0 = -16t² + 36t + 4
0 = -8t² + 18t + 2 ← Complete the square to solve
-8(t² - 9t/2) = -2
8(t² - 9t/4 + 81/64) = 2 + 81/8
8(t - 9/8)² = 97/8
(t - 9/8)² = 97/64
t - (t = 0)

Answer:
d) move 7 units right and 3 units down.
Step-by-step explanation:
From (0,0) which is the origin, move 7 units right. Right now it would be (7,y). Then move 3 units down which would be (7,-3)
Answer: 40
Step-by-step explanation:
First find what 57 seconds in minutes is, 57 seconds equals 0.95 minutes
And then do distance/time=speed
38/0.95=40 m/min
The answer would be 5.794.
The thousandths place is where the 3 is. If the number to the right of it is 5 or bigger, than you can round up. If not, then you round down.
It would be 150 miles
equation: y = 30x
