In triangle ABC,
we know that,
exterior angle C = angle B + angle A
=> 3x - 2 = x + 4 + 82
=> 3x-x = 82 + 4 + 2
=> 2x = 88
=> x = 88/2
=> x = 44
Answer:
C
Step-by-step explanation:
slope is the change of y / change of x
.
we can pick any points and find the changes in y and x
lets pick (0 , 0) and (5 , 6) .
the change of y = 6-0 = 6.
the change of x = 5-0 = 5.
so the slope of the line is 6/5
.
Answer:
yes
Step-by-step explanation:
just sub in the 4 for the w and see if the equation can be solved. if it can, then w=4 is a solution.
since 4 IS less than 11 5, w=4 can be a solution.
Brainliest please!!! Have a good day!!!!
Hello from MrBillDoesMath!
Answer:
(y+ 5/6)^2 = 169/36
Discussion:
3y^2+5y=12 => (divide both sides by 3)
y^2 + (5/3)y = 12/3 = 4 =>
Add\subtract the square of one-half the coefficient of y:
( y^2 + (5/3)y + (5/6)^2) - (5/6)^2 =4 (add (5/6)^2 to both sides)
(y^2 + (5/3)y + (5/6)^2 = 4 + (5/6)^2 =>
(y+ 5/6)^2 = 4 + (5/6)^2 = 4 + (25/36) =
(144+25)/36 = 169/36
So
(y+ 5/6)^2 = 169/36
We can also solve for y by taking the square root of both sides:
(y + 5/6) = sqrt(169/36)
= +\- 13/6 ( as 169 = 13*13 and 36 = 6*6)
y = (-5/6) +\- 13/6
Thank you,
