A) True. The domain of both is: x ≥ 0
B) True. 1/2 is on the outside so it is vertical. 1/2 is between 0 and 1 so it shrinks.
C) False. the coefficient is not 2 (it is 1/2)
D) False. 1/2 is not on the inside with "x" so it is not horizontal.
Answer: A, B
The zero normally gives it away for example: 10,20,30,40,50
D. is the answer since (-8)(-24)=192 and so does (-16)(-12)
I assume that there is no y component to this question. Since the y value is nonexistent, the rate of change is zero.
A:0
Answer:
Since all three of the interior angles are the same degree, the three sides must be the same length. So, 3x - 5, 4x - 30, and 2x + 20 must be equal.
To solve for x, you can just set one of the sides equal to another one of the sides. I will do 3x - 5 and 4x - 30.
3x - 5=4x - 30
Add 5 to both sides.
3x = 4x - 25
Subtract 4x from both sides.
-x = -25
Divide both sides by -1.
x=25
