Aweed called the boomstar vine is known for growing at a very fast rate. it can grow up to 0.5 feet per day. a. how fast in inches per day can the boomstar vine grow up to? b. how fast in inches per hour can the boomstar vine grow up to?

1 foot = 12 inches so 0.5 foot = 12*0.5 = 6 inches

A) it can grow 6 inches per day

B) 1 day = 24 hours

6 inches / 24 hours = 0.25 inches per hour

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

{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

answer:   {x = -1/2 ,   y = -1
