5z>15-----subtract 2 on both sides
z>3----divide by 5
therefore, z must equal -10, or -4
Answer:
Step-by-step explanation:
assuming that the X is a multiplication symbol and not a variable, because the multiplication symbol is * not x, 5*5/2*7=25/14=1 and 11/14
A.) y = ut - 1/2gt^2 + 12
y = 6t - 1/2(9.8)t^2 + 12
y = 6t - 4.9t^2 + 12
b.) The y-intercept is 12
c.) The y-intercept represent the height of the ball at time t = 0
d.) At the time the ball reaches the ground, y = 0
-4.9t^2 + 6t + 12 = 0
t = 2.29 seconds
Therefore, it took the ball 2.29 seconds to reach the ground.

Answer:
549
Step-by-step explanation:
A calculator can give you an equivalent expression.
I might work from the middle outward:
= 486 -3 +33×2
= 483 +66
= (480 +60) + (3 +6)
= 540 + 9
= 549
