You combine like terms like 8y+13y which gives you 21y and don't forget the -5x so your simplified equation would end up being A. 21 - 5x

Answer:
The answer is B ⇒ ![\sqrt{\frac{V}{15\pi }}=10](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7BV%7D%7B15%5Cpi%20%7D%7D%3D10)
Step-by-step explanation:
∵ v = π r² h
∴ r² = ![\frac{V}{\pi h }](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7B%5Cpi%20h%20%7D)
∴ r = ![\sqrt{\frac{V}{\pi h}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7BV%7D%7B%5Cpi%20h%7D%7D)
∵ r = 10 ft and h = 15 ft
∴ ![10=\sqrt{\frac{V}{15\pi } }](https://tex.z-dn.net/?f=10%3D%5Csqrt%7B%5Cfrac%7BV%7D%7B15%5Cpi%20%7D%20%7D)
Answer:
y = ![\frac{5}{3}x-1](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7Dx-1)
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here m = slope of the line
b = y-intercept
Slope of a line passing through two points
and
is,
m = ![\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
From the graph attached,
Since, the given line passes through (0, -1) and (3, 4),
Slope 'm' = ![\frac{4+1}{3-0}](https://tex.z-dn.net/?f=%5Cfrac%7B4%2B1%7D%7B3-0%7D)
m = ![\frac{5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7D)
y - intercept 'b' = -1
Therefore, equation of the line will be,
y = ![\frac{5}{3}x-1](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7Dx-1)
