Answer:
The roots of the equation are x =
and x = 
and there are no real roots of the equation given above
Step-by-step explanation:
To solve:
5x² − 3x + 17 = 9
or
⇒ 5x² − 3x + 17 - 9 = 0
or
⇒ 5x² − 3x + 8 = 0
Now,
the roots of the equation in the form ax² + bx + c = 0 is given as:
x = 
in the above given equation
a = 5
b = -3
c = 8
therefore,
x = 
or
x = 
or
x =
and x = 
or
x =
and x = 
here i = √(-1)
Hence,
The roots of the equation are x =
and x = 
and there are no real roots of the equation given above
Answer:
C. 4
Step-by-step explanation:
Since this one is already graphed and we can see it clearely we can just count, but you can also do change in y over change in x (aka "rise over run") to find the slope.
So, we count and find it is four up and one over. 4/1 = 4 = c
Hope this helps, have a nice day! :)
Answer:
Value of x is 20.
Step-by-step explanation:
The angle opposite to 4x is also 4x.
Similarly, the angle opposite to 5x is also 5x.
So, 4x+4x+5x+5x=360
18x=360
x=360/18
x=20
