Answer:4+x/3=2
Step-by-step explanation:
4 more=4+
the quotient of a number and 3= x/3
the anwser = =2
So if ur tryin to figure out the unit rate than u do 12/5 and the answer is 2.4
Which relation is a function? A. {(8,3), (-1,-1), (8,7), (-1,7)} B. {(1,6), (2,-3), (2,7), (3,7)} C. {(-3,6), (-3,9), (-1,4), (0

A. Not a function since x = 8 repeats. We have x = 8 pair up with y = 3 and y = 7 at the same time.
B. Not a function for similar reasons. Now x = 2 repeats. We have x = 2 pair up with y = -3 and y = 7
C. Not a function. We have x = -3 pair up with both y = 6 and y = 9 at the same time.
D. This is a function. Each x value is listed once and only once. Any input (x) leads to exactly one output (y). For choices A through C, it is possible to draw a vertical line through more than one point, thereby failing the vertical line test. In choice D, it is not possible to draw a vertical line through more than one point of this list. So this relation passes the vertical line test.
Answer: Choice D
Answer:
in short the answer is 5
Step-by-step explanation:
perimeter= 2(L+W)
2(L+W)=28
2(2W-1+W)=28
2(3W-1)=28
6W-2=28
6w=30
W=5
Move the 5 to the other side:
Divide both sides by 2:
Recall the definition:
Invert both sides
This is true when
If you need both angles to be in [0,2pi], you can recall
So, the solutions are
