Write the equation for the line can somebody help me and show me how to do it
Answers
(NOTE: many questions may ask you to put the equation in a certain format. This answer is assuming you can put it in slope-intercept form.)
Answer:
y= -3x-3
Step-by-step explanation:
1) A handy way to write an equation from a graph is to use the slope-intercept form: y = mx + b. In this format, the "m" represents the slope - or the measure of the steepness of the graph (we'll get more into this in the next step). The "b" represent the y-intercept, or where the point in which the graph hits the y-axis. If you know what the slope and y-intercept is, it is very easy to create an equation!
2) So let's find the slope first. The slope of an equation is represented by [tex]\frac{rise}{run}[/tex] , or the change in the y from each point, going up or down, divided by the change of x, going from left to right. So, knowing this, we can take two points we see the line hit and count the change from the x and y values.
Let's take the points (-1,0) and (0,-3). To find the rise, or the change in y, start from (-1,0) and count how many units it would take vertically to get to (0,-3). If you went down, then be sure to add a negative to the number of units you counted. To find the run, or change in x, do the same and count how many steps it would take horizontally to get to (0,-3) too. If you went left, then be sure to add a negative to the number of units you counted. So, if you did it correctly, you would get -3 as your rise and 1 as your run. Using the [tex]\frac{rise}{run}[/tex] equation, divide -3 by 1 and your slope is -3.3) Now, let's find the y-intercept. This part is much easier: just look at the graph and find the point where the line hits the y-axis. In this case, it's (0,-3).
4) All you have to do now is plug the slope and y-intercept we found into y = mx + b. So, put the slope in the "m" place and remember to put the y-value of the y-intercept into the "b" place.
This should get you y= -3x - 3 as your answer!

A store is instructed by corporate headquarters to put a markup of 25% on all items. An item costing 8$ is displayed by the store manager at a selling price of 2$. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Answers
Answer:
the correct selling price is $10
And, the error is that the manager put the markup percentage as a selling price instead of adding up the markup to the cost price
Step-by-step explanation:
The computation is shown below:
Given that
Markup = 25%
Cost of an item = $8
Selling price of an item = $2
Based on the above information
The amount of markup would be
= 25% × 8%
= $2
Now amount after markup is
= $2 + $8
= $10
Hence, the correct selling price is $10
And, the error is that the manager put the markup percentage as a selling price instead of adding up the markup to the cost price
Answer:
part A:The correct selling price is $10
Part B:And, the error is that the manager put the markup percentage as a selling price instead of adding up the markup to the cost price

2x -14 = -9 answer for this equation
Answers
Answer:the exact form is x=5/2 if its wrong then its probably wrote in a different way
Step-by-step explanation: Move all terms that don't contain
x
to the right side and solve.
Answer:
x= 2.5
Step-by-step explanation:
Simplifying
2x + -14 = -9
Reorder the terms:
-14 + 2x = -9
Solving
-14 + 2x = -9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '14' to each side of the equation.
-14 + 14 + 2x = -9 + 14
Combine like terms: -14 + 14 = 0
0 + 2x = -9 + 14
2x = -9 + 14
Combine like terms: -9 + 14 = 5
2x = 5
Divide each side by '2'.
x = 2.5
Simplifying
x = 2.5

The answer to #7 is the mint milkshake is thicker
The answer to #8 is A is 12 and B is 18
The answer to #9 is A is 33 and B is 15
Missing values:
1. 1:7 , 3:21, 18:126
2. 20:12 , 10/3:2 , 8 1/3:5
3. 42:21 , 6:3 , 48:24
4. 4:10 , 8:20 , 16:40
5. 36:32 18:16
Step-by-step explanation:
#2: The first ratio is shown, which is 5:3. Meaning, that the bottom number (cakes) is multiplied by 5/3 in order to get the top number (pies). We can apply that to the ratio with 12 cakes, 12 multiplied by 5/3 is 20. The next ratio involved 10/3 pies. Since that is the "top" number (see chart), 10/3 need to be multiplied by 3/5 instead of 5/3. By doing that, the number of cakes is 2.
#7: The ratio of milk to ice cream in the mint milkshake is 1.25:4
The ratio of milk to ice cream in the strawberry milkshake is 1.75:5
When the ratios are divided, the quotient for the mint milkshake (0.3125) is LESS than the quotient for the strawberry milkshake (0.35). This means that there is less milk and more ice cream (ratio-wise) in the mint one.

Answers
Answer:
The two number are :
x = 1411
y = 1079
Step-by-step explanation:
Let the two numbers = x and y
The sum of two numbers is 2490
x + y = 2490..... Equation 1
If 6.5 percent of one no. is equal to 8.5 percent of the other,
Hence:
6.5% of x = 8.5% of y
0.065x = 0.085y
Make x the subject of the Formula
x = 0.085y/0.065
x = 1.308y
We substitute 1.308y for x Equation 1
x + y = 2490..... Equation 1
1.308y + y = 2490
2.308y = 2490
y = 2490/2.308
y = 1078.8561525
y = 1079
x + y = 2490..... Equation 1
x = 2490 - y
x = 2490 - 1079
x = 1411

Shawn is a member of a book club. He pays a $50 yearly membership fee and can purchase books through the club for $5 each. His total annual cost is a function of the number of books, b, that he purchases in a year:
C(b) = 5b + 50
What is the total cost if he purchase 17 books in a year?
Answers
Answer:
The annual total cost is $135 when he purchases 17 books
Step-by-step explanation:
Given function is:
C(b) = 5b + 50
Here c is the output which is cost and b is the input which is number of books purchased in an year.
In order to find the total cost when he purchases 17 books, we have to put 17 in place of b and find the cost.
So,
Putting b = 17
[tex]C(17) = 5(17) + 50\\= 85+50 = 135[/tex]
Hence,
The annual total cost is $135 when he purchases 17 books
