What is the solution for 5x^2-x+6=0

Mathematics
1 answer:
kati45 [8]3 years ago

The easiest way to solve this problem is by using the Pythagorean theorem :D

Pythagorean theorem: [-b +- sqrt(b^2 - 4ac)]/2a

5 = a

-1 = b

6 = c

therefore, by plugging these values in!

[-(-1) +- sqrt((-1)^2 - 4(5)(6))]/2(5)

[1 +- sqrt(1 - 120)]/10

Oh so we're using imaginary numbers, so in this case you'll need to know that i = sqrt(-1), so keep this in mind (I can see why this was so difficult)

[1 +- sqrt(119)*i]10

answers:

( 1 + i*sqrt(119) ) / 10

( 1 - i*sqrt(119) ) / 10

Jason is buying 2 hats and 3 scarves for each of his 4 children

so he is actually buying 8 hats and 12 scarves.

a hat costs 8.50 and a scarf costs 5.50

so you put it into a equation

8.50(h)+5.50(s) = P     h = hat, s = scarf, P = pay

8.50(8)+5.50(12) = P

68 + 66 = P

P = 134

hope this helps

Jim had 360 stamps he sold 1/3 of them on Monday and 1/4 of the remainder on Tuesday how many stamps did he sell on Tuesday
denis-greek [22]

Answer:

60

Step-by-step explanation:

Since Jim sold 1/3 of his stamps on Monday, the remainder would be 2/3 of his total stamps.

<em>Divide 360 stamps by 3. Minus the stamps</em><em> </em><em>sold on Monday from 36</em><em>0</em><em> </em><em>to</em><em> </em><em>get</em><em> </em><em>the</em><em> </em><em>remainder</em><em>.</em>

stamps sold on Monday = 360 ÷ 3 = 120

remainder = 360 - 120 = 240

He sold 1/4 of the remainder on Tuesday.

<em>Divide the remainder by 4.</em>

stamps sold on Tuesday = 240 ÷ 4 = 60

<em>He sold 60 stamps on Tuesday</em><em>.</em>
