Solve for v . =−16 − 47v
Schach [20]
I'm pretty sure this is what you have to do;
v=-16-47v
add 47v on the other side of the equal sign
47v=-16
then divide 47 on each side of the equal sign
47v÷47v=1v or just v
-16÷47=-0.3
v=-0.3
I think this is right.
Hope this helps

Answer:

The polynomial is x^{4}-4x^{3}+3x^{2}

Step-by-step explanation:

∵ The polynomial of dgree 4 has 3 , 1 and zero as a double root

∴ x = 3 , x = 1 , x = 0 , x = 0

∴ The factors of this polynomials are:

   (x - 3) , (x - 1) , (x) , (x)

∴The polynomial = (x)(x)(x - 3) (x - 1)

∴ The polynomial = x^{2}(x^{2}-4x+3)=x^{4}-4x^{3}+3x^{2}

The sum of the digits of a two digit number is 8.if the ten digit is 4 more than the units digit what is the number
PIT_PIT [208]

Answer:

The number is 62.

Step-by-step explanation:

If the number is xy then x + y = 8.

Also x - y = 4.

x + y = 8

Adding the above 2 equations eliminates y:

2x = 12

x = 6

and y = 8-6 = 2.
