Answer:
Step-by-step explanation:
x - 3y = -16
x + 2y = 4
-x + 3y = 16
x + 2y = 4
5y = 20
y = 4
x + 2(4) = 4
x + 8 = 4
x = -4
(-4, 4)
Is there no answer choices.
Answer:
Either 6.5 or 3.60555127546
Step-by-step explanation:
Geometric mean is given by the formula :
where a and b is the 2 numbers:
Substituting them in gives us :
= 3.60555127546
If that is wrong then it is given by the formula :
Substituting these values gives us:
(3+10)/2 = 13/2 = 6.5
I'm sorry for not being capable to have a sure answer but I dont want to stick to one and get it wrong so ...
Brainliest if one of the 2 is correct.
The two equations represent parallel
When put into y=mx+b form, they both result in the equation y= -4/5x + 4/5
This causes them to overlap, meaning that they are parallel to one another.
