Answer:
no because it fails the vertical line test
So let's name the numbers x and y.
we know that their sum, x+y is

and that that their difference, x-y is

so, from the last one we can find out x:
x-y=

x=

+y
we can substitute this into the first one:

+y+y =


+2y =

2y=

(7-2=5, but you have to "borrow" one because the fraction of the number from which you substract is smaller than of the other number)
so y=

then x will be
x=

+

x=
first off, let's put 8y - 5x = 11, in a slope-intercept form, so we can see what's its slope

so the slope of this line is 5/8, well then

Answer: the first one is what then the 3 one is the
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
3.3÷(0.8−3)−0.5
First think of PEMDAS
So first do parenthese
(0.8-3)=-2.2
3.3÷-2.2-0.5
Now do division
3.3/-2.2=-1.5
and now subtraction
-1.5-0.5=-2
