<h3>Given :</h3>

  • z = - 2

<h3>To Find :</h3>

  • 3 - 6(z - 2) = ?

<h3>Solution :</h3>

By substituting value of z = - 2 in 3 - 6(z - 2), we get :

\tt : \implies 3 - 6(z - 2) = 3 - 6((-2) - 2)

\tt : \implies 3 - 6(z - 2) = 3 - 6(-2 - 2)

\tt : \implies 3 - 6(z - 2) = 3 - 6(- 4)

\tt : \implies 3 - 6(z - 2) = 3 + 24

\tt : \implies 3 - 6(z - 2) = 27

\large \underline{\boxed{\bf{ 3 - 6(z - 2) = 27}}}

Hence, value of 3 - 6(z - 2) = 27.

Mai and Tyler work on the equation 2/5b+1=-11 together. Mais soulution is b=-25 and Tyler’s is b=-28. Here is their work. Do you
Anika [276]

Answer:

No I don't agree with their solution; both their answers are wrong.

Correct answer is b=-30.

Step-by-step explanation:

Given:

\frac{2}{5}b+1=-11

Now given:

According to Mai b = -25 and According to Tyler b = -28

Now we need to find which of them is correct.

So we will solve the given equation we get;

\frac{2}{5}b+1=-11

Subtracting both side by 1 we get;

\frac{2}{5}b+1-1=-11-1\\\\\frac{2}{5}b =-12

Now Multiplying both side \frac{5}{2} we get;

\frac{2}{5}b\times\frac{5}{2}= -12 \times \frac{5}{2}\\\\b=-6\times 5\\\\b=-30

Hence both of them are incorrect, correct answer is b=-30.

The rate of change for the interval between 2 and 6 on the x-axis is 3.

Given

On a coordinate plane, a parabola opens up.

Solid circles appear on the parabola at (negative 4, 14), (negative 3, 9. 5), (negative 2, 6), (0, 2), (1, 1. 5), (2, 2), (4, 6), (5, 9. 5), (6, 14).

<h3>What is the rate of change?</h3>

A rate of change defines how one quantity changes in relation to another quantity.

The rate of change for the interval between 2 and 6 on the x-axis is;

\rm Rate \ of \ change =\dfrac{2-14}{2-6}\\\\Rate \ of \ change =\dfrac{-12}{-4}\\\\Rate \ of \ change =3

Hence, the rate of change for the interval between 2 and 6 on the x-axis is 3.
