Is (x-1) a factor of 2x3 - 15x2 + 22x + 15
Advocard [28]

Answer:

Step-by-step explanation:

If x - 1 is a factor of the cubic, then 1 should result in 0 when you put it in the cubic for x. Does it?

f(1) = 2(1)^3 - 15(1)^2 + 22(1) + 15

f(1) = 2 - 15 + 22 + 15

f(1)= 24.

No the result is not zero. So x - 1 is not a factor.

However there must be something that makes this cubic go to zero. The easiest way to find it is to graph it.

The numbers that do make this zero are -0.5, 3, 5

Which mean that the factors are (2x+1)(x-3)(x - 5)

Let
s-------> <span>represent the number of sheep
g-------> </span><span>represent the number of goats

we know that
1) </span><span>Morgan moves no more than 26 of her sheep and goats into another field
so
(s+g) </span><span>≤ 26------> inequality 1

2) </span><span>Fewer than 14 of her animals are sheep
so
s < 14-------> inequality 2

therefore

the answers are
</span><span>B.) s < 14 
</span><span>D.) s + g ≤ 26</span>
