The easiest way to solve this problem is by using the Pythagorean theorem :D
Pythagorean theorem: [-b +- sqrt(b^2 - 4ac)]/2a
5 = a
-1 = b
6 = c
therefore, by plugging these values in!
[-(-1) +- sqrt((-1)^2 - 4(5)(6))]/2(5)
[1 +- sqrt(1 - 120)]/10
Oh so we're using imaginary numbers, so in this case you'll need to know that i = sqrt(-1), so keep this in mind (I can see why this was so difficult)
[1 +- sqrt(119)*i]10
answers:
( 1 + i*sqrt(119) ) / 10
( 1 - i*sqrt(119) ) / 10
-12x - 24 = -18x + 24
+24. +24
-12x = -18x + 48
+18x. +18x
6x = 48
/6. /6
X = 8
Adam is incorrect because if you substitute the value of y (which is 2) on the expression 52-3y=20, the statement is false since 46 is obviously not equal to 20.
52-3(2)=20
52-6=20
46 = 20
FALSE
Answer:
Q
Step-by-step explanation:
X has constant value
x'-x = 0
m =(y'-y)/(x'-x) --> undefined
I believe it would be D. If d=7 then the equation would be 2x7 which would equal 14
