Answer:x=2 and y=3
Step-by-step explanation:
Given that y=2x-1
Then, 3x+2y=12
3x+2(2x-1)=12
3x+4x-2=12
7x=14
x=2
y=2(2)-1
y=3
Mean=average=sum of terms/number of terms...
(25+17+38+11+24)/5
115/5
23
X^3 +3x^2 +5x +3 / x+1 = x^2 +2x +3
x^3 +x^2
------------
0 2x^2 +5x
2x^2 +2x
----------------
0 3x +3
3x +3
---------
0 0
so the 3rd choice is right sure
Answer:
y=4,5
Step-by-step explanation:
Anything inside an absolute value will become postive.
So, 2y-9 can be -1 because the absolute value of -1 is 1.
Knowing this,
2y-9 = 1
or
2y-9 = -1
2y-9=1
2y=10
y=5
and
2y-9=-1
2y=8
y=4
y=4,5
