Answer:

A. 3

Step-by-step explanation:

3x > 12 OR x + 1 ≤ -2

÷3 ÷3 OR - 1 -1

x > 4 x ≤ -3

This means that any number greater than four is a value for the solution. And any number equal to or less than -3 is part of the value for the solution.

D. -3 cannot be it because it is part of x ≤ -3

C. -5 cannot be it because it is part of x ≤ -5

B. 7 cannot be it because it is part of x > 4

A. 3 is true because it is not a part of either equation. So the answer is A.

I hope that this helps! :)

Find the equation of the line passing through the points (-2/3,1) and (-2,1/2). Write the equation in standard form.

7nadin3 [17]

Standard form is y = mx + b.
To find the slope, m, we must find the 'rise over run,' or the difference in y divided by the difference in x. We do this by:
$\frac{y1 - y2}{x1 - x2} = \frac{ (- \frac{2}{3} ) - ( -2 )}{(1) - ( \frac{1}{2} ) } = \frac{ \frac{4}{3} }{ \frac{1}{2} } \\ = \frac{4}{3} \times \frac{2}{1} = \frac{8}{3}$
Therefore, the slope is 8/3.

To find b, we must plug in the slope and one point:
$(1) = ( \frac{8}{3} )( - \frac{2}{3} ) + b \\ 1 = - \frac{16}{9} + b \\ \frac{25}{9} = b$
Therefore, b is 25/9, and the total equation is
$y = \frac{8}{3} x + \frac{25}{9}$

A cylindrical pressure vessel has a height of 9 feet and a diameter of 6 feet. How much gas can the pressure vessel hold when fu

notka56 [123]

since the diameter of the base of the cylinder is 6 feet, then its radius is half that, or 3 feet.

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\[-0.5em]
\hrulefill\\
r=3\\
h=9
\end{cases}\implies V=\pi (3)^2(9)\implies V=81\pi$

3m + 8 + m = 36 which can be substituted for m to make this equation true?

PilotLPTM [1.2K]

Answer:

m = 7

Step-by-step explanation:

3m + 8 + m = 36 , that is

4m + 8 = 36 ( subtract 8 from both sides )

4m = 28 ( divide both sides by 4 )

m = 7
