The equation that shows the relationship between the number of round trips, x and the number of kilometers, y Scott walked is y = 3x
Each round trip = 3 km
x = number of rounds
y = number of km he has walked in all.
1 rounds = 3 km
Therefore,
x rounds = 3x km
Each round of trip covers 3km. This means for each round of trip a distance of 3km is covered. The total distance or number of kilometers is represented with y.
The equation to show the relationship between x(number of rounds) and y (number of km) can be represented below

Answer:
mean absolute deviation is <em>8</em>
Step-by-step explanation:
to find mean absolute deviation, you subtract your mean from each of your values, and make them all positive, (even if u get a negative..)
then you add all your new answers up and divide by how many numbers there are (basically just find mean of your new set of data...)
<em>Hope this helps you in the future!!</em>
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 2 is in this form with slope m = 3
• Parallel lines have equal slopes, hence
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (10, 1) into the partial equation
1 = 30 + c ⇒ c = 1 - 30 = - 29
y = 3x - 29 ← in slope- intercept form
Subtract y from both sides
0 = 3x - y - 29 ( add 29 to both sides )
29 = 3x - y, thus
3x - y = 29 ← in standard form → B
The missing parts of the table for the function are 49, 1 and 49 respectively
<h3>How to complete the missing parts of the table?</h3>
An exponential function is a type of function which involves exponents. A simple exponential function is of the form y = bˣ
Given: the exponential function y = (1/7)ˣ
In order to find the missing parts, we have to substitute the relevant values into the function. Thus:
For x = -2:
y = (1/7)ˣ
Substitute x = -2 into the function:
y = (1/7)⁻² = 49
For x = 0:
y = (1/7)ˣ
Substitute x = 0 into the function:
y = (1/7)⁰ = 1
For x = 2:
y = (1/7)ˣ
Substitute x = 2 into the function:
y = (1/7)² = 1/49
The missing part is 49
Therefore, the missing parts of the table are 49, 1 and 49 respectively
