Answer:
The answer is the option B
It is wider and shifted units to the right
Step-by-step explanation:
we have
The vertex of the function is the point
The vertex of the function is the point
The function is wider than the function
Because it is multiplied by a number less than
The rule of the translation is
That means
The translation is units to the right

Answer:
The speed of the biker is 15
Step-by-step explanation:
First, you call the speed of the walker x, and the speed of the biker 2.5x.
Then you know that speed times time equals distance, so you set up and equation. You do x times 2, which is 2x, and then 2.5x times 2, which is 5x. Then, since the distance between them is 18 miles, the equation would be 5x-2x=18. You would get 3x=18, and x is 6. So 6 is the speed of the walker, and 6 times 2.5 = 15, so the speed of the biker is 15.
just subtracting by 2x on both sides
hope this helps
