What are the coordinates of R' for the dilation D(0.5. p)(PQRS)?

11111nata11111 [884]

Answer:

$R' = (-1,-0.5)$

Step-by-step explanation:

See attachment for complete question.

From the attachment:

$P = (-3,-3)$

$R = (1,2)$

Dilation:

$D_{(0.5,P)}$

Required

Determine R'

First, subtract the coordinates of P from R. This means that R is measured from P.

$R = (1-(-3),2-(-3))$

$R = (1+3,2+3)$

$R = (4,5)$

Next, apply dilation factor 0.5

$R' = R * 0.5$

$R' = (4,5) * 0.5$

$R' = (4* 0.5,5* 0.5)$

$R' = (2,2.5)$

Lastly, measure R' from the origin by adding the coordinates of P to R'

$R' = (2+(-3),2.5+(-3))$

$R' = (2-3,2.5-3)$

$R' = (-1,-0.5)$

Which system of linear inequalities is represented by the graph?

masha68 [24]

For the red line, we have:

gradient ( $m$ ) = 1/3
y-intercept = 3

Equation of straight line is given by $y=mx+c$ , where $m$ is the gradient and $c$ is where the line intercept the y-axis

So we have, $y= \frac{1}{3}x+3$

The shaded part is above the line, hence the first inequality is
$y \geq \frac{1}{3}x+3$

The black line, we have
gradient, $(m)$ = 3
y-intercept = -2

$y=mx+c$
$y=3x-2$ , rearranging gives
$3x-y=2$

The shaded region is to the right of the line, hence the inequality is
$3x-y\ \textgreater \ 2$

Note: The first option should be the correct answer but the inequality sign for <span>y > 1/3x + 3 should be </span> $\geq$
