I WILL MARK BRAINLIEST!!! 45 POINTS!!!! <br> Solve using substitution<br> y= -8x-6<br> y= -3x +4

Nuetrik [128]

Given :

y= -8x-6

y= -3x +4

By solving it, we get,

-8x-6 = -3x+4

$= > x = - 2$

Substituting the value of "x" in second given equation,

$y = - 3x + 4$

$= > y = - 3 \times ( - 2) + 4$

By solving it, we get,

$y = 10$

Hence, the values are :-

$x = - 2 \\ y = 10$

If the measure of each exterior angle of a regular polygon is 18°, determine how many sides the polygon has.

Sveta_85 [38]

we are given

exterior angle is 18

so,

$\theta=18$

now, we can use formula

number of sides of regular polygon = 360/(exterior angle)

so, we get

$n=\frac{360}{18}$

$n=20$

so, number sides is 20..........Answer
