What polynomial should be subtracted from the polynomial y2–5y+1 to get the difference equal to 5

VMariaS [17]

Answer: The polynomial

= y² - 5y - 4.

Step-by-step explanation:

Let the polynomial = f(y)

Therefore

y² -5y + 1 - f(y) = 5

f(y) = y² - 5y + 1 - 5

f(y) = y² - 5y - 4

The polynomial = y² - 5y - 4.

Check:

y² - 5y + 1 - ( y² - 5y - 4)

Open the bracket with the minus

y² - 5y + 1 - y² + 5y + 4

y² - y² - 5y + 5y + 1 + 4

= 0 - 0 + 5

= 5.

How many solutions does 2(b+3)-17=3b-7+b<br><br><br><br> I really need help thanks!

Ymorist [56]

Answer:

One solution

Step-by-step explanation:

Group like terms: $2\left(b+3\right)-17=3b+b-7$

$\mathrm{Add\:similar\:elements}\:3b+b=4b$ : $2\left(b+3\right)-17=4b-7$

Simplify: $2b-11=4b-7$

Add 11 to both sides

Simplify: 2b=4b+4

Subtract 4b from both sides

Simplify: -2b=4

Divide

And finally, you get -2
