Answer:

c. 6

Step-by-step explanation:

Given

See attachment for graph

Required

Average rate of change

This is calculated as:

Rate = \frac{f(b) - f(a)}{b - a}

Where

(a,b) = (2,4)

So, we have:

Rate = \frac{f(4) - f(2)}{4 - 2}

Rate = \frac{f(4) - f(2)}{2}

Using the attached graph, we have:

f(2) = 4

f(4) = 16

So, we have:

Rate = \frac{16- 4}{2}

Rate = \frac{12}{2}

Rate = 6

Name a value for x that will complete the inequality that is shown. Then, explain why the value makes the inequality true.

<h3>Answer:    0.157</h3>

========================================================

Explanation:

Convert the fraction 9/50 to decimal form. You can use either long division or a calculator.

You should find that 9/50 = 0.18 which is the same as 0.180

So the original compound inequality is the same as saying 0.125 < x < 0.180

This tells us that x is between 0.125 and 0.180 where x is not equal to either endpoint. We simply need to pick anything in this interval. It can be anything you want (I recommend to use a number line to help pick a value). One such value is 0.157. There are infinitely many values you can select from.

The number 0.157 is between 0.125 and 0.180, ie  0.125 < 0.157 < 0.180

It's very similar to saying 157 is between 125 and 180, ie 125 < 157 < 180.

Please help me. I don't know how to find the slope of this graph.
choli [55]

Answer:

3/4

Step-by-step explanation:

We know this is a positive sloe because the line goes up from left to right.

We can pick to points  (0,1) and (4,4)

We can find the slope from

m = (y2-y1)/(x2-x1)

   = (4-1)/(4-0)

   =3/4

1.03x+ 3.97x-5=13 solve for x.
ziro4ka [17]

Answer:

X = \frac{18}{5}, or X = 3.6

Step-by-step explanation:

For this problem we must isolate x

1.03x+3.97x-5=13 | Add 5 to both sides

1.03x+3.97x=18 | Add the x's

5x=18 | Now divide both sides by 5

x=\frac{18}{5}, x=3.6

What is the value of the algebraic expression if x= 1/2 , y = -1, and z = 2? 6x(y2z) A. -12 B. -6 C. 1 D. 6
Free_Kalibri [48]
To determine the value of the given algebraic expression above, we simply substitute the values of each variable to the variables in the expression and evaluate the expression. We do as follows:

6x(y^2)(z)
      when x = 0.5
                y = -1
                z = 2
6(0.5)((-1)^2)(2)
3(1)(2)
6

The value of the algebraic expression would be 6. An algebraic expression consists of variables which are represented with letters like for this case x, y and z, a coefficient which is indicated by numbers (e.g. 6 ) and exponents like 2 for the expression above. Often times expressions contains a number of terms which consists of those elements.
