3 seconds
solve for when y is zero
0 = -16t^2 + 32t + 48
0 = -16(x^2-2x-3)
0 = -16(x-3)(x+2)
x = 3 or -2
-2 is extraneous because time is not negative in this instance so 3 seconds.

Answer: x=1.6
y=4.2
Step-by-step explanation:
5.2x - y = 4.1
1.5x + y = 6.7
we will add both equations and you see that the y is getting cancelled
6.7x=10.8
x=10.8/6.7= 1.6
now in any equation we will replace x with 1.6
5.2(1.6)-y=4.1
8.3-y=4.1
-y= 4.1-8.3
-y=-4.2 multiply by -1
y=4.2

Answer:
-1
Step-by-step explanation:
-2(x-7)=16
-2x +14=16 You distribute
-14 -14
-2x = 2
-2 -2 you divide
and get -1 as your answer.
Hope my answer has helped you!
