Solution
sin (90-x)=sin (90-50)
90-x=40⇒x=90-40
x=50.

Sin (90-x) = cos x

so x = 40

What is an equation of the line in point-slope form? How can the point-slope form be written in function notation?

harina [27]

The equation of a line in point slope form = $y - y_1 = m(x - x_1)$

To put $y - y_1 = m(x - x_1)$ into function notation, we need to get y by its self.
Lets say we had a point (2,2) and a slope of 3. Ok, now that we have our point and slope, lets turn point slope form into function notation.

$y - y_1 = m(x - x_1)$
$y - 2 = 3(x - 2)$
$y - 2 = 3x - 6$
$y = 3x - 6 + 2$
$y = 3x - 8$
Change the y to f(x)
$f(x) = 3x - 8$ <-----Function notation.

Question is: Solve -7(x+6)=4(x+6)

Alina [70]

$\huge\boxed{x=-6}$

Hey there! Our goal here is to isolate the variable on one side of the equation.

$\begin{aligned}-7(x+6)&=4(x+6)&&\smash{\Big|}&&\textsf{Start with the original equation.}\\-7x+(-7)(6)&=4x+4(6)&&\smash{\Big|}&&\textsf{Distribute.}\\-7x-42&=4x+24&&\smash{\Big|}&&\textsf{Multiply.}\\-7x-4x&=24+42&&\smash{\Big|}&&\textsf{Move the terms.}\\-11x&=66&&\smash{\Big|}&&\textsf{Combine like terms.}\\x&=\boxed{-6}&&\smash{\Big|}&&\textsf{Divide both sides by $-11$.}\end{aligned}$
