Classify each table of values. You may choose from the following options:

Kamila [148]

1. exponential

40-32 = 8

32-25.60 = 6.4

6.4 * 1.25 = 8

25.60-20.48 = 5.12

5.12*1.25 = 6.4

2. exponential

32-24 = 8

24-18 = 6

8/6 = 1.33

18-13.5 = 4.5

6/4.5 = 1.33

3.neither

26-23.4 = 2.6

23.4 - 21.06 = 2.34

21.06-19.2 = 1.86

4. neither

38-30.4 = 7.6

30.4-24.32 = 6.08

24.32-20.22=4.1

Quick algebra 1 question for some points!

Kazeer [188]

$\frac{y}{x} = \frac{4}{ - 3} = \frac{8}{ - 6} = \frac{12}{ - 9} \\ this \: relation \: holds \: so \: y \: varies \\ directly \: with \: x$

$\frac{ 4}{3} m = \frac{8}{ - 6} \\ m = \frac{ \frac{ - 8}{6} }{ \frac{3}{ - 4} } = \frac{8 \times 4}{6 \times 3} = \frac{32}{18} = 2 \\ multipling \: by \: 2$

$\frac{y}{x} = \frac{ - 40}{ - 0.5} = \frac{8}{2.5} = \frac{5}{4} \\ \frac{y}{x} = 80 = 3.2 = 1.25 \\ this \: is \: untrue \: so \: y \: is \: not \\ varying \: directly \: with \: x$

$no \: constant \: of \: variation$
