Subtract 5 to both sides so that the equation becomes -2x^2 + 6x - 1 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -6 ± √((6)^2 - 4(-2)(-1)) ] / ( 2(-2) )
x = [-6 ± √(36 - (8) ) ] / ( -4 )
x = [-6 ± √(28) ] / (-4)
x = [-6 ± 2*sqrt(7) ] / (-4 )
x =3/2 ± -sqrt(7)/ 2
The answers are 3/2 + sqrt(7)/2 and 3/2 - sqrt(7)/2.
Answer:
A. They make the same amount
Step-by-step explanation:
You can use the cross multiplication method to find the answer:
$ hrs
200 × 10
300 15
200 × 15 = 3000
300 × 10 = 3000
The answer is 5^7 because you add the exponents
Answer:
Your answer is 40%
Step-by-step explanation:
It is 20 units between Z and B.
We add 2 more points, and one of them is at the the halfway point of the entire line.(M)
One of them is only 2 units away from B.(N)
That means our line is halved, so from 20/20 possible places a point could go and land in the right area is now 10/20.
Minus 2 from that; to take into count of the N to B, and you have 8/20
8/20 is just 40%
