Factor completely. y2 - xy - 56x2

1 answer:

5 0

For this case we have the following expression:
y2 - xy - 56x2
Rewriting we have the factored expression, which is given by:
(7x + y) (y-8x)
Checking we have:
7xy - 56x ^ 2 + y ^ 2 - 8xy
y ^ 2 - xy - 56x ^ 2 (OK)
Answer:
The factored expression is given by:
y2 - xy - 56x2 = (7x + y) (y-8x)

Can anybody solve this equation?<br>Y = 39.95x +25

umka21 [38]

Answer:

(y - 2647.7) = 39.95(x - 6)

y - 264.7 = 39.95x - 239.7

y = 39.95x - 239.7 + 264.7

y = 39.95x + 25

Determine the volume of the space in the tank that still needs to be filled with water if the water is ⅓ ft. Deep

vlada-n [284]

Answer:

11 1/9 ft^3

Step-by-step explanation:

find the complete question in the attached image

volume of the tank = length x width x height

2 x 5 x 1 2/3

2 x 5 x 5/3 = 50/3 = 16 2/3 ft^3

If the tank is 1/3 filled with water, the volume that needs to be filled with water is 1 - 1/3 = 2/3

volume that needs to be filled with water = 2/3 x volume of the tank

2/3 x 50/3 = 11 1/9 ft^3

HELPPP!!! Write the equation for the function on the right.

Sergeu [11.5K]

Answer:

It is moved 8 units left and 5 units down

y = $\sqrt[3]{x+8}$ - 5

So vertical translation 5 units down and horizontal translation 8 units left
