For this case, the first thing we must do is define variables:
x: unknown number (1)
y: unknown number (2)
We now write the equations that model the problem:
their sum is 6.1:

their difference is 1.6:

Solving the system we have:
We add both equations:

Then, we look for the value of y using any of the equations:
Answer:
The numbers are:
Cause it's already hard thou
Hope this help hahahahaha
Answer:
all of them
Step-by-step explanation:
all of them seem to have the same marks
but if u get the question wrong my next bet would be to go with only C because it has the marks on the sides if that makes sense
Answer:
Option c is correct !!
Step-by-step explanation:
[ Refer to the attachment ]
As y = mx + c is an equation to represent the straight line ; we equate the given line with this equation !!
Where m is slope of the line
and c is y intercept !!
We get , m = -3/2 and c = 4
Also, two perpendicular lines follows the equation :-

Where m nth is slope of nth line !!
