Answer:
A) y = x^2 -1
B) -y = 2x^2 +1 We multiply B) by -1
B) y = -2x^2 -1
We can then say x^2 -1 = -2x^2 -1
3 x^2 = 0
x = 0
************* Double-Check: ******************
Equation A) y = -1 and
Equation B) y = -1

Answer:
426.07 square units
Step-by-step explanation:
Recall that for a triangle whose angles are A,B,C with corresponding sides a, b, c, the area G of the triangle may be computed as
G = 1/2 ab Sin C
or
G = 1/2 bc Sin A
or
G = 1/2 ac Sin B
Going by this, recall that the sum of angles in a triangle is 180 hence
94 + 26 + K = 180
120 + K = 180
Subtract 120 from both sides
K = 180 - 120
K = 60 degrees
Given that JK = 24 and JL = 41
G = 1/2 * 24 * 41 Sin 60
= 426.07 square units
Hello from MrBillDoesMath!
Answer:
60
Discussion:
As JG bisects FJG,
FJG = GJH =>
2x + 4 = 3x-9 => subtract 2x from each side
4 = 3x -2x - 9 => simplify
4 = x - 9 => add 9 to both sides
4 + 9 = x
x = 13
Now, FJH =
FJG + GJH
(2x + 4) + (3x-9) =
5x -5 => substitute x 13
5(13) -5 =
65 - 5 =
60
