Select the descriptions that are true of the equation y - 6= - 3(x+2). Select all that apply.
Lapatulllka [165]

The point-slope form:

y-y_1=m(x-x_1)

We have

y-6=-3(x+2)\to y-6=-3(x-(-2))

Therefore

<h3>slope = -3 and the point (-2, 6)</h3>

------------

<h3>y + 2 = 2(x - 1)</h3>

2x - y = 4    <em>it's standard form Ax + By = C</em>

y = 2x - 4     <em>it's slope-intercept form y = mx + b</em>

y - x = 4 →<em> </em>x - y = -4  <em>t's standard form Ax + By = C</em>

Find the surface area of the triangular prism. Be sure to include the correct unit in your answer.
Montano1993 [528]

Answer:

174 CM²

Step-by-step explanation:

First we split up the triangular prism into shapes we can better understand (2 triangles, and 2 rectangles)

We solve the area of the triangles by using the formula to the area of a triangle (B·H÷2) 8·6÷2=24

There are 2 triangles therefore we get 2*24 which is 48 CM²

Now we calculate the area of the rectangles (7·10=70, 8·7=56)

Finally we add up all the numbers (70+56+48=174 CM²)

Therefore the surface area of the triangular prism is 174 CM², respectively.

Oksanka [162]
----------------------------------------
Find Monthly Income
----------------------------------------
Gross Annually Income = $43 908
Gross Monthly Income = $43 908 ÷ 12
Gross Monthly Income = $3659

----------------------------------------
Paycheck deducted for 401k
----------------------------------------
6% of $3659
= 0.06 x 3659
= $219.54
----------------------------------------
Employer contribution to his 401k
----------------------------------------
4% of $2659
= 0.04 x 3659
= $146.36

----------------------------------------
Total contribution to his 401k
----------------------------------------
$219.54 + $146.36 = $365.90

----------------------------------------
Answer: $365.90 (Answer C)

What is the solution of the matrix equation?
Alenkasestr [34]

Answer:

<h3>(-12, 2)</h3>

Step-by-step explanation:

\left[\begin{array}{ccc}1&1\\2&3\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] =\left[\begin{array}{ccc}8\\36\end{array}\right] \\\\\left[\begin{array}{ccc}x+y\\2x+3y\end{array}\right] =\left[\begin{array}{ccc}8\\36\end{array}\right]\\.\qquad\qquad\Downarrow\\\left\{\begin{array}{ccc}x+y=8&|\text{multiply both sides by (-2)}\\2x+3y=36\end{array}\right

\underline{+\left\{\begin{array}{ccc}-2x-2y=-16\\2x+3y=36\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\qquad y=20\\\\\text{Put the value of y to the firast equation:}\\\\x+20=8\qquad\text{subtract 20 from both sides}\\x=-12\\\\\boxed{(-12,\ 20)}
