Write the equation of the line from the table below.
to get the equation of any straight line, we simply need two points off of it, let's use those two in the picture below.
[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{9000})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{3000}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{3000}-\stackrel{y1}{9000}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{2}}} \implies \cfrac{ -6000 }{ 2 } \implies - 3000[/tex]
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{9000}=\stackrel{m}{- 3000}(x-\stackrel{x_1}{2}) \\\\\\ y-9000=-3000x+6000\implies {\Large \begin{array}{llll} y=-3000x+15000 \end{array}}[/tex]

13. A grocery store sells 12 bottles of water for $8 and 36 bottles of water for $20.
Is the cost of the water proportional to the number sold? Explain.
a) Proportional because the unit rates are $1.50 per bottle.
b) Proportional because the unit rates are $1.80 per bottle.
c) Nonproportional because the bottles have different unit rates.
d) Nonproportional because one grocery store has more bottles.
What’s the answer to 10-
11-12-13
-26 Is the answer.
____________________
First you have to do: 10 - 11 = -1
Then its -1 - 12 or -1 + -12 (same thing) = -13
After that, do -13 + -13 = -26.

The graph shows the cost of producing gadgets. which equation best represents the cost C of producing n gadgets?
Answer:
[tex]C = 0.10n[/tex]
Step-by-step explanation:
If you study the graph you will see that there is no cost for producing zero gadgets. Cost = $0
For 100 gadgets the cost is $10
For 200 gadgets the cost is $20
etc
So the cost in $ is 1/10 times the number of gadgets
For 1 gadget, it costs [tex]\$\dfrac{1}{10}[/tex] or $0.10
For n gadgets it should cost $[tex]0.1n[/tex] same as [tex]\$\dfrac{n}{10}[/tex]
Mathematically speaking the graph represents the equation of a straight line which is of the form
y = mx + b
where y represents the vertical axis and x the horizontal axis
The variable m represents the slope of the line which is the increase of y for every unit increase in x.
The slope, m can be determined by using the formula [tex]\displaystyle \dfrac{y2-y1}{x2-x1}[/tex] where x1, y1 and x2, y2 are two points on the graph
This is also called rise/run
b is called the y-intercept and it represents the value of y where the line crosses the vertical axis
The difference here is that instead of y, we are using C as the variable for the vertical(y) axis and n as the variable for the horizontal(x) axis
So we get the modified equation as
C = m·n + b
We can see that when n = 0, C = 0 so b = 0 because the vertical intercept is zero
To calculate m, take any two points on the line
I choose (0, 0) and (100,10)
[tex]\rm Slope \;m = \dfrac{10-0}{100-0} = \dfrac{10}{100} = \dfrac{1}{10} = 0.10\\\\[/tex]
This means that for every gadget produced the cost will increase by $0.10
The equation becomes C = 0.10n + b and since b is 0 we get
[tex]C = 0.10n[/tex]

Answer:
y = 7x +10
Step-by-step explanation:
Given a y-intercept of 10 and a slope of 7, you want the equation of the line in slope-intercept form.
Slope-intercept equationThe slope-intercept form equation of a line is ...
y = mx +b . . . . . . . where m is the slope, and b is the y-intercept
You are given a slope of 7 (m=7) and a y-intercept of 10 (b=10), so the equation is ...
y = 7x +10

Under standard atmospheric conditions, water will not remain a liquid if its temperature is less than or equal to 0°C or if it is greater than or equal to 100°C. Suppose you have a cup of water that is room temperature, or 20°C.
a. Write a compound inequality to represent the number of degrees of Celsius c that the temperature of the cup must change to longer be liquid.
Answer: +80°C or -20°C
Step-by-step explanation:
This is the answer because if you add 80 then it will equal 100°C and freeze and if 20°C is taken away it will equal 0°C and freeze.

