jeka94

Answer: r - 5 = 8

Step-by-step explanation:

From the question, we are informed that Skye ran r laps today at soccer practice while Nadine ran five fewer laps than Skye.

If Nadine ran eight laps at practice, the equation that can be used to find how many laps Skye ran will be:

r - 5 = 8

This means Skye ran 13 laps

Consider the line y=-3x+3.

Answer:

$y= 3x+17; y= -\frac13x +\frac{11}3$

Step-by-step explanation:

First problem. If you want a parallel to a given line, you keep the slope.

Then we use the point-slope form of a line

$y-y_0=m(x-x_0)$ and we plug in there everything we need.

$y-5=3(x+4) \rightarrow y=3x+12+5\\y=3x+17$

The second is quite similar. This time we want the perpendicular. It means that the product of the slopes has to be -1.

$3\cdot m = -1 \rightarrow m=-\frac13$

At this point we have everything, let's replace and write down the line in a better looking form

$y-5=-\frac13(x+4) \rightarrow y= -\frac13 x -\frac43 +5\\y= -\frac13x -\frac43 +\frac{15}3 \rightarrow y= -\frac13x +\frac{11}3$
