Answer:
-6.
Step-by-step explanation:
y = x - 6
y = 6x - 19
To eliminate x the first equation should be multiplied by -6 giving:
-6y = -6x + 36
Adding this to the second equation will eliminate x.
Answer:

Step-by-step explanation:
From the question we are told that:
Velocity 
The height h function

Generally time t is mathematically given by




Therefore the ball's maximum height is given as



I'll assume the question is: what's the volume?
It's two L×W×H rectangular prisms (aka boxes) put together
The bottom one is 2×3×4
The top one is 5×4×1
Volume = 2×3×4 + 5×4×1 = 24 + 20 = 44
Answer: 44 cubic feet
Because the triangle is only rotated, AB and A'B' would be equal. 8 in.
