2x +3x = 180
5x = 180
x = 36
I believe it would be multiplied by -0.5 or -1/2.
Answer:
The answer to your question is: 1
Step-by-step explanation:
f(0) = 1 , because when x = 1, y = 1
It gives function: h = -16t^2 + 40
water is when height is 0 so solve for 0= -16t^2 + 40
subtract 40 from both sides: -40 = -16t^2
divide by -16: -40/-16 = t^2
simplify: 5/2 = t^2
square root both sides: 1.58 = t
