Answer:

x = 80

Step-by-step explanation:

cuz 1 side is 50, the other side has gotta be 50 too. 50 + 50 = 100, if the sum of all angles in a triangle is 180, then 180-100=80. Therefore, the remaining degrees is 80 and that's x.

PLEASE HELP!! Consider the function shown on the graph.

Complete the statements to make them true.

This is the graph of a____ function.
The x-intercept of the function is at____

Answers

Answer:

This is the graph of a linear function.

The x-intercept of the function is at (8,0)

Step-by-step explanation:

Given

The attachment

Required

Fill in the gaps

Function Type

From the attachment, it can be observed that the graph represents a linear function. See proof below

Take any 3 points of x and y

[tex](x_1,y_1) = (8,0)[/tex]

[tex](x_2,y_2) = (0,-2)[/tex]

[tex](x_3,y_3) = (4,-1)[/tex]

Calculate the slope:

[tex]m = \frac{y_3 - y_2}{x_3 - x_2}= \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{-1 - (-2)}{4 - 0}= \frac{-2 - 0}{0 - 8}[/tex]

[tex]m = \frac{-1 +2}{4}= \frac{-2}{- 8}[/tex]

[tex]m = \frac{1}{4}= \frac{2}{8}[/tex]

[tex]m = \frac{1}{4}= \frac{1}{4}[/tex]

Notice that the slope is consistent for the three coordinate points.

Hence, the graph is a linear function

x intercept

This is the point where [tex]y = 0[/tex]

From the graph;

[tex]x = 8[/tex] when [tex]y = 0[/tex]

Hence, the x intercept is 8

The selling price of an item is ​$360. After 6 months of not​ selling, it is marked down by 10​%. After another 6 months of not​ selling, it is further marked down by 20​%. Find the sale price after both markdowns.

Answers

Answer:

1st markdown = ​$324

2nd markdown = ​$259.20

Step-by-step explanation:

current price = 360

1st 6 months = 10% down

                     = 90% of 360

                     = 324

2nd 6 month = 20% down of first 6 month

                      =  20% down of 324

                      =  80% of 324

                      = 259.20

Answer:

-6 = m (i'll show my work below)

Step-by-step explanation:

-6(m-7) + 7 = -8m + 37

-6m + 42 + 7 = -8m + 37

-6m + 49 = -8m +37

     -37     =      -37

-6m + 12  =  -8m

+6m       =    +6m

12 = -2m

/-2 = /-2

-6 = m

There are two possible offers that could be applied to orange juice that would each explain this reduction in the total bill. 4: What are these two offers? 5: What are the other two offers that could explain the reduction in the total bill?

Answers

Incomplete question. The full question read;

My local store sometimes runs offers on some of its products. There are three different types of  offers that could be in place:

Buy a certain number of a particular product and get an extra one for half price.A percentage discount (always a multiple of 5%) on one particular product.A percentage discount (always a multiple of 5%) on purchases worth a total of more than $10.

The store only ever has one of these offers in place at any time.

Last week I bought

3 cartons of orange juice for $4 each1 loaf of bread for $35 packets of snacks for $1 each

This week I bought the same set of items, but only paid $18 even though the individual items still had the same price.

(4) There are two possible offers that could be applied to orange juice that would each explain this reduction in the total bill.

What are these two offers?

(5) What are the other two offers that could explain the reduction in the total bill?

Answer:

1. Buy a certain number of a particular product and get an extra one for half price

Step-by-step explanation:

By buying 2 and getting one at half the price matches the offer:

Buy a certain number of a particular product and get an extra one for half price.

This means two (2) cartons of orange juice cost $8 (4*2) + $2 cost the extra one at half price.

If he gets 58 questions correct and 22 questions incorrect, does Nevan win? How many points does he score?

Answers

Answer:

He scores 7464 points

Step-by-step explanation:

58x134= 7772

22x(-14)= -308

7772-308= 7464

Hope this helps :D

Answer:

Nevan scores 7464 points total.

Step-by-step explanation:

You multiply 58 x 134 to find out how many points he got for the correct answers. He got 7772 points.

You multiply -14 x 22 to find out how many points he lost for the incorrect answers. He lost -308 points.

Subtract 7772-308 to find the total amount of points Nevan has now. He has 7464 points.

Note:

To find out if he won or not I would need a specific number to compare his points with. This is why my answer doesn't say whether he won or not.
