Definitely Graph C.
The dots are aligned correctly to the line better than the other graphs.
Answer: x = - 2√5, √5/3
Step-by-step explantion
3 √ 5 x 2 + 25 x − 10 √ 5 = 0 35x2+25x−105=0
⇒ 3√5x2 + 30x – 5x – 10√5 = 0
⇒ 3√5x(x + 2√5) – 5(x + 2√5) = 0
⇒ (x + 2√5)(3√5x – 5) = 0
x = - 2√5, √5/3
Let smaller number be x/2 and the larger number x.
x/2 + x = 81
x/2 + x = 3x/2
3x/2 = 81
3x = 162
x= 54
The smaller number is 54/2= 27 and the larger number is 54.
Answer:
The angle is 28.
Step-by-step explanation:
If we consider the system below (were "A"is the angle):
A + [(x/2)-14] = 90 (complement)
A + x = 180 (suplement)
We can isolate "X=180 - A" and apply this in the first equation. This way we are able to have only one variable, and w'll see that A=28.
So, m is greater than -6. This means its either the third or fourth solution. Since the solution doesn't include -6, it would be the fourth option as the dot is hallow, which represents that the solution goes down to but does not include -6.
