Answer: -5x + 8 - 6y

Step-by-step explanation:

<u>Given expression</u>

-2 (x - 4) - 3 (x + 2y)

<u>Expand parentheses and apply the distributive property</u>

= -2x + 8 - 3x - 6y

<u>Combine like terms</u>

= (-2x - 3x) + 8 - 6y

= \boxed{-5x+8-6y}

Hope this helps!! :)

m_a_m_a [10]
Answer: 11:12 PM.
explanation:
- 10% of 8 is 0.8. (10% is 0.1, and you multiply this by 8)
- multiply 0.8 by 60 so you can get the number of minutes before midnight (this is 48).
- 48 minutes before midnight is 11:12.

the system of equations is graphed on the coordinate plane y=-1/2x-1 and y=1/4x-4 enter the coordinates of the solution to the s
pochemuha

Answer:

The coordinates are ( 4, -3).

Step-by-step explanation:

We can find the coordinates by solving the 2 equations

y =  1/4x-4

y = -1/2x-1

As both left sides of the equation are y we can say:

-1/2x-1 = 1/4x-4

-1/2x - 1/4x = -4 + 1

-3/4 x = -3

x = -3 * -4/3

x = 4.

- and y = 1/4(4) - 4 = -3.

\displaystyle\\&#10; -3\tan^2x + 1 = 0\\\\&#10; -3\tan^2x = -1\\\\&#10;\tan^2x =  \frac{-1}{-3} \\\\&#10;\tan^2x =  \frac{1}{3} ~~~~~ \Big|~\sqrt{~~~} \\\\&#10;\sqrt{\tan^2x} =  \sqrt{\frac{1}{3}} \\\\&#10;\tan x = \Big| \frac{1}{ \sqrt{3} } \Big|\\\\&#10;\tan x = \Big| \frac{\sqrt{3}}{ 3 } \Big|\\\\&#10;\tan x =  \frac{\sqrt{3}}{ 3 }~~~\Longrightarrow~~x_1=  \frac{\pi}{6} + k\pi,~~k \in N \\\\  &#10;\tan x =  -\frac{\sqrt{3}}{ 3 }~~~\Longrightarrow~~x_2=  \pi-\frac{\pi}{6} + k\pi = \frac{5\pi}{6} + k\pi,~~k \in N \\\\  &#10;
