Answer: the average rate of change  is 4.

Step-by-step explanation:

The average rate of change is the slope. Therefore, you must use the following formula for calculate the slope:

m=\frac{y_2-y_1}{x_2-x_1}

As you can see in the table, when x=5, y=-2 and when x=9, y=14. Then the points you must substitute into the formula are:

(5,-2) and (9,14)

Then, you obtain:

m=\frac{14-(-2)}{9-5}=4

if a store uses a selling price based markup of 40% and an item cost the store $300 what selling price would the store set for t
kirza4 [7]

Answer:

The selling price would be $420.

Step-by-step explanation:

In order to find the mark up, we need to multiply the amount it originally costs by the percentage it is being marked up.

$300 * 40% = $120

Now that we have the mark up amount, we add it to the original cost to get the sale price.

$300 + $120 = $420

3x+y=8<br>5x+y=10<br>please help me Brainly sir ​
Svet_ta [14]

Answer:

X = 1

Y = 5

Step-by-step explanation:

we have to figure out what x and y = that make both answers correct

3 x 1 = 3

3 + 5 = 8

That means that the first equation is right with X = 1 and Y = 5

Let's see the second equation

5 x 1 = 5

5 + 5 = 10

That means both equations are right so the answer would be

X = 1 and

Y = 5

taurus [48]

Answer:

517.5 mi^2

Step-by-step explanation:

Divide shapes into 3 shapes ( 1 triangle and 2 rectangles

b = 17

h = 25

Area of triangle =  Bh

A =  (17)(25)

A = 212.5 mi^2

Area of 1st rectangle = lw = 17(9) = 153 mi^2

Area of 2nd rectangle = lw = 19(8) = 152 mi^2

Area of figure = 212.5 +153 + 152 = 517.5 mi^2
