Which graph represents the linear function y = x 3/4– 4?
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
[tex]y=\frac{3}{4}x-4[/tex]
This is a linear equation (the graph is a line)
To identify the graph find out the intercepts
Find out the y-intercept
The y-intercept is the value of y when the value of x is equal to zero
For x=0
[tex]y=\frac{3}{4}(0)-4=-4[/tex]
The y-intercept is the point (0,-4)
Find out the x-intercept
The x-intercept is the value of x when the value of y is equal to zero
For y=0
[tex]0=\frac{3}{4}x-4[/tex]
[tex]\frac{3}{4}x=4[/tex]
[tex]x=16/3=5.33[/tex]
The x-intercept is the point (5.33,0)
therefore
The graph in the attached figure
The graph of the linear function y = x 3/4–4 can be generated by understanding that '3/4' is the slope and '-4' is the y-intercept. This implies for every horizontal increase of 4 units, there's a vertical rise of 3 units. The function intersects the y-axis at -4.
Explanation:The linear function in question, y = x 3/4–4, can be graphed by understanding how the terms within the equation shape the line. The term '3/4' in the equation is the slope of the line and '–4' is the y-intercept. The slope or the rate of change is less than 1 which means for every increasing step in 'x', 'y' increases by less of a step (3/4 of a step, in this case). The linear function intersects the y-axis at -4. Therefore, when you plot x and y values, keep in mind that for every rise of 3 on the vertical axis, there's an increase of 4 on the horizontal axis. Start by marking the y-intercept (0, -4) and use the slope (3/4) to find the next points. From the y-intercept, move 3 units up and 4 units to the right. Repeat this pattern to generate other points that lie on the line.

have a nice day!!
A cell phone plan costs $23.70 per month for 700 minutes of talk time. It costs an additional $0.06 per minute for each minute over 700 minutes. To get e-mail access it costs 20% of the price for 700 minutes of talk time. Your bill wich includes e-mail is the same each month for 6 months. The total cost for all 6 months is $195.12. Write and solve an equation to find the minutes of talk time you use each month.
Your equation is...
195.12=6(0.06m+23.70+0.20(23.70))
You use_____ minutes talk time each month
Final answer:
The equation can then be solved to find the value of 'm', representing the minutes of talk time. In this case, the answer is 68 minutes of talk time each month.
Explanation:
To find the minutes of talk time you use each month, we can set up an equation based on the given information. Let's assume that the number of minutes of talk time you use each month is represented by 'm'.
The total cost for all 6 months is $195.12, which is equal to the sum of the monthly costs. Each month, the cost of the cell phone plan is $23.70 for 700 minutes of talk time, plus an additional $0.06 per minute for each minute over 700 minutes. Additionally, to get email access, it costs 20% of the price for 700 minutes of talk time.
Based on this information, the equation is: 195.12 = 6(0.06m + 23.70 + 0.20(23.70))
To solve the equation, we can simplify it: 195.12 = 6(0.06m + 23.70 + 4.74)
195.12 = 6(0.06m + 28.44)
Divide both sides of the equation by 6, we get: 32.52 = 0.06m + 28.44
Subtract 28.44 from both sides of the equation, we get: 32.52 - 28.44 = 0.06m
4.08 = 0.06m
Divide both sides of the equation by 0.06, we get: m = 68
Therefore, you use 68 minutes of talk time each month.
Final answer:
After setting up the equation based on the total cost for 6 months, we calculate that the user talks for a total of 768 minutes each month. This includes the 700 minutes in the plan and an additional 68 minutes of talk time.
Explanation:
To solve for the number of minutes of talk time used each month, we first set up an equation based on the information given. The total cost for 6 months is $195.12 which includes the monthly plan cost, the additional cost per minute after 700 minutes, and the email cost which is 20% of the 700 minutes talk time plan.
The equation, therefore, is 195.12 = 6(0.06m + 23.70 + 0.20(23.70)), where m is the number of minutes used over 700. Let's solve the equation step-by-step:
Start with the original equation: 195.12 = 6(0.06m + 23.70 + 0.20 × 23.70).Calculate 20% of 23.70 which is 0.20 × 23.70 = 4.74.Add the monthly plan cost and the e-mail access cost: 23.70 + 4.74 = 28.44.Substitute the sum into the equation: 195.12 = 6(0.06m + 28.44).Distribute the 6: 195.12 = 0.36m + 170.64.Subtract 170.64 from both sides: 195.12 - 170.64 = 0.36m, which simplifies to 24.48 = 0.36m.Divide by 0.36 to find m: m = 24.48 / 0.36 = 68.Therefore, you use 68 minutes over the 700 included minutes, which means you use a total of 700 + 68 = 768 minutes of talk time each month.

