Solve y-4=3x+5y for y
Inga [223]
<h3><u>The value of y is equal to (-4 - 3x)/4.</u></h3>

Because there are two variables and only one equation, we cannot solve for the exact value of y.

However, we can still get a value of y.

y - 4 = 3x + 5y

Subtract y from both sides.

-4 = 3x + 4y

Subtract 3x from both sides.

-4 - 3x = 4y

Divide all terms by 4.

(-4 - 3x)/4 = y

Which second degree polynomial function has a leading coefficient of –1 and root 4 with multiplicity 2?
Fynjy0 [20]

Answer:

-(x-4)^{2}

or -x^{2}+8x-16

Step-by-step explanation:

Given a second degree polynomial has a root 4 with multiplicity 2

That means, 4 is a repeating root of the polynomial.

Any second degree polynomial has at most 2 real roots.

⇒Both roots of the polynomial are 4.

and its expression can be written as c·(x-4)^{2} where c is a real number

⇒c·(x^{2}-8x+16)

⇒cx^{2}-8cx+16c

Also, the leading coefficient is given as -1

So, c = -1

and the expression becomes (-1)x^{2}-8·(-1)·x+16·(-1)

⇒<u>-x^{2}+8x-16</u>
