Solve:
"<span>twice the number minus three times the reciprocal of the number is equal to 1."
3(1)
Let the number be n. Then 2n - ------- = 1
n
Mult all 3 terms by n to elim. the fractions:
2n^2 - 3 = n. Rearranging this, we get 2n^2 - n - 3 = 0.
We need to find the roots (zeros or solutions) of this quadratic equation.
Here a=2, b= -1 and c= -3. Let's find the discriminant b^2-4ac first:
disc. = (-1)^2 - 4(2)(-3) = 1 + 24 = 25.
That's good, because 25 is a perfect square.
-(-1) plus or minus 5 1 plus or minus 5
Then x = ------------------------------ = --------------------------
2(2) 4
x could be 6/4 = 3/2, or -5/4.
You must check both answers in the original equation. If the equation is true for one or the other or for both, then you have found one or more solutions.</span>
Answer:
0.000001
Step-by-step explanation:
It is because 10 is represented as just like 10 and then in a certain place. And then the negative means it is to the right of the decimal. 6th power means the 6th place. So, basically it means, 10 in the 6th to the right place which is 0.0000010. You do not need the last zero because there is no value after that, so 0.000001.

Answer:
16/15
Step-by-step explanation:
The two minus signs cancel, so the result is positive.
Answer:x5
Step-by-step explanation:Let's solve your equation step-by-step.
4x+2=2x+12
Step 1: Subtract 2x from both sides.
4x+2−2x=2x+12−2x
2x+2=12
Step 2: Subtract 2 from both sides.
2x+2−2=12−2
2x=10
Step 3: Divide both sides by 2.
2x
2
=
10
2
x=5
