Answer:

y ≥ -2

Step-by-step explanation:

5y - 3 ≥ -13

+3 +3

5y ≥ -10

5/5y ≥ -10/5

y ≥ -2

and since we didn't divide by any negative numbers the sign stays the same

8x+5y=24 y=-4x Solve for y and x

Cloud [144]

Answer:

x= -2 and y= 8

Step-by-step explanation:

8x+5y=24-------A

y=-4x---------B

Putting the value of y from B in A

8x+5(-4x)=24

8x +(-20x)= 24

8x-20x=24

-12x=24

x= -24/12

x=-2--------C y =-4(-2)=8

Please help. Thank you

Given:

$PQRS\sim TUVW$

In the given figure, PS=x, RS=35, UV=20, VW=25 and TW=15

To find:

The scale factor from PQRS to TUVW.

Solution:

We have,

$PQRS\sim TUVW$

We know that the corresponding sides of similar figures are proportional. The scale factor is the ratio of one side of image and corresponding side of preimage.

The scale factor is:

$k=\dfrac{VW}{RS}$

$k=\dfrac{25}{35}$

$k=\dfrac{5}{7}$

Therefore, the scale factor from PQRS to TUVW is $k=\dfrac{5}{7}$ .