A. Rules everyone follows
B. A set process people follow
C. A general rule most people follow
D. A way to measure growth
Answer: C. A general rule most people follow
Step-by-step explanation: A rule of thumb is a principle with broad application that is not intended to be strictly accurate or reliable for every situation.
The term 'rule of thumb' refers to a general rule or principle that people often follow, based on practical experience and wisdom. It isn't universally true for all situations but serves as a useful guideline.
Explanation:A rule of thumb generally refers to an option C, which is a general rule that people tend to follow, but it isn't necessarily universally true or applicable to every situation. It's a guideline or heuristic that helps simplify or solve problems, based on practical experience rather than theory.
For example, a common rule of thumb in cooking may be that 'one cup of uncooked rice serves two people'. However, this may vary depending on the individuals' appetites, age, and more.
So, from options given, a rule of thumb most closely aligns with 'C: A general rule most people follow'.

A circle has a radius of 4 inches and a central angle of 45°. what is the measure of the arc length associated with this angle?
Answer:
[tex]arc\ lenght=\pi[/tex]≈[tex]3.14[/tex]
Step-by-step explanation:
You need to use the formula for calculate the arc lenght:
[tex]arc\ length=2\pi r(\frac{C}{360})[/tex]
Where "C" is the central angle of the arc in degrees and "r" is the radius.
You know that the measure of the radius of the circle is 4 inches and the central angle is 45 degrees, then you can substitute into the formula [tex]arc\ length=2\pi r(\frac{C}{360})[/tex].
Therefore, you get that the measure of the arc length is:
[tex]arc\ length=2\pi r(\frac{C}{360})\\\\arc\ length=2\pi (4in)(\frac{45\°}{360})[/tex]

A sphere has a height of 26. Find the surface area, volume and density (D=m/v , where m is 72)
Answer:
Surface Area: 2123.72
Volume: 9202.77
Density: 0.0078
Step-by-step explanation:
For a sphere, the height is the diameter.
Also we know the radius is half of the diameter.
Since height is 26, diameter is 26 as well. Thus, radius is half of 26, which is 13.
Formulas:
Surface area of sphere = 4πr^2
Volume of sphere = [tex]\frac{4}{3}\pi r^3[/tex]
Density = mass/volume
Firstly, the surface area:
[tex]4\pi r^2\\=4\pi (13)^2\\=2123.72[/tex]
Next, the volume:
[tex]\frac{4}{3}\pi r^3\\=\frac{4}{3}\pi (13)^3\\\\=9202.77[/tex]
Lastly, density:
[tex]\frac{Mass}{Volume}\\=\frac{72}{9202.77}\\=0.0078[/tex]

what is the total bill if a large pizza is $16.25, tax is 3% and you tip the waiter 20%
Answer:
You want to leave a 15% tip on a meal that cost $16.25.
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $16.25 meal cost is.This is always done by multiplying 0.15 by $16.25, or
0.15 x $16.25=$2.44.
So, the amount of tip you are going to leave is $2.44.
This makes the total cost of your meal (to write on your charge slip or other payment)
$16.25 + $2.44 = $18.69.
Answer:
$19.99
Step-by-step explanation:
16.25 + 3% tax + 20% tip
16.25 * 0.03 = .49
16.25 * .20 = 3.25
16.25 + .49 + 3.25 = $19.99

I need the answer to question 8. 50 points up for grabs
Let iron = x
There is 1.5 times the amount of zinc that there is iron, so you get zinc = 1.5x
There is 3 times as much copper as there is zinc, so 1.5 x 3 = 4.5, so copper equals 4.5x
Now all three need to equal the total weight of 210:
X + 1.5x + 4.5x = 210
Simplify:
7x = 210
Divide both sides by 7:
x = 210 /7
x = 30
Now you have a value for x, you can solve for the amount of each material.
Iron = x = 30 g
Zinc = 1.5x = 1.5(30) = 45 g
Copper = 4.5x = 4.5(30) = 135g
There is 45 g of zinc.
Let iron =x
There is 1.5 times the amount of zinc then there is iron, so zinc = 1.5x
There is 3 times as much copper then there is zinc, so 1.5*3=4.5, so copper equals 4.5x
