The Spotlight on Teaching and Learning at the beginning of this chapter discusses the emphasis in the Common Core State Standard

s for Mathematics on learning about measurement by measuring real objects. Look back at this page and respond to the first “Think About This” question by giving a specific description of an activity that would involve second-graders in learning to measure length and selecting an appropriate tool to use.

Answer: B

Step-by-step explanation:

(f/g) means to divide f(x) by g(x).

(f/g)(x)=\frac{3x+2}{3x-5}

To find the domain, you set the domain equal to zero and solve for x.

3x-5=0                   [add both sides by 5]

3x=5                       [divide both sides by 3]

x=5/3

Now, we know that B is the correct answer.

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:y >
pantera1 [17]

Answer:

Part A: The graph of given inequality is shown below.

Part B: The point (4,6) is not a solution of given system of inequalities.

Step-by-step explanation:

Part A:

The given inequalities are

y>2x+3

y

The related equation of given inequalities are

y=2x+3

y=-\frac{3}{2}x-4

Put x=0, to find the y-intercepts.

y=2(0)+3=3

y=-\frac{3}{2}(0)-4=-4

Put y=0, to find the x-intercepts.

0=2x+3\Rightarrow x=-\frac{3}{2}

0=-\frac{3}{2}x-4\Rightarrow x=-\frac{8}{3}

The x and y-intercepts of first line are (0,3) and (-1.5,0) respectively. The x and y-intercepts of second line are (0,-4) and (-2.667,0) respectively.

Check the given inequality by (0,0).

0>2(0)+3

0>3

This statement is false. It means (0,0) is not the solution of this inequality and the shaded region is opposite side of the origin.

0

0

This statement is false. It means (0,0) is not the solution of this inequality and the shaded region is opposite side of the origin.

The graph of given inequalities is shown below.

Part B:

We have to check whether (4,6) is a solution of the system of inequality or not.

Check the given inequality for the point (4,6).

(6)>2(4)+3

6>11

This statement is false. It means (4,6) is not the solution of given system of inequalities.
