Answer: The first option it would be raised to the power of x for x years this is because you don't know how many years x represents so you can't do 2 or some other number cause x could be 1000. Also its not multiplication because then it wouldn't double so
y=200^x
Step-by-step explanation:
The answer is y=2x+1. 1 being the y intercept and 2x being the slope
Answer:
D and B is the answer
Step-by-step explanation:
Here is a graph with the points
Given that the vertex (h, k) is (5, 2), you know the vertex form will look like
f(x) = a(x -5)² +2
for some value of "a" that makes f(4) = -3. That value of "a" can be found by substituting the given values in the above equation for f(x) and solving for "a".
-3 = a(4 -5)² +2
-3 -2 = a×1²
a = -5
This means the appropriate choice is ...
C) Vertex form: f(x) = -5(x -5)² +2; Standard form: -5x² +50x -123
This means that it is 8x-28=15+x. We let x equal the number. You can solve for the equation.
