Answer:
C
Step-by-step explanation:
The vertex form for a parabola is a(x-h)^2 + k, where h is the x coordinate of the vertex and k is the y coordinate. a represents the amount that the graph has been "squeezed". Therefore, since the coordinates of the vertex of this parabola are (2,4), and it is "squeezed" by a factor of 2, the correct answer is C. Hope this helps!
Answer: D) No; If x is 5, the expression on the left simplifies to 8, making the inequality false.
In other words, if x = 5, then x+3 becomes 5+3 which ultimately becomes 8, but this is not greater than 8 on the right side.
Your steps could look like this
x+3 > 8
5+3 > 8 ... replace x with 5
8 > 8 ... this is a false inequality
P= 3000 (1.21)^t, t= time in months
1 year = 12 months, and therefore, 1 month = 1/12 years
The equation showing yearly population growth changes to;
P=3000 (1.21)^t/12
The correct answer is equation [1].
.19 thats the answer if you do the problem good luck<span />
1. 5 -4x =6 +2x
+4x. +4x
5=6. +6x
-6 -6
-1 = 6x

6. 6
-6=x
2. 9 - 2x = 7x
+2x. +2x
9 = 9x
