Answer:

-28x+55

Step-by-step explanation:

step 1. Substitute the -6 into the 5x-8.

(2x+7)-6(5x-8)

2x+7-30x+48

step 2. Combine like terms.

2x+7-30x+48

<u>-28x+55</u>

Now, these are the simple steps you can follow.

Answer:

-28x-41

Step-by-step explanation:

6*5x-6*8

30x-48

2x+7-30x-48 = 2x-30x+7-48 = -28x+7-48 = -28x+(-41)= -28x-41

According to the fundamental theorem of algebra, which polynomial function has exactly 6 roots? f (x) = 5 x superscript 4 baseli
MariettaO [177]

The polynomial with 6 roots is the one of degree 6, so the correct option is:

f(x) = 7x^6 + 3x^2 + 12

<h3>Which polynomial function has 6 roots?</h3>

You need to remember that if p(x) is a polynomial of degree N, then it has N roots (such that some of these N roots may be equal or not).

Then we just need to find the polynomial of degree 6. (Remember that the degree represents the maximum exponent of the polynomial).

In this case, the only one of degree 6 is:

f(x) = 7x^6 + 3x^2 + 12

Which is the last option.

If (x)=3x-1 and s(x)=2x+1, which expression is equivalent to r over s (6) ?
katrin [286]

Answer:

\large\boxed{\dfrac{3(6)-1}{2(6)+1}}

Step-by-step explanation:

\left(\dfrac{f}{g}\right)(x)=\dfrac{f(x)}{g(x)}\\\\\text{We have}\\\\f(x)=3x-1,\ g(x)=2x+1\\\\\left(\dfrac{f}{g}\right)(x)=\dfrac{3x-1}{2x+1}\\\\\left(\dfrac{f}{g}\right)(6)\to\text{put x = 6 to the equation of the function}\ \left(\dfrac{f}{g}\right)(x):\\\\\left(\dfrac{f}{g}\right)(6)=\dfrac{3(6)-1}{2(6)+1}
