Answer:

b. no solution

$y = 2x + 1 - - - (a) \\ y = 2x + 5 - - - (b) \\ (a) - (b) \\ y = 0 \\ x = 0 \\ no \: solution$

The measure of an interor angle of a regular polygon is given. Find the number of sides in the polygon.

EleoNora [17]

Let side be n

$\\ \sf\longmapsto 120n=(n-2)180$

$\\ \sf\longmapsto 120n=180n-360$

$\\ \sf\longmapsto -60n=-360$

$\\ \sf\longmapsto n=6$

$\\ \sf\longmapsto 160n=(n-2)180$

$\\ \sf\longmapsto 160n=180n-240$

$\\ \sf\longmapsto -20n=-240$

$\\ \sf\longmapsto n=12$

$\\ \sf\longmapsto 144n=(n-2)180$

$\\ \sf\longmapsto 144n=180n-360$

$\\ \sf\longmapsto -36n=-360$

$\\ \sf\longmapsto n=10$

Hey so im also looking for the first answer and the choices were “ is not “ and “ is “

dexar [7]

so the investigator found the skid marks were 75 feet long hmmm what speed will that be?

$s=\sqrt{30fd}~~ \begin{cases} f=\stackrel{friction}{factor}\\ d=\stackrel{skid}{feet}\\[-0.5em] \hrulefill\\ f=\stackrel{dry~day}{0.7}\\ d=75 \end{cases}\implies s=\sqrt{30(0.7)(75)}\implies s\approx 39.69~\frac{m}{h}$

nope, the analysis shows that Charlie was going faster than 35 m/h.

now, assuming Charlie was indeed going at 35 m/h, then his skid marks would have been

$s=\sqrt{30fd}~~ \begin{cases} f=\stackrel{friction}{factor}\\ d=\stackrel{skid}{feet}\\[-0.5em] \hrulefill\\ f=\stackrel{dry~day}{0.7}\\ s=35 \end{cases}\implies 35=\sqrt{30(0.7)d} \\\\\\ 35^2=30(0.7)d\implies \cfrac{35^2}{30(0.7)}=d\implies 58~ft\approx d$
