Answer:
(4,-4)
Step-by-step explanation:
Answer:
if the discriminant < 0 no solution
if = 0 then one solution
if > 0 then two solutions
start from the first one and calculate b^2-4ac
the first one is x^2 + 4x +4 = 0
a is the factor next to x^2 (1 in this case)
b is the factor next to x (4 in this case)
c is the number without any x (4 in this case)
so the discriminant is 4^2 - 4*(1)*4 = 16-16 = 0 = one solution
Step-by-step explanation:
The given statement " If a ray divides an angle into two complementary angles, then the original angle is not a right angle" is false.
As, Complementary angles are those in which sum of two angles add up to 90 degrees.
Now, let us consider two angles made by the ray is 'x' and 'y'. According to the question, the ray divides an angle into two complementary angles which means
In this case since the two angles formed after being divided by ray are complementary it means they add up to 90 degrees. And hence, the original angle should be a right angle.
Therefore, it is false to say that the original angle is not a right angle.
Answer:
Step-by-step explanation:
4(2x-1)=3x+5-x
8x-4=3x+5-x
8x-4=2x+5
6x-4=5
6x=9
x=3/2
