Your friend claims that when a polynomial function has a leading coeffcient of 1 and the coefficients are all integers , every p

sammy [17]

Using the rational root theorem, it is found that your friend is correct.

<h3>What is the rational root theorem?</h3>

It is a theorem that states that for a polynomial with integer coefficients, with q being the factors of the leading coefficient and p being the factors of the constant, every possible rational root is the format $\frac{p}{q}$ .

In this problem:

The leading coefficient is 1, hence it's only factor is $q = 1$ , thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct.

Whats the lcd of 1/7,14/17,12/13,5/6

gizmo_the_mogwai [7]

LCD (1/7, 14/7, 12/13, 5/6)

LCM = (7, 7, 13, 6)

= 2 * 3 * 7 * 13

= 546

1/7 = 78/546

14/7 = 1092/546

12/13 = 504/546

5/6 = 455/546

Calculation:

1/7 + 14/7

= 1 + 14/7

= 15/7

The common denominator you can calculate as the least common multiple of the both denominators: LCM (7, 7) = 7

Add:

15/7 + 12/13

= 15 . 13/7. 13 + 12 . 7/13 . 7

= 195/91 + 84/91

= 195 + 84/91

= 279/91

The common denominator you can calculate as the least common multiple of the both denominators: LCM (7, 13) = 91

Add:

279/91 + 5/6

= 279 . 6/91 . 6 + 5 . 91/6. 91

= 1674/546 + 455/546

= 1674 + 455/546

= 2129/546

The common denominator you can calculate as the least common multiple of the both denominators: LCM (91, 6) = 546

Hence, 546 is the LCM/LCD of (1/7, 14/17, 13/13, 5/6).

Hope that helps!!!!!!

Y - 8 = -10 How do I verify the solution ?

prisoha [69]

Answer:

y = -2

Step-by-step explanation:

SOLUTION :-

Solve the equation.

Add 8 to both sides in order to isolate the equation.

$=> y - 8 + 8 = -10 + 8$

$=> y = -2$

∴ y = -2

VERIFICATION :-

To verify the solution of y , just put the solution (y = -2) in place of y in equation and check whether L.H.S = R.H.S.

L.H.S :-

-2 - 8 = -10

R.H.S. :-

-10 (already given)

⇒L.H.S. = R.H.S. (verified)
