How many roots does the equation 3x² = 1 - 7x have and what is the nature of the roots

Mathematics
1 answer:
AnnyKZ [126]3 years ago
7 0

Answer:

Step-by-step explanation:

Rewrite this quadratic in standard form:  3x^2 + 7x - 1.

The coefficients of x are {3, 7, -1}, and so the discriminant is b^2 - 4ac, or

7^2 - 4(3)(-1), or 49 + 12, or 61.  Because the discriminant is positive, this quadratic has two real, unequal roots

What happens when demand exceeds supply?
marta [7]

Answer:  Option 'b' is correct.

Step-by-step explanation:

Since we have that

When Demand exceeds supply.

It means money supply is more in the country due to which demand for a good increased more than supply.

It is the situation of inflation.

In this case, price would increase to curb the increase in demand.

For example, if the prevaling price for a particular good is $5, so a person is willing to purchase 10 units as he has $50.

But if the price gets increased and the new price becomes $10, then that person can buy only 5 units from $50.

So, it can reduce the demand and makes it equal to supply.

So, Option 'b' is correct.

Imma need sum help please
MrRa [10]

Answer:

Step 5

Step-by-step explanation:

The mistake is in step 5.

The previous step was

step \: 4 : 2 + 10 \div 2

The order operations, PEDMAS, must be applied:

We have Addition and Division here,

Using PEDMAS, we must divide first to get:

step \: 5 : 2 + 5

We can now add to get:

step \: 6: 7

Therefore the mistake occurred at step 5
