I guess you want to find the 4 numbers
x + x + 2 + x + 4 + x + 6 = -28
4x + 12 = - 28
4x = - 40
x = -10
so the numbers are -10, -8, -6 ,-4.
To solve you first need to pick out the most important information,
~Spent 20 minutes
~Each prob takes 2 minutes
Lets have y be the total time spent, and x the number of probs
(y/2) = x
Hope this helped!! ^-^
Answer:
Neither
Step-by-step explanation:
Parallel must have the same slope.
Perpendicular must have reciprocal slopes.
These two contain neither.
Step-by-step explanation:
Yes, because 1/4 plus 1/4 equals 2/4 (or 1/2) and 3/4-2/4 equals 1/4.
