Given a dilation around the origin, what is the scale factor K?

kobusy [5.1K]

Answer:

The answer is " $\frac{4}{3}$ "

Step-by-step explanation:

Given:

$\bold{DoK = (12, 8) (9,6)}$

In the scale factor when we take x coordinate then the value of k is:

$\Rightarrow x= \frac{x_1}{x_2}\\\\\Rightarrow x= \frac{12}{9}\\\\\Rightarrow x= \frac{4}{3}\\$

If we take y coordinate then the value of k is:

$\Rightarrow y= \frac{y_1}{y_2}\\\\\Rightarrow y= \frac{8}{6}\\\\\Rightarrow y= \frac{4}{3}\\$

So, the final value of k is " $\frac{4}{3}$ " .

Which is the graph of the system of equations?<br> x + 2y = 2<br> 4x - y = 4

Sladkaya [172]

Solve for x for x: x+2y=2
x+2y +-2y=2+-2y (add -2y on both sides.)
x=-2y+2
Substitute : -2y+2 for x in
4x-y=4:
4(-2y+2)-y=4
-9y+8=4 Simplify both sides of the equation.
-9y+8+-8=4+-8 Add -8 to both sides.
-9y=-4
-9/-9=-4-9 Divide both sides by -9
y=4/9
Substitute 4/9 for y in
x=-2y+2
x=-2(4/9)+2
x=10/9
y=4/9,x=10/9

How can you find the slope of a line and use it to<br> solve problems?

ziro4ka [17]

Answer:

Step-by-step explanation:

1) Mark two points on the line in the graph.

2) Determine the rise and run. Rise ---> difference in y-coordinates. (y2-y1)

Run -----> difference in x-coordinates (x2 - x1)

3) Plugin the values in the below mentioned formula.

$Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

1.If slope = 0, then the line is parallel to x-axis.

2. If slope is undefined, then the line is parallel to y-axis.

3. If slope is +ve, then the line slant upwards and if slope = -ve, then the line slant downwards.
