Given the following equation:
We will find the real solutions to the equation by graphing.
We will rewrite the given equation as follows:
The graph of the function will be as shown in the following figure:
As shown the function has 3 real solutions which are the x-intercepts
So, the answer will be:
Answer: x = 1.5
Step-by-step explanation:
Subtract 3 from each side.
2x = 3
Divide both sides by 2
x = 1.5
Answer:
C
Step-by-step explanation:
the sum of the exterior angles of a polygon = 360°
sum the 4 exterior angles and equate to 360
8x + 9x + 5 + 5x + 4 + 9x + 3 = 360 , that is
31x + 12 = 360 ( subtract 12 from both sides )
31x = 148 ( divide both sides by 31 )
x ≈ 11.23 ( to 2 dec. places )
then exterior angle at B is
9x + 3 = 9(11.23) + 3 ≈ 104° → C
