Graph the solution to the system<br> -x+y>2<br> X+2y>2

mariarad [96]

Answer:

$\begin{bmatrix}y>2+x\\ y>\frac{2-x}{2}\end{bmatrix}$

Step-by-step explanation:

<u>Step 1: Solve the system of equations</u>

<u /> $\begin{bmatrix}-x+y>2\\ x+2y>2\end{bmatrix}$ <u />

Isolate $y$ for $-x+y>2$

$\mathrm{Add\:}x\mathrm{\:to\:both\:sides}$

$-x+y+x>2+x$

$y>2+x$

Isolate $y$ for $x+2y>2$

$\mathrm{Subtract\:}x\mathrm{\:from\:both\:sides}$

$2y>2-x$

$\mathrm{Divide\:both\:sides\:by\:}2$

$\frac{2y}{2}>\frac{2}{2}-\frac{x}{2}$

$y>\frac{2-x}{2}$

$\bold{=\begin{bmatrix}y>2+x\\ y>\frac{2-x}{2}\end{bmatrix}}$

<u>Step 2: Graph</u>

Instructions for graphing:

$\mathrm{1.\:Graph\:each\:inequality\:separately.}$

$\mathrm{2.\:Choose\:a\:test\:point\:to\:determine\:which\:side\:of\:the\:line\:needs\:to\:be\:shaded.}$

$3. \mathrm{The\:solution\:to\:the\:system\:will\:be\:the\:area\:where\:the\:shadings\:}\\\mathrm{from\:each\:inequality\:overlap\:one\:another.}$

When done, it should look like this:

In the figure below, △ A B C ∼△ D E F . BX and EY are altitudes of each triangle. Find the measure of EY to the nearest tenth.

Elena-2011 [213]

Answer:

EY = 5.3 cm

Step-by-step explanation:

∵ Δ ABC similar to ΔDEF

∴ AB/DE = BX/Ey

∵ AB = 12 cm

∵ DE = 8 cm

∵ BX = 8 cm

∴ 12/8 = 8/EY

∴ 12EY = 8 × 8 ⇒ 12AY = 64

∴ EY = 64 ÷ 12 = 5.3333 ≅ 5.3 cm
