Answer:

infinitely many solutions.

Step-by-step explanation:

y=4x

y-4=4 (x-1)

Lets substitute the first equation into the second equation.

4x -4 = 4(x-1)

Distribute

4x-4 = 4x-4

Subtract 4x from each side

4x-4x-4 =4x-4x-4

-4=-4

This is always true.  X can be anything.  We have infinite solutions

What is the mean median and mode for 50, 55,42,38,163,55,61​
Likurg_2 [28]

Answer:

Mean: 67.7 (rounded to the nearest tenth)

Median: 52.2

Mode: 55

Step-by-step explanation:

To find the the mean is to take all the numbers, all them together and divide by how many numbers there is. 50+55+42+38+163+55+61= 564 then divided by 6 is 67.7

to find the median is to put all the numbers in order, (I prefer to go increasing order) and then find the middle number. If there is no  middle number you take the two numbers around it and subtract them from one n another.

Mode is to find the most common number. Whichever number repeats itself
