D. fill 3/10 for r so
- 4 \frac{4}{9} ( \frac{3}{10} )
-  \frac{36 + 4}{9}  \times  \frac{3}{10}
-  \frac{40}{9}  \times  \frac{3}{10}
-  \frac{120}{90}
-  \frac{4}{3}  \: or \:  - 1 \frac{1}{3}

E. fill -2(2/3) for W
- 3 \frac{1}{8} ( - 2 \frac{2}{3} )
\frac{ - 24 + 1}{8}  \times  \frac{ - (6 + 2)}{3}
- \frac{25}{8}  \times  \frac{ - 8}{3}
-  \frac{ - 200}{24}
\frac{25}{3}  \: or \: 8 \frac{1}{3}
F. fill (-3/4)
((\frac{3}{8} )( \frac{ - 3}{4} )) + (( \frac{1}{8} )( \frac{ - 3}{4} ))
\frac{3  \times   - 3}{8 \times 4} +  \frac{1 \times  - 3}{8 \times 4}
- \frac{9}{32}   -  \frac{3}{32}
- \frac{12}{32}  =   - \frac{3}{8}

What equation represents the proportional relationship displayed in the table?
KATRIN_1 [288]

Answer:

y=6x

Step-by-step explanation:

Given:

The table is given as:

x   0    4       7       8

y   0    24    42     48

The relationship between 'x' and 'y' is a proportional relationship.

A proportional relationship is one in which one variable varies directly with the other by a factor of 'k' also known as constant of proportionality and k\ne 0

A proportional relationship is given as:

y=kx

Now, we plug in 'x' and 'y' values and find the value of 'k'.

Let x=4\ and\ y=24

24=k\times 4\\\\k=\frac{24}{4}=6

Therefore, the constant of proportionality is 6. Hence the complete equation is given as:

y=6x
