Let x = number of problems on test
If he got 14 wrong, then x - 14 is the number correct.
x - 14 = .72x
.28x - 14 = 0
.28x = 14
x = 50
The test consisted of 50 problems.
Answer:
C
Step-by-step explanation:
Any time you move up or down, it affects the "y" coordinate, and going up is positive so 5 units up is 
.
Moving left or right affects the "x" coordinate and moving left is negative so
Hence, C is the correct answer
12 red marked to 12 blue markers is 144
A. If p = a number is negative and q = the additive inverse is positive, the original statement is p → q.
B. If p = a number is negative and q = the additive inverse is positive, the inverse of the original statement is ~p → ~q.
D. If q = a number is negative and p = the additive inverse is positive, the contrapositive of the original statement is ~p → ~q.
The x-coordinate of the midpoint will be the average of the two given x-coordinates, and the y-coordinate will be the average of the two given y-coordinates.
This can be written as
midpoint =
,
where the given points are (x1, y1) and x2, y2).
In the problem, you have (4, -2) and (-8, 6).
The midpoint will be
