zhannawk [14.2K]

Answer:

well the sum of all the fraction combined are 2.05, so you could fill 2 1/2 drawers. So technically you could use 3 drawers, but the 3rd one won't be full.

What is an equation of the line perpendicular to y=-x-2 and through (-2, 4)?
Salsk061 [2.6K]

Answer: y = x + 6

Step-by-step explanation:

\mathrm{Find\:the\:line\:}\mathbf{y=mx+b}\mathrm{\:perpendicular\:to\:}y=-x-2\mathrm{\:that\:passes\:through\:}\left(-2,\:4\right)

\mathrm{For\:a\:line\:equation\:for\:the\:form\:of\:}\mathbf{y=mx+b}\mathrm{,\:the\:slope\:is\:}\mathbf{m}

m=-1

\mathrm{The\:perpendicular\:slope\:is\:the\:negative\:reciprocal\:of\:the\:given\:slope}

\left(-1\right)m_p=-1

\frac{\left(-1\right)m_p}{-1}=\frac{-1}{-1}

m_p=1

\mathrm{Compute\:the\:line\:equation\:}\mathbf{y=mx+b}\mathrm{\:for\:slope\:m=}1\mathrm{\:and\:passing\:through\:}\left(-2,\:4\right)\mathrm{Plug\:the\:slope\:}1\mathrm{\:into\:}y=mx+b

y=x+b

\mathrm{Plug\:in\:}\left(-2,\:4\right)\mathrm{:\:}\quad \:x=-2,\:y=4

4=\left(-2\right)+b

-2+b=4

\mathrm{Add\:}2\mathrm{\:to\:both\:sides}

-2+b+2=4+2

\text{Simplify}

b=6

\mathrm{Construct\:the\:line\:equation\:}\mathbf{y=mx+b}\mathrm{\:where\:}\mathbf{m}=1\mathrm{\:and\:}\mathbf{b}=6

y=x+6

A system of linear inequalities is shown above. ( in the picture )
astraxan [27]

Answer:

C. (0, -3)

Step-by-step explanation:

The given system is

- 2x - 3 \leqslant y

y - 1 \:  <  \:  \frac{1}{2} x

The point that satisfies both inequalities is the solution to the system.

When x=0 and y=-3.

We substitute into the first inequality to get:

- 2(0) - 3 \leqslant  - 3 \\  - 3 \leqslant  - 3...true

We again substitute into the second inequality to get:

- 3- 1 \:  <  \:  \frac{1}{2} (0) \\  - 4 \:  <  \: 0....true

The point (0,-3) is a solution to the system of inequalities.
