Answer:
f(x) = 150-25x
Step-by-step explanation:
200-50=150.
Take the 150 and insert it there.
Each lesson is $25, so you multiply 25 by 2 every lesson. Example= 150-25=125-25=100-75 and so on.
Y=-1/20(x+3)^2
Your could always tell by which way the curve is pointing and if pointing down it’s a negative it’s pointing up it’s a positive
Hope that helped
Answer:
A
Step-by-step explanation:
Because we are reflecting across the X-axis, the X coordinate does not change. On the other hand, the Y coordinate becomes its opposite. So we get:
(2, 4) -> (2, -4)
They met 480 meters from the house.

Given that Noah and his grandfather were returning home from a walk, and when they were 800 m away from the house, the grandfather said that he was thirsty, so Noah immediately ran home, got a bottle of water, and ran back to meet his grandfather who never stopped walking at a steady pace, to determine how many meters from the house did they meet if noah ran four times as fast as his grandfather walked, the following calculation must be made:
- 200 x 4 = 800 - 200 = 600
- 300 x 4 = 1200 - 800 - (800 - 300) = 100
- 325 x 4 = 1300 - 800 - (800 - 325) = -25
- 320 x 4 = 1280 - 800 - (800 - 320) = 480 - 480 = 0
Therefore, they met 480 meters from the house.
