Step-by-step explanation:

81x⁴ - 16y⁴

(9x²)² - (4y²)²

(9x² + 4y²)(9x² - 4y²)

(9x² + 4y²)(3x + 2y)(3x - 2y)

What is the correct answer of 1/3
serious [3.7K]
The correct answer of 1/3 is the decimal form of it which is 0.3 repeated (you can put a line on top of the 3). If not just leave it as 1/3 it is simplified as a fraction.

Suppose y varies directly with x. Write a direct variation equation that relates x and y. Then find the value of y when x=12
lidiya [134]

Answer:

Step-by-step explanation:

If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable.

Given that y varies directly with x, if we introduce a constant of proportionality, k, the expression becomes

y = kx

If y = 8 when x = 3, then

8 = 3k

k = 3/8

Therefore, the direct variation equation that relates x and y is

y = 3x/8

When x = 12, then

y = 3 × 12/8

y = 4.5
