Answer:

x = 8.75, y = 8.125

Step-by-step explanation:

The triangles are similar thus the ratios of corresponding sides are equal, that is

\frac{8}{5} = \frac{14}{x} ( cross-  multiply )

8x = 70 ( divide both sides by 8 )

x = 8.75

And

\frac{8}{5} = \frac{13}{y} ( cross- multiply )

8y = 65 ( divide both sides by 8 )

y = 8.125

Anna71 [15]

Answer: (4,-5)

Step-by-step explanation:

8y = -40

(divide by 8)

y = -5

(plug it in to one of the equations)

3x + 6*-5 = -18

3x + -30 = -18

3x = 12

x = 4

Witch set of orderd pairs contains only points that are on the graph of the function y=12-3x
anygoal [31]
You can try then by plotting the points in. 
The answer is C

Make sure by plotting in the points, lets take (-5,27)
y = 12 -3(-5)
y = 12 + 15
y = 27
27 = 27
This is correct 

Lets try (-1,15)
y = 12 -3(-1)
y = 12 + 3 
y = 15 
15 = 15
This is correct 

Lets try (8,-12)
y = 12 -3(8)
y = 12 - 24 
y = -12 
-12 = -12
This is correct too. 

The correct ordered pairs are <span>C(-5,27),(-1,15),(8,-12)</span>
