Answer:

31°

Step-by-step explanation:

Angle KLN and Angle MLN equal 160° as said in the directions.

So 2y° + (3y + 5)° = 160° –– Combine like terms

5y + 5° = 160° ––Subtract 5 from both sides

5y° = 155° –– Divide both sides by 5 to get y alone

y = 31°

Find the equation of the line that has slope -5/6 and which passes through (-1,-6).

Sergeeva-Olga [200]

Just plug it into the formula

y-(-6)=-5/6(x-(-1))
y+6=-5/6(x+1)
y=-5/6(x)-5/6-6

The answer is: f(x)=-5/6(x)-41/6

Write the values in the boxes that make the statement true

nikklg [1K]

Answer:

$\frac{5}{3}xz^8*9x^6y^0z^2 = 15x^7z^{10}$

Step-by-step explanation:

Given

$\frac{5}{3}xz^a*bx^cy^dz^2 = 15x^7z^{10}$

Simplify

$\frac{5}{3}b*x^{1+c}z^{a+2}y^d = 15x^7z^{10}y^0$

Compare left and right sides and

Find b:

$\frac{5}{3}$ b = 15 ⇒ b = 15*3/5 = 9

Find c:

1 + c = 7 ⇒ c = 7 - 1 = 6

Find a:

a + 2 = 10 ⇒ a = 10 - 2 = 8

Find d:

d = 0

Solution is:

$\frac{5}{3}xz^8*9x^6y^0z^2 = 15x^7z^{10}$

Me ajudem com a 3º questão

Alisiya [41]

I can't read that language but I'll guess it says write a second degree equation then solve for n when d=10.

$10 = \dfrac{n(n-3)}{2}$

$20 = n^2 - 3n$

$n^2 - 3n - 20 = 0$

Answer: n² - 3n - 20 = 0

That doesn't factor so there is no integer n solution.

That means there are no polygons with 10 diagonals.

$n = \frac 1 2(3 \pm \sqrt{89})$