Which of the following is not a step when drawing an angle?
A. Draw a ray
B. Connect the arrows with a straight line
C. Line up the baseline on the protractor with the ray
D. Draw arrows on both ends to make them rays
Answer:
B
Step-by-step explanation:
a angle is not the same thing as a triangle and so therefore the lines at the end do not need to be connected.
What is the asymptote of the graph of an exponential growth or exponential decay function? Explain your reasoning.
Let's consider an exponential decay function.
As an example, let's look at [tex]f(\text{x}) = 100(0.5)^{\text{x}}[/tex]
Here is a table of selected values:
[tex]\begin{array}{|c|c|} \cline{1-2}\text{x} & \text{f(x)}\\\cline{1-2}0 & 100\\\cline{1-2}1 & 50\\\cline{1-2}2 & 25\\\cline{1-2}3 & 12.5\\\cline{1-2}4 & 6.25\\\cline{1-2}5 & 3.125\\\cline{1-2}6 & 1.5625\\\cline{1-2}\end{array}[/tex]
As x gets bigger, y = f(x) is slowly approaching y = 0. It will never get to this exact value because we keep taking half of the previous y value (eg: we go from y = 25 to y = 12.5); there's no way to arrive at zero through this continuous halving process. If x/2 = 0, then x itself must be 0. But we started off with a nonzero value.
Visually, the curve is slowly approaching the x-axis. We say that the horizontal asymptote is y = 0 which is directly overlapping the x-axis. Think of the asymptote as an electric fence you can get closer to but not actually touch.
See the graph below. I used Desmos to create the graph.

Answer:
The given point is not on the line.
Step-by-step explanation:
3 represents x
3 represents y
1. Plug in the numbers to x and y variables
y= [tex]-\frac{2}{3}[/tex] x + 1
3= [tex]-\frac{2}{3}[/tex] (3) + 1
2. Cancel out the greatest common factor
3=-2+1
3. Solve
3=-1
If the numbers do not equal each other, then the equality is false.
Step-by-step explanation: 1. Plug in the numbers to x and y variablesy= x + 13= (3) + 1
2. Cancel out the greatest common factor 3=-2+13. Solve3=-1
What is this function's rate of change? y = 2x + 1
Step-by-step explanation:
the rate of change or slope is the factor of x, when we have the function in the form y = ...
so, it is 2.
that means y changes by 2 whenever x changes by 1.

Slope-intercept form is: y = mx + b
where m is the slope and b is the y-intercept.
Since you're told the slope is 1/8 and the y-intercept is -7, you just plug those into the form:
y = 1/8 x - 7
Note that the "–" in front of the 7 is already part of the answer on paper, so you don't need to add a second one.
Can someone help, please
Answer:
y = 2x + 4/5
Step-by-step explanation:
Slope-intercept form is written as:
y = mx + b, where (x,y) is a point on the line, m is the slope, and b is the y-intercept.
To get 10x - 5y = -4 into the form y = mx + b, you'll first want to get y by itself. You can start by subtracting 10x from both sides.
10x - 5y = -4
-5y = -10x - 4
As you can see, y still has a coefficient of -5 in front of it, so we'll have to divide the entire equation by -5 (you have to divide each term individually).
-5y = -10x - 4
y = 2x + 4/5
Can someone help, please

The purchase price of a camcorder is $588. What is the total price if the sales tax rate is 4.5%?
Hello,
The sales tax for a camcorder that costs $588 would be $588 * 0.045 = $26.46. Therefore, the total price would be $588 + $26.46 = $614.46.
The answer is: $614.46

Mrs maggio needs 48 hot dogs harris teeter sells a 6 pack of hot dogs for 5.10$ and 8 pack for 6.88$ sould mrs maggio buy 8 six packs or 6,8 packs
Answer:
Eight 6-packs
Step-by-step explanation:
6-pack of hot dogs for 5.10$
8-pack of hot dogs for 6.88$
To figure out the answer, we compare the prices:
The price of six 8-packs is $41.28 ($6.88 x 6)
The price of eight 6-packs is $40.80 ($5.10 x 8)
As we can see, the cheaper option would be to buy eight 6-packs, which is our answer.
