Find the equation of the line that is perpendicular to y = 1/4 x – 2 and passes though the point (5, –2).
zlopas [31]

\textsf{Let y = ax + b the line we want to find.}

\textsf{We know that the slope of y = ax + b is the inverse of the slope of } \mathsf{ y = \frac{1}{4}x - 2.}

\textsf{Thus:}

\mathsf{a = \dfrac{1}{\frac{1}{4}} = 4}

\textsf{As y = 4x + b passes thought (5, -2):}

\mathsf{-2 = 4 \cdot 5 + b  \Rightarrow 20 + b = -2 \Rightarrow b = -22}

\textsf{Hence the line y = 4x - 22 is perpendicular to }\mathsf{y=\frac{1}{4}x - 2}\textsf{ and passes for the point (5, -2).}

(5+6b^3)^2 expand and combine like terms
Drupady [299]

Answer:

( 5 + 6b^3)^2 = 36b^6 + 60b^3 + 25

Step-by-step explanation:

(a + b)^2 = a^2 + b^2 + 2ab

So,

        (5 + 6b^3)^2 = (5)^2 + (6b^3)^2 + 2 (5)(6b^3)

                       = 25 + 36b^6 + 60b^3

Which functions are symmetric with respect to the y-axis? Check all that apply.
xenn [34]

Answer:

f(x) = |x|, f(x) = [x] + 6

Step-by-step explanation:

Almost all of these are absolute values equations, which means the y doesn't change if x is positive or negative. The first one is the parent form, which is the simplest equation of the absolute equation, so it's symmetric with respect to the y-axis. The second equation is translated 3 units to the left, and the third is translated 31 to the left. The forth is translated 6 up, so it's still symmetric with respect to the y-axis. The fifth is translated 61 units left, and the last one is simply a line, which isn't symmetric.
