Answer:

Constant of proportionality is 12

The cost of buying new bicycle changes  12 dollar per week

Step-by-step explanation:

we are given

The equation as

d=12w

where

d represents the amount in dollars

w is number of weeks

now, we can compare it with

y=kx

where

k is constant of proportionality

we can compare

and we get

k=12

So,

Constant of proportionality is 12

we can see that

12=\frac{d}{w}

So,

The cost of buying new bicycle changes  12 dollar per week

A line passes through the points (7, 3) and (8, 3). What is its equation in slope-intercept form?
Sati [7]

Answer:

y=3

Step-by-step explanation:

The y values are the same, so there cannot be a slope. The (mx) part of y=mx+b is cancelled out, and is left with the b. Since the y value is forever three, the y-intercept will be 3 as well.

Therefore, the slope-intercept equation is

y=3

yan [13]

Answer:

Add 22/63

<u>Step 1:  Subtract 3/7 from both sides</u>

3/7 + n - 3/7 = 7/9 - 3/7

n = 49/63 - 27/63

n = 22/63

Answer:  Add 22/63
