40x=10x^2+41 Identify the number of solutions and their types using the discriminant

Mathematics

nydimaria [60]3 years ago

Number of solutions: no roots

Type of solution: Not Real

Step-by-step explanation:

We need to identify the number of solutions and their types using the discriminant.

We are given: 40x=10x^2+41\\

Rearranging:

40x-10x^2-41=0\\10x^2-40x+41=0

Discriminant can be found by: b^2-4ac

where b=-40, a=10 and c=41

Putting values:

b^2-4ac\\=(-40)^2-4(10)(41)\\=1600-1640\\=-40\\

So, Discriminant is -40

If the discriminant is less than zero i.e -40 then there are no real roots.

So, Number of solutions: no roots

Type of solution: Not Real

Keywords: discriminant

Elena has 2 fewer hats then fran. Together, they have 14 hats. Which equation represents this situation.
Free_Kalibri [48]
<h2>Greetings!</h2>

Answer:

2x - 2 = 14

Step-by-step explanation:

Let x be the amount of hats Fran has, if Elena has -2 hats, then this can be shown by x - 2

So then

x + x - 2 = 14

2x - 2 = 14

You haven't asked this but to find the amount of hats they have, move the -2 over to the other side making it a +2:

2x = 14 + 2

2x = 16

x = 8

So Fran has 8 hats and Elena has 6 hats.


<h2>Hope this helps!</h2>

The conversion from yards to feet and feet to miles are given.

You need to convert seconds to hours.

The conversion already given for time has 1 minute as the denominator, so the next conversion fraction needs to have minutes as the numerator.

The answer would be: A)  60 min/ 1 hour

Which ordered pair makes the equation true? 2x – 8y = –4
aalyn [17]
There aer infinite numbers
to make it easier we can solve for y

2x-8y=-4
x-4y=-2
-4y=-x-2
y=(1/4)x+(1/2)
some values aer
x=0, y=1/2
x=-2, y=0
