Answer:
The first one is a function. The other two are not functions.
Step-by-step explanation:
To find this, you use the vertical line test. If the vertical line touches multiple points on the graphed line, it is not a function. If the vertical line only touches the graphed line at one point, it is a function.
Good Luck! I hope this helps!

Answer:
11/45 is the correct answer
Step-by-step explanation:
2/3 x 2/3 = 4/9
1/3 x 3/5 = 3/15
convert 4/9 - 3/15 common denominators
20/45 - 9/45 = 11/45

Answer: D) 32
Step-by-step explanation:
The area of a parallelogram equals its base times its height. Substitute the base and area into this formula to solve for the height:
A=bh
40=(5)(h)
h=8
If ABCD is a parallelogram, opposite sides are parallel, so AB is parallel to DC. If AB is parallel to DC, EB is parallel to DC. Since EB is parallel to DC, quadrilateral EBCD has at least one pair of parallel sides, making it a trapezoid. The area of a trapezoid is equal to
where h is the height,
is one base, and
is the other base. Plug the necessary values into the formula:
A=


h=8
A=
A=32
The answer is D) 32.
