Answer:
2400m³
Step-by-step explanation:
50 * 30 * 1.6 =
1500 * 1.6 = 2400m³
10x + 2y = -2
2y = -10x -2
y = -5x - 1 (slope is -5 and a parallel line will have the same slope)
y = mx + b
slope(m) = -5
12 = -5(0) + b
12 = 0 + b
12 = b
so the parallel line is y = -5x + 12
hope this helps, God bless!
We have the expression:
![4y+10](https://tex.z-dn.net/?f=4y%2B10)
And want to evaluate in y=5, this means we have to replace y in the expression for 5 and calculate the value of the expression, so:
![\begin{gathered} 4y+10,y=5 \\ 4\cdot5+10 \\ 20+10 \\ 30 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%204y%2B10%2Cy%3D5%20%5C%5C%204%5Ccdot5%2B10%20%5C%5C%2020%2B10%20%5C%5C%2030%20%5Cend%7Bgathered%7D)
The expression is 30 when y=5.
Your answer will be 1,000.3125
hope i helped!! :)
