Graph the image of this figure after a dilation with a scale factor of 1/3

aliya0001 [1]

Answer:

(-1,1), (1,3), (2,2)

Step-by-step explanation:

To dilate an object, we need to multiply the x and y values by the given scale factor.

In this case the scale factor is 1/3 --> 1/3(x, y)

Before-> After dilation

1/3(-3,3) = (-1,1)

1/3(3,9) = (1,3)

1/3(6,6) = (2,2)

Please leave a 'thanks' if this helps!

Which orders paid is a solution is the equation y= 4x + 9

Verizon [17]

<em>Note: you did not add the answer options, so I am solving this question generally to solve your query, which anyways would clear your concept.</em>

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

$y= 4x + 9$

All we need is to find any random value of 'x' and then solve for 'y'.

For example, putting x=2

$y= 4x + 9$

$y=4(2)+9$

$y=8+9$

$y=17$

Thus, (2, 17) is one of the many ordered pairs solutions of the equation.

Similarly, putting x=3

$y= 4x + 9$

$y=4(3)+9$

$y=12+9$

$y=21$

Thus, (3, 21) is one of the many ordered pairs solutions of the equation.
