Answer:

y +5 = (-2/3)(x -4)

Step-by-step explanation:

The point-slope form of an equation of a line with slope m through point (h, k) is ...

... y -k = m(x -h)

You have (h, k) = (4, -5) and a slope the same as that of the parallel line, m = -2/3. Then the equation is ...

... y -(-5) = (-2/3)(x -4)

... y +5 = (-2/3)(x -4)

If the sides of a parallelogram are increased to twice its original lengths, how much will the perimeter of the new parallelogra

inna [77]

Answer:

2 times

Step-by-step explanation:

the length and breadth of the parallelogram will be l and b, respectively.

Then, perimeter = 2(1 + b) [∵ perimeter of parallelogram = 2 x (length + breadth)]

If both sides are increased twice, then new length and breadth will be 21 and 2b, respectively.

Now, new perimeter = 2(21 + 2b) = 2 x 2(l + b) = 2 times of original perimeter.

the perimeter of parallelogram will be increased 2 times.

Kobotan [32]

Answer:

2.56 gallons per minute!

Step-by-step explanation:

44.8 gallons - 32 gallons = 12.8 gallons

12.8 gallons in 5 minutes - so we need to find the unit rate (per one minute)

12.8/5 = 2.56

2.56 gallons per minute!

Answer:

24 in long by 12 in wide.

Step-by-step explanation:

l=2w

288=(2w)×w

288=2w^2

144=w^2

12=w

use w=12 to solve for l

l=2(12)

l=24
