Answer:
y=8
Step-by-step explanation:
first you want to subtract 2y from 10y which will give you 8y and then divide both sides by 8 to get y alone and you will get y=8
The answer of this question is A. -112
-28/9-(-5 5/9)
-28/9-(50/9)
-28/9-50/9
22/9
= 2 4/9= 2.444444
hope this helps!
Answer:
4800m³
Step-by-step explanation:
V=
=
=4800
the maximum height is the y-value of the vertex.
h(x) = -2x² + 20x + 48
<em> a=-2, b=20, c=48</em>

h(5) = -2(5)² + 20(5) + 48
= -50 + 100 + 48
= 50 + 48
= 98
Answer: 98 meters
