Answer: -5, -7, and -9

Step-by-step explanation:

checking the pattern they are subtracting by two by the next term, so subtracting 2 from -3 would be -5 and so on.

Explain how the Remainder Theorem and the Factor Theorem are related.

Daniel [21]

Basically the remainder theorem links the remainder of division by a binomial with the value of a function at a point while the factor theorem links the factors of polynomial to its zeros

If p(x) = x2 – 1 and q(x) = 5(x-1) which expression is equivalent to (p – q)(x)?

lilavasa [31]

Answer:

Option C is correct.

The expression which is equivalent to (p-q)(x) is, $x^2 -1 - 5(x-1)$

Step-by-step explanation:

Given: $p(x) = x^2 -1$ and q(x) = 5(x-1)

To find the expression which is equivalent to (p-q)(x):

here p and q both are function assuming;

we can write the expression :

(p-q)(x) = p(x) - q(x) = $x^2 -1 - 5(x-1)$

therefore, the expression which is equivalent to (p-q)(x) is; $x^2 -1 - 5(x-1)$

Write a linear function that passes through (1,5) and (2,15)

Leokris [45]

Simple,

using $\frac{y1-y2}{x1-x2} =m (slope)$

find your slope...

$\frac{5-15}{1-2} = \frac{-10}{-1}=10$

thus, 10=m (slope)

Now, using y=mx+b to find your equation, plug in what you know...

Use any of the 2 coordinates.. (1,5)

5= 10(1)+b

5=10+b
-10 -10

-5=b

Thus, the equation to your line is...

y=10x-5.
