$\bf i^3\implies \sqrt{-1}\cdot \sqrt{-1}\cdot \sqrt{-1}\implies (\sqrt{-1})^2\sqrt{-1}\implies \sqrt{(-1)^2}\cdot \sqrt{-1} \\\\\\ -1\cdot i\implies \boxed{-i}$

Write an equation that you can use to solve for x. Enter your answer in the box.

patriot [66]

X + 60 = 100 (because they are vertical angles, which means that because they are directly opposite of each other, they are of the same measurements).

Solve for x. Isolate the x, subtract 60 from both sides

x + 60 = 100

x + 60 (-60) = 100 (-60)

x = 100 (-60)

x = 40

40° should be your answer

hope this helps

Write the equation 5x - 3y = 15 in slope-intercept form. 5x____ - 3y = ____ + 15

Deffense [45]

5x - 3y = 15

5x - 5x -3y = - 5x + 15

-3y = -5x + 15

3y = 5x - 15

divide all of them by 3...

y = 5/3 - 5
