What are the solutions to 0=x^2-x+1?

kumpel [21]

Answer: No solutions

Step-by-step explanation:

There are no solutions to 0 = x² - x + 1.

[Method One]

We can solve this by rewriting the equation, but it is quicker to graph it when there are no solutions. See attached.

[Method Two]

I said we can solve this by solving an equation, here it is. We will use the quadratic formula since the equation given is already in the proper form.

$\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

$\displaystyle x=\frac{1\pm\sqrt{(-1)^2-4(1)(1)} }{2(1)}$

$\displaystyle x=\frac{1\pm\sqrt{-3} }{2}$

-> Negative numbers don't have real square roots, so there is no solution

Translate the sentence into an equation, then solve the

Oduvanchick [21]

Answer:

The equation is: $\frac{x-7}{5} = 13$ and the number is 72.

Step-by-step explanation:

We have to use mathematical notation to convert the given statement into an equation. As we don't know the exact value of number, we have to use a variable in place of the number.

Let x be the required number then

"A number decreased by 7"

$x-7$

"and then divided by 5"

$\frac{x-7}{5}$

" is 13."

$\frac{x-7}{5} = 13$

For solving, multiplying both sides of equation by "5"

$\frac{x-7}{5} * 5 = 13*5\\x-7 = 65$

Adding 7 on both sides of equation

$x-7+7 = 65+7\\x = 72$

Hence,

The equation is: $\frac{x-7}{5} = 13$ and the number is 72.

it takes Joey 1/6 of an hour write one thank you card. how many cards can he write in 3/4 of an hour?

Sauron [17]

1/6 of an hour is equivalent to 10/60 or 10 minutes.
To find out how much 3/4 of an hour is, change the denominator of both fraction so that they match up. We can make this easier by multiplying 4 by 15 to get 60 (hence an hour) and since we multiplied 4 by 15, we also need to multiply 3 by 15 which gets us 45.
We end up with 10/60 and 45/60 or 10 minutes and 45 minutes.
Half of 10 is 5 so we know we'll have a decimal of .5 in our answer.
4 times 10 equals 40 and 40 plus 5 equals 45, so 4.5.
