Sasha made cups of lenonade to sell at her stand. She sold 9 cups of lemonde in the first hour. For each hour after that, she sold five cups. She was putsode for a total of 4 hours. How many cups of lemonade did she sell?

24 cups

Step-by-step explanation:

Sasha worked a total of 4 hours.

In the first hour, Sasha sold a total of 9 cups of lemonade.

There are 3 hours left, and for each of these hours, she sold 5 cups of lemonade.

So, if we sum all the cups of lemonade she sold in each hour, we have:

Total cups sold = 9 + 5 + 5 + 5 = 24

She sold a total of 24 cups of lemonade.

She sold 24 cups in total

Step-by-step explanation: The total number of cups sold initially was 9 in the first hour. Then after that she sold 5 every hour. We can derive an expression for this as follows

9 + 5h as the total number of cups sold at the end of h hours. Since she sold some for the first hour and then another three hours (total was four hours), we shall now substitute for h equals 3 into the expression already derived.

Total cups sold x, can be calculated as;

x = 9 + 5h

x = 9 + 5(3)

x = 9 + 15

x = 24

Therefore, she sold 24 cups of lemonade.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
