what positive number satisfies the condition that twice the number minus three times the reciprocal of the number is equal to 1?
marshall27 [118]
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>

Respuesta de (-0.5)²
Vladimir79 [104]

Answer:

0.25

Step-by-step explanation:

we have

(-0.5)^2

we know that

-0.5=-\frac{1}{2}

substitute

(-\frac{1}{2})^2=(-\frac{1}{2})(-\frac{1}{2})

Remember that

(-1)(-1)=1\\(-1)(1)=(-1)

so

(-\frac{1}{2})(-\frac{1}{2})=\frac{1}{4}=0.25

aliya0001 [1]
30% is 3/10. 260 times 3/10 is 780/10, or 78. She read 78 pages. 260 - 78 is 182 pages left.
