Answer:
if u substract the equations u get 4x = 1, therefore x = 1/4
Step-by-step explanation:
(8x + y) - (4x + y) = 5 - 4
4x = 1
x = 1/4
Given the data points, (x, y) of a linear function: (2, 11), (4, 10), (6, 9), (12, 6), what is the function? What is the slope?
NeX [460]
Answer:
The function is
.
The slope is
.
The y-intercept is
.
Step-by-step explanation:
Our aim is to calculate the values <em>m</em> (slope) and <em>b</em> (y-intercept) in the equation of a line :

We have the following data:

To find the line of best fit for the points given, you must:
Step 1: Find
and
as it was done in the table below.
Step 2: Find the sum of every column:

Step 3: Use the following equations to find <em>b</em> and <em>m</em>:

Step 4: Assemble the equation of a line

The graph of the regression line is:
Answer:
Step-by-step explanation:
For this question, you count backwards from 0545hrs which is 5:45 am until 7hrs is reached.
5:45 am Thursday

10:45 pm Wednesday
Therefore, Madaraka express left Nairobi at 10:45 pm on Wednesday
52% of 200
52/100=26/50=13/25•200/1= 2600/25=2600 divided by 25 is 104
The answer is 104
