Answer: $\textsf{y = -2/5x}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{Passes through (5, -2) and slope of -2/5}$

Find: $\textsf{The equation that follows the details provided}$

Solution: We first need to plug into the point-slope form and after simplifying, distributing, and solving for y we will complete our equation.

Plug in the values

$\textsf{y - y}_1\textsf{ = m(x - x}_1\textsf{)}$

$\textsf{y - (-2) = -2/5(x - 5)}$

Distribute and simplify

$\textsf{y + 2 = -2/5(x - 5)}$

$\textsf{y + 2 = (-2/5 * x) + (-2/5 * (-5))}$

$\textsf{y + 2 = -2/5x + 2}$

Subtract 2 from both sides

$\textsf{y + 2 - 2 = -2/5x + 2 - 2}$

$\textsf{y = -2/5x + 2 - 2}$

$\textsf{y = -2/5x}$

Therefore, the final equation that follows the information that was provided is y = -2/5x.

Which of the following numbers is both a perfect square and a perfect cube?

Marat540 [252]

Answer:

531441

Step-by-step explanation:

We can find by factorization

531441 = 9 * 9 * 9 * 9 * 9 *9 = (9*9*9) * (9*9*9)

$\sqrt[3]{531441}=\sqrt[3]{9*9*9*9*9*9} =9*9 = 81\\\\\\\sqrt{531441}=\sqrt{(9*9)*(9*9)*(9*9)}=9*9*9=729$
