Answer:
C
Step-by-step explanation:
The number of roots of a quadratic function can be determined from its discriminant.
If Disc> 0, the function has two distinct roots
If Disc = 0, the function has a repeated root
If Disc < 0, the function has no real root.
The discriminant can be calculated as:
Disc = b² - 4ac
For the given equation:
Disc = 9 - 4(2)(1) =1
Since the value of discriminant is positive, the function will have two distinct roots.
So, the answer to this question is option B
Answer:
x= 110
Step-by-step explanation:
Supplementary angles add to 180
Let x be the other angle
x +70 =180
Subtract 70 from each side
x+70-70=180-70
x = 110
