So just plug in the 4 wherever you see an x. so it is f(4)=2(4)

On a coordinate grid, both point (−4, −1) and (2, 6) point are reflected across the y-axis. What are the coordinates of the refl

Reptile [31]

Answer:

Step-by-step explanation:

So first, we know (-x,-y) reflected across y axis is (x,-y). and (x,y) reflected across y axis is (-x, y). So we can apply this to get (-4,-1) to (4,-1). (2,6) to (-2,6).

Find the rectangular coordinates of the point. (-5, -180°)

o-na [289]

$\bf \begin{array}{rlclll}
(-5&,&-180^o)\\
\uparrow &&\uparrow \\
r&&\theta 
\end{array}\quad 
\begin{cases}
x=rcos(\theta )\\
\qquad -5\cdot cos(-180^o)\\
\qquad -5\cdot -1\\
\qquad 5\\
----------\\
y=rsin(\theta )\\
\qquad -5\cdot sin(-180^o)\\
\qquad -5\cdot 0\\
\qquad 0
\end{cases}\implies (5,0)$
