x = 20
After 20 years they will be equal
4 - Fourth Problem"Which washing machine would be the more practical purchase if kept for 9 years? "
To answer this we just plug in 9 for x in each equation and see which is cheaper
4.1 - Rewrite
High Efficiency
y = 25x + 500
Standard
y = 30x + 400
4.2 - Plug in
High Efficiency
y = 25(9) + 500
Standard
y = 30(9) + 400
4.3 - Solve
High Efficiency
y = 25(9) + 500
y = 225 + 500
y = 725
Standard
y = 30(9) + 400
y = 270 + 400
y = 670
In this case the standard would cost less therefore our answer is the standard washing machine
