If you take 230 subtract from 180 you will get 50 so the price for adult tickets are $50
f(0) means x = 0
so when x = 0, y = -5
and when x = 4, f(4) is also equal -5 (y = -5)
so f(0) = f(4) = -5
Answer
D) f(4)
Answer: 54
Explanation step by step: according to bidmas you must open the bracket first before any other thing. so the solution is 5×5-7×3
Answer:
Step-by-step explanation:
Okay, so hopefully my crude diagram helps you visualize the problem. When in doubt, always draw a picture.
All I did was graph the points and formed a line.
Slope: It's going to be 0 because it doesn't change at all (no different y values)
(y2-y1)/(x2-x1) = (6-6) / (4-2) = 0/2 = 0
Y intercept is where the line crosses the y axis- this is also where x=0 (find it in your chart!)
Equation is y= 6; I don't know how to explain this, but trust me, it's right
He has 21 classmates, you know this by, taking 17.5 and dividing it by the 5/6. This leading to get you 21.
