Hi KirstenTaylor17,

Your Question:

Leonardo da Vinci’s famous Mona Lisa occupies about 630 square inches of wall space. Candice buys a poster of the painting. The poster takes up 1750 square inches.

What was the scale factor for creating the poster?

Solution:

To find the scale factor just divide the bigger value from the smaller size.

1750 / 630 = 2.777777777777777777777778... = 2.78

D. 2.78

its easy all you have to do is divide the two numbers

1750/630 = 2.777777...etc

1750/630 = 2.78   (u have to round it)

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1
