We know that the total is 180 degrees of the lines.
To find x:
(5x+20)+(4x-11) = 180
x=19
To find y, input the value of x into the equation 4x-11 since this equation is equal to 2y+19
4(19)-11 = 65
2y+19 = 65
y=23
G(-1) = 1 / -1 = -1
f(g(-1)) = (-1)^2 + 9(-1) = 1 - 9 = -8 Answer
f(1/2) = (1/2)^2 + 9(1/2) = 1/4 + 4 1/2 = 19/4
g((f(1//2)) = 1 / 19/4 = 4/19 Answer
Answer:
the correct answers are
What value is placed on top of the X? 90
What value is placed on the bottom of the X? 21
What is the factored form of 9x2 + 21x + 10? (3x + 2)(3x + 5)
