The probability is 1/4 because there are 20 numbers (?/20) and 5 are divisible by four (-4,-8,-12,-16,-20) which makes 5/20 which simplified = 1/4.
Answer:
(0,-3)
Step-by-step explanation:
left 2 puts you at (0,3) and flipping over x axis makes the y value negative, so it's (0,-3)
1. Slope = Yb - Ya / Xb - Xa
= 7-3/2-(-2)
= 7-3/2+2
= 4/4
= 1
2. Y-intercept
Y = mx + b
7 = (1)(2) + b
7 = 2 + b
7 - 2 = 2-2 + b (two’s cancel out and we are just left with our b on the right side)
5 = B
Therefore, the equation is: Y = 1x + 5 which is also the same thing as: Y= X +5.
L+R=19
L-R=9
2L=28
L=14
(14)+R=19
R=5
L=14
R=5
Check:
(14)+(5)=19
(14)-(5)=9
Answer:
101°
Step-by-step explanation:
The interior angles indicated add up to the exterior angle <KMN because they are on the opposite side of it. You can substitute these into an equation to find x.
4x + 81 = 13x + 36
Group like terms
4x - 13x = 36 - 81
-9x = -45
Divide both sides of the equation by -9 so x can stand alone
![\frac{-9x}{-9} = \frac{-45}{-9}](https://tex.z-dn.net/?f=%5Cfrac%7B-9x%7D%7B-9%7D%20%3D%20%5Cfrac%7B-45%7D%7B-9%7D)
x = 5
Now to find <KMN, we just have to substitute 5 into the expression
= 13(5) + 36
= 65 + 36
= 101°
