When dividing fractions the second term becomes the reciprocal

9514 1404 393

**Answer:**

- no
- no

**Step-by-step explanation:**

If the graph is not a straight line, it is not a linear function. Neither graph 1 nor graph 2 is a straight line, so **neither is a linear function**.

__

Graph 2 is made of parts of two straight lines. It is not one straight line, so not a linear function. It is called "piecewise linear," which is different.

8x - x2+ 12x +30

6x+12x +30

18x +30

8x- x2 +12x +30

-4x -x2 + 30

If the x2 was a mistake ignore the second one. The first should be correct.

Length in units:

Use phytogoras theorem or measure it by a ruler if your using a graph paper

AB = 5.65 units

AC = 5.83 units

CB = 1.41 units

Perimeter =5.65 + 5.83 + 1.41 = 12.89 units

Area = 1/2 * 1.41 * 5.65 = 3.98units

**Answer:**

12

**Step-by-step explanation:**

-48/(-4)

= -1/(-1) * (48/4)

= 1 * 12

= 12
