Answer:
Step-by-step explanation:
This is a d = rt problem; but since it is linear, then proportions will work too. Set up the proportion with miles on top and hours on the bottom:

Then put the numbers in where they go, keeping in mind that miles goes with miles and hours goes with hours in the ratios, and that our unknown is time (hours):
and cross multiply to solve:
638x = 4466 so
x = 7 hrs
The missing number is 4/6
the number line goes 1/6 2/6 3/6 4/6 5/6 6/6
Given:
The function is
.
To find:
The function
.
Solution:
We have,

Substitute f(x)=y.

Interchange x and y.

Divide both sides by 3.

Taking power 4 on both sides.

Subtract 7 from both sides.


Substitute
.

Therefore, the correct option is C.
Answer:
y=32x shows a proportional relationship.
Step-by-step explanation:
We need to find an equation that shows the proportional relationship.
If x and y are proportional to each other, it will look like,
y = mx
Where
m is constant of proportionality
Out of 4 option, option (4) is y=32x, it shows the proportional relationship where the value of m is equal to 32.
