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).}

A function assigns the values. The range of the function will be between (-∞,10].

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The given function f(x)=10-x² is a parabolic function that is negative, therefore, will open downwards. Now, the range of the function can be found as,

f(x)=10-x²

y=10-x²

y-10 = -x²

-y+10 = x²

-y + 10 = 0

y = 10

Thus, the range of the function will be between (-∞,10].

The correct answer is D. D'(1, 5), E'(-1, 3), F'(-1, -4), G'(1, -2).

It's because of this: You need to calculate the distances, and they are in this case symmetric, so you look how far is from one side, and it will be the same on the other side. When you put it on graph, the coordinates are clear and the correct answer is D.
