Y = 1x + 2
-2y = 1x
-2y = x

^^^ I believe that is correct

Use the quadratic formula to find both solutions to the quadratic equation given below 3x^2-x+5=0

lora16 [44]

For this case we have the following quadratic equation:

$3x ^ 2-x + 5 = 0$

We have to:

$a = 3\\b = -1\\c = 5$

The quadratic equation states that:

$x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

Substituting the values we have:

$x = \frac {- (- 1) \pm \sqrt {(- 1) ^ 2-4 (3) (5)}} {2 (3)}\\x = \frac {1 \pm \sqrt {1-60}} {6}\\x = \frac {1 \pm \sqrt {-59}} {6}\\x = \frac {1 \pm \sqrt {59i ^ 2}} {6}\\x = \frac {1 \pm i \sqrt {59}} {6}$

We have two roots:

$x_ {1} = \frac {1 + i \sqrt {59}} {6}\\x_ {2} = \frac {1-i \sqrt {59}} {6}$

Answer:

$x_ {1} = \frac {1 + i \sqrt {59}} {6}\\x_ {2} = \frac {1-i \sqrt {59}} {6}$

Someone plz help ill really appreciate it

julia-pushkina [17]

I believe it is A because you add all of the numbers together and get 47. Then you divide by the numbers that appear often. In this case it is 2. Divide 47 by 2 and you get about 22 or 23.

Hope this helps and is correct :)

Part E: Very small numbers are often written in exponential form using scientific notation to make them easier to multiply or di

Alex777 [14]

<span>When multiplying numbers written in scientific notation you can take the numbers without the 10^exponent part and multiply them and then add the exponents of the base 10 powers. For example (A*10^B) * (C*10^D) is the same as (A*C)*10^(B+D). For dividing it works the same way, only instead of adding the exponent you subtract them. For example (A*10^B) / (C*10^D) is the same as (A/C)*10^(B-D).</span>
