Answer:

A. intersecting


Step-by-step explanation:

write the equations in the from of y = mx + c

Where m = slope

            c = y-intercept.

1/3x + y + 2 = 0

1/3x + y = -2

y = -1/3x - 2

1/2x + y - 5 = 0

1/2x + y = 5

y = -1/2x + 5

The equations are not parallel

-1/3x - 2 = -1/2x + 5

1/2x - 1/3x = 5 + 2

1/6x = 7

x = 7× 6/1

   = 42

y =  -1/3×42 -2

  = -14 - 2

 = -16

The equations intersect at point (42,-16)

timama [110]

Answer:

Jay's bread size is 220% of the original size.

Step-by-step explanation:

The question is incomplete.

The complete question is as follows.

Jay is letting her bread rise. After 3 hours,her bread is at 11/5 of its original size. What percent of its original size is jays bread dough?

Solution:

Let the original bread size be = 100 units

After 3 hours the bread rises = \frac{11}{5} of the original size

New size of bread =  \frac{11}{5}\times 100=220 units

Percent of original size the new bread is

⇒ \frac{New\ bread\ size}{Original\ bread\ size}\times 100

⇒ \frac{220}{100}\times100

⇒ 220\%
