What is the discriminant of the polynomial 4x^2 - 20 x + 25 ?
Zarrin [17]

Hello from MrBillDoesMath!

Answer:

0

Discussion:

For the quadratic ax^2 + b^x + c, the discriminant is b^2 - 4ac. In our case, the discriminant is

(-20)^2 - 4 (4)(25) =

400      - 4 (100)   =

0

(This means the polynomial has a duplicate root. In fact it factors as          (2x-5)^2       ).


Thank you,

MrB

Tommy has 6 more than 3 times the amount of money in his bank account than Judy. Judy has $7500 more than a number in her accoun
Ad libitum [116K]

Answer:

Amount of money Judy has in her account is \$(7500+n).

Amount of money Tommy has in his account is  \$(22506+3n)

Step-by-step explanation:

To find : Amount of money in Judy account and amount of money in Tommy account:

Solution:

Given:

Judy has $7500 more than a number in her account.

Let the number be 'n'.

So we can say that;

Amount of money in Judy account is equal to 7500 plus number.

framing in equation form we get;

Amount of money in Judy account = \$(7500+n)

Hence Amount of money Judy has in her account is \$(7500+n).

Now Given:

Tommy has 6 more than 3 times the amount of money in his bank account than Judy.

So we can say that;

Amount of money in Tommy account is equal to 3 multiplied by Amount of money in Judy account plus 6.

framing in equation form we get;

Amount of money in Tommy account = 3(7500+n)+6 =22500+3n+6=\$(22506+3n)

Hence Amount of money Tommy has in his account is  \$(22506+3n).
