A bakery sells 3642 pastries in 2010. The bakery sells 8422 pastries in 2015. Write a linear model that represents the number y​ of pastries that the bakery sells x​ years after 2010

Answers

Answer:

y = 936x + 3742

Step-by-step explanation:

If it is a linear model, then we should have a slope and y-intercept with the equation representing the model as;

y = mx + c

where m is the slope and c is the y-intercept

Thus, we have for the slope;

(8422-3742)/(2015-21010) = 4680/5 = 936

So the equation will be;

y = 936x + c

To get c , we can use the years after 2010 which is 2015 in this case

8422 = 936(5) + c

c = 8422- 4680

c = 3742

So the linear model is;

y = 936x + 3742

Point A located at -11 and -7 on the coordinate plan is reflected over the X axis to form point B.Then point B is reflected over the y axis to form point C. What are
the coordinates of points B and C

Answers

Answer:

The coordinates of B are (-11,7)

The coordinates of C are (11,7)

Step-by-step explanation:

Reflection of Points

Given a point (x,y), it can be reflected in several ways. Two of the most-used are reflection over the x-axis and reflection over the y-axis.

When the point is reflected over the x-axis, the x-coordinate is unchanged, and the y-coordinate is inverted: (x,y) -> (x,-y).

When the point is reflected over the y-axis, the y-coordinate is unchanged, and the x-coordinate is inverted: (x,y) -> (-x,y).

Point A is located at (-11,-7). It's reflected over the x-axis to form point B whose coordinates are (-11,7).

Then, point B is reflected over the y-axis to form point C with coordinates (11,7).

The coordinates of B are (-11,7)

The coordinates of C are (11,7)

The table shows the number of items of each brand that were returned over the past year and the total sold. which brand should the store eliminate? A. Brand A B. Brand B C. Brand C D. Brand D

Answers

The brand that the store should eliminate out of the 4 given brands using the data in the table is; Brand C

How to Solve Percentage Problems?

To find the brand that the store should eliminate we need to find the percentage of sold items that were returned and pick the highest percentage as the brand the store should eliminate.

Brand A percentage = 33/636 * 100% = 5.19%

Brand B percentage = 15/492 = 3.05%

Brand C percentage = 29/362 * 100% = 8.01 %

Brand D percentage = 32/767 * 100% = 4.17%

Brand C has the highest percentage and as such it is the brand that should be eliminated.

Answers

Answer:13.7

Step-by-step explanation:

The question is asking us to build an algebraic model of this question, to do this, we need to use the slope intercept form.

Let's first identify the known data. We know that a pizza with two toppings is 9.95. In addition, we know that a topping itself is 1.25. We need to find the y intercept first in order to solve this equation, therefore we need to find how much a pizza his without the two toppings. So, we do 1.25(2)=2.5 and subtract it from 9.95. 9.95-2.5= 7.45. Now, this is our y intercept, because this will always stay the same and this is where we always start off. The slope itself however will be 1.25x, because x is the amount of toppings. So, as of now, we have constructed our equation

y=1.25x+7.45

We are looking to see how much a pizza is with 5 toppings, so we plug 5 into x

y=1.25(5)+7.45= 13.7
