The graph shows equivalent Leah plots a point to show a fourth equivalent ratio. If the y-value of Leah’s point is 36, what is t
denis23 [38]
All you have to do is find the slope of the graph.

1) Pick 2 points: (8,9) and (16,18) for example
2) Use the slope formula (y2-y1)/(x2-x1)
3) Once you know the slope, you know how much the graph will rise for each x-unit. Find the x distance between 24 and the new point (36), and use can calculate how high the y value should be

Does that help?

if a product is it in late you receive 8/9 of you earn points you receive 72 points on your Late project how many points did you
igor_vitrenko [27]
Hello! So if your project is turned in late, you get 8/9 of the points you would've received. In this case, you only received 72 points. To find out how many points you lost, first, let's find the score you could've gotten if it was turned in on time. Let's set up a proportion like this: 72/x = 8/9. Cross multiply the values to get 648 = 8x. Divide by 8 to isolate the "x" and you get x = 81. You could've originally gotten an 81. However, you only got a 72. To find out the amount of points you lost, subtract 72 from 81. 81 - 72 = 9. You lost 9 points from your original grade.

notsponge [240]

It should be noted that the expression that.can be used to describe the sequence below is an = 2 + (n - 1)

<h3>How to illustrate the information?</h3>

It should be noted that an arithmetic sequence implies that the difference between the pair are the same.

It should be noted that the common difference between the numbers is illustrated as:

= 3 - 2 = 1.

Therefore, it should be noted that the expression that can be used to describe the sequence below is an = 2 + (n - 1)

Sales tax on a shirt is 0.07 times the cost of the shirt. The sales tax for a shirt is $1.26. Which equation could you use to fi
serious [3.7K]

Answer: First option.

Step-by-step explanation:

According to the explained in the exercise, "c" represents the cost of the shirt before sales tax.

You know that the tax on the shirt is 0.07 times its cost. This indicates a multiplication.

Then, that the sales tax is the product of 0.07 and "c":

0.07c=sales\ tax

Knowing that the sales tax for a shirt is $1.26, you can substitute this value into 0.07c=sales\ tax in order to find the equation that could be used to find the cost of the shirt before sales tax.

Then, this is:

0.07c=1.26
