Answer:
The answer is A, or the top left function.
Step-by-step explanation:
Use the vertical line test. If you can draw a straight, vertical line through the graph, and the function intersects it at 2 or more points, it is NOT a function. Using this logic, only A is the answer.

Answer:
Step-by-step explanation:
<u>The difference of −2d and −3d is equal to the difference of 1/6 and 1/3</u>
- -2d - (-3d) = 1/6 - 1/3
- -2d + 3d = 1/6 - 2/6
- d = -1/6
Answer:
P = 108cm
A = 486 cm^2
Step-by-step explanation:
To find the perimeter add up all the side
P = 36+27+ 45 =108 cm
The area is
A = 1/2 bh
A = 1/2( 27)*36
A = 486 cm^2
Explanation:
Consider the case a = -1. Then the expression becomes ...
(-1+1)(-1+1) > (-1-1)(-1-1) . . . . test case
0·0 > (-2)(-2) . . . . . simplified a bit
0 > 4 . . . . . . . . NOT TRUE
_____
If we subtract the right side from both sides, the inequality becomes ...
(a+1)(a+1) -(a-1)(a-1) > 0
a² +2a +1 -(a² -2a +1) > 0
4a > 0
a > 0
The inequality is only true for positive values of "a". For a ≤ 0, the inequality will not be true.
