The image of (6, 9) under a dilation is (4, 6). The scale factor is 0-2 O 2/3 0 -2/3

lisov135 [29]

Answer:

$\frac{2}{3}$

Step-by-step explanation:

To determine the scale factor consider the ratio of the image coordinates to the original coordinates, that is

scale factor = $\frac{4}{6}$ = $\frac{6}{9}$ = $\frac{2}{3}$

Solve the system of equations using elimination.

Andrej [43]

Answer:

{x = 3, y = 9 thus Answer A is correct

Step-by-step explanation:

{5 y - 7 x = 24 | (equation 1)

{5 y - 9 x = 18 | (equation 2)

Swap equation 1 with equation 2:

{-(9 x) + 5 y = 18 | (equation 1)

{-(7 x) + 5 y = 24 | (equation 2)

Subtract 7/9 × (equation 1) from equation 2:

{-(9 x) + 5 y = 18 | (equation 1)

{0 x+(10 y)/9 = 10 | (equation 2)

Multiply equation 2 by 9/10:

{-(9 x) + 5 y = 18 | (equation 1)

{0 x+y = 9 | (equation 2)

Subtract 5 × (equation 2) from equation 1:

{-(9 x)+0 y = -27 | (equation 1)

{0 x+y = 9 | (equation 2)

Divide equation 1 by -9:

{x+0 y = 3 | (equation 1)

{0 x+y = 9 | (equation 2)

Collect results:

Answer: {x = 3, y = 9

The points given in the table above lie on a line. Find the slope of the line.

pantera1 [17]

Answer:

Step-by-step explanation:

When given points, whether that be on a graph or a table, those can be used to find the slope using the equation y2 - y1 / x2 - x1.

y2 - y1 / x2 - x1

(Pick 2 pairs if points. In this case I am using (2, -1) and (-1, 3) from your data table. From here, just plug it in.

-1 - 3 / 2 + 1

-4 / 3

Your slope is -4/3. Hope that helps! Take care.
