To find when the ball reaches the ground, you would need to find the time that gives you a height value of zero.
Your answer would be 4 seconds
h = -16(4)^2 + 64(16)
h = -16(16) + 256
h = -256 + 256
h = 0
Hope this helps!
D. y=5x+6 and 2y-12-10x=0 has infinitely many solutions and both lines are linear
E. y=4x+1, y=9x+4 has the solutions x = -3/5, y = -7/5
Answer:
Step-by-step explanation: you just need to find the greatest factors and least multiple then do it to two numbers
Answer:
its the last one
Step-by-step explanation:
Answer:
(a)
(b)
Step-by-step explanation:
(a) can also be written as x
the = ± y
Therefore :
= ±
since it was given that y < 0 , then the factor will be
(b) can also be written as : x
Therefore , one of the factor is
