thats cool but is this a math problem? there is no question to answer here just fyi
Step-by-step explanation:
Answer:
It is important because it allows you to calculate the surface area of a trapezoidal prism
Step-by-step explanation:
Answer: (0,-15)
--------------------------------------------------
Explanation:
Add up the x coordinates to get 1+(-1) = 0. Divide this sum in half to get 0/2 = 0. Therefore the x coordinate of the midpoint is 0.
Repeat for the y coordinates. First add the y coordinates to get -7+(-23) = -30. Then divide that result in half to get -30/2 = -15. So the y coordinate of the midpoint is -15.
Overall, the midpoint is (0,-15).
Answer:
$78
Step-by-step explanation:
In the equation y = 2x + 40, x represents the number of months the member is a part of the club.
We are given that a certain member is part of the club for 19 months, so we substitute the number 19 in for x:
y = 2x + 40 = 2 * 19 + 40 = 38 + 40 = 78.
Thus, the total cost is $78.
Hope this helps!
