Examine the following piecewise function.
miss Akunina [59]

By analyzing when the piecewise function increases and when it decreases, we can conclude that the true statement is:

"The function is increasing over the interval −8≤x≤−2."

<h3>Which statements are true?</h3>

We know that our function is made of straight lines that connect:

  • Point (-8, 3) with (-2, 8)   {This is an increasing line}
  • Point (-2, 8) with (2, 8)   {This is a horizontal line}
  • Point (3, 0), and (7, -7)   {This is a decreasing line}

(to see if it increases or decreases, compare the y-value of the second and first point. If the second is larger, then the line increases).

Then the statement that is true is:

3) "The function is increasing over the interval −8≤x≤−2."

The division algorithm states that if​ p(x) and​ d(x) are polynomial functions with d left parenthesis x right parenthesis not e
katrin [286]

Answer:

In a division algorithm, p(x) refers to the dividend polynomial, d(x) refers to the divisor polynomial, q(x) refers to the quotient polynomial and r(x) refers to the residula polynomial.

The division algorithm is defined as

p(x)=d(x) \times q(x) +r(x)

Where p(x)\geq d(x) and d(x) \neq 0, other wise the algorithm won't be defined.

So, the complete paragraph is: "if p(x) and d(x) are polynomial functions with d(x)\neq 0 and the degree of d(x) is less than or equal to the degree of p(x), then there exist unique polynomial functions q(x) and r(x) such that  p(x)=d(x) \times q(x) +r(x).

Answer:  \bold{w=\dfrac{6y-3}{2}}

<u>Step-by-step explanation:</u>

Isolate w by performing the following steps

  • Multiply by 6 on both sides to clear the denominator
  • Subtract 3 from both sides
  • Divide both sides by 2

y=\dfrac{1}{2}+\dfrac{w}{3}\\\\\\6\bigg[y=\dfrac{1}{2}+\dfrac{w}{3}\bigg]\quad \implies \quad 6y=3+2w\\\\\\6y-3=3-3+2w\quad \implies \quad 6y-3=2w\\\\\\\dfrac{6y-3}{2}=\dfrac{2w}{2}\quad \implies \quad \large\boxed{\dfrac{6y-3}{2}=w}
