2Tvwo §9.6 Mixed exercises

First we'll do task 41 together.

All take your Notebook and a pen, please!

Think about HOW to SOLVE question 41a.

Your teacher will ask one of you to respond.

Make 41 a in your Notebook, now.

SOLUTION 41a:  

Make 41 b in your Notebook, now.

Solution 41b:  

Make 41c in your Notebook, now.

Solution 41c:

Think about 41d now:

what information do we use, to make the formula for line m?

Your teacher will ask one of you to respond.

More information - next slide!

We need the coordinates of these points:

C (-2, 0) and point (0, 3).

With this we calculate the GRADIENT. The y-intercept we just read off.

Now make 41d in your Notebook.

Solution:   

Think about 41e.

What do do to find these coordinates?!

Your teacher will give someone a turn.

Make 41e now. 

Solution 41e:

Question: Where to find the METHOD to SOLVE these INEQUALITIES?

 The METHOD to SOLVE these INEQUALITIES 

we find on p.101/102.

Study and use this when doing task 42!

A TIP for 43a, PLOTTING the 3 GRAPHS:

Make 3 TABLES, containing (only) three points:

Take for example x = 0    x = 5    and    x = 10

The SOLUTIONSBOOK gives 3 x times 10 points!? 

A few too many, I guess...

For doing 45, choose (only) 6 equations to solve.

3 From the Left and 3 from the Right side.
