What is the image of (9,3) after a dilation by a scale factor of 3 centered at the<br> origin?
sergiy2304 [10]

Answer:  (27, 9)

Multiply the original coordinates by the scale factor 3 to get this answer

9*3 = 27

3*3 = 9

This only works if the center of dilation is the origin.

The general rule is (x,y) \to (kx, ky) where k is the scale factor.

Which linear function is represented by the graph?
professor190 [17]

9514 1404 393

Answer:

 f(x) = -1/2x +1

Step-by-step explanation:

The line crosses the y-axis at y=1, so the y-intercept is b=1.

The line drops 1 unit for a run of 2 to the right, so the slope is ...

  m = rise/run = -1/2

The slope-intercept form of the equation of the line is ...

  y = mx + b

  y = -1/2x + 1

In functional form, the equation is ...

  f(x) = -1/2x +1

What is the average rate of change from -3 to 0 of the function represented by the graph?
lbvjy [14]

Average rate of change = change in y ÷ change in x

We already know the change in x because we are measuring the x values from -3 to 0.

change in x = 0-(-3) = 3

To find the change in y find the difference between the corresponding y-values when x=0 and when x=-3.

change in y = 0.5-2 = -1.5

average rate of change = -1.5/3 = -0.5

answer: -0.5

larisa [96]

To find the area of the larger figure, let's multiply the length by the width.

9 ft * 4 ft = 36ft^2

Let's do the same thing with the smaller figure.

3 ft * 4 ft = 12ft^2

Let's add the area of both figures together.

36ft^2 + 12ft^2 = 48ft^2
