-138≥-6(6b-7)║ what is the value of b?

1 answer:

7 0

-138 ≥ -6(6b - 7)

Start by multiplying everything within the parentheses by -6.

-138 ≥ -36b + 42

Now move the +42 to the other side, so you're left with -36b. (You do this by subtracting 4242)

-138 - 42 ≥ -36b

-180 ≥ -36b

Divide both sides by -36 to find the value of b.

-180 / -36 ≥ b

5 ≥ b.

The answer is b ≤ 5.

Which polynomial equation of least degree has -2, -2, 3, and 3 as four of its roots? (x + 2)(x - 3) = 0 (x - 2)-2(x + 3)3 = 0 (x

azamat

Answer:

(x + 2)²(x - 3)² = 0

Step-by-step explanation:

Since we have a degree of 2 and double of the same roots, we know that each root would have a multiplicity of 2. Therefore, our answer is(x + 2)²(x - 3)² = 0
