Answer:
Yes it is a rational number. (There are no explanations)
Step-by-step explanation:
The vertex at (1,2) and from there use this to make the graph.
over 1, up 1. over 2 up 4, over 3 up 9. and if you know its right side, you know its left side too.
After 5 years, value doubles.
Hence after 5 years, value is 250 x 2 = 500
After another 5 years, value doubles.
500 x 2 = 1000
Ans: $1000
Method 2, using function given.
v(10) = 250 x 2(10/5) = $1000
The answer is B. They did not multiply the constant 2 by 4 when multiplying through to remove the fraction. so the correct answer would be x-4y=-8
