Yes it is. In order for something to be a function, no X values can be the same, which is the case here.
Answer:
27.72
Step-by-step explanation:
Sorry about before i made a slight mistake
Okay if there are 8 teachers and 6 reams of paper you would have to divide 6 by 8 and you would get 0.75
6/8= 0.75
each teacher would get 0.75 (3/4) of a ream of paper
Direct variation is when one variable changes the other changes in proportion of the first, therefore all the above
This relationship again shows that since w and y are perpendicular to each other that the smaller angles will add up to give 90 degrees.
3x + 3 + 15 = 90
3x + 18 = 90
3x = 90 - 18
3x = 72
X =72/3
X = 36 degrees
