Answer:
A
Step-by-step explanation:
Distribute the (-)
6x^3y^3+x^3y^3 + 5x^2y^2 - x^2y^2 - x^2y+x^2y +xy^2 +3x+3x +2-4
Cancel out bold and add:
7x^3y^3 + 4x^2y^2 +xy^2+6x-2
The answer is C. If you substitute x for 6 and , the equation looks like this:
2(1+6)>5+8
Solve.
2(7)>13
14>13
Since 14 is greater than 13, the values make the statement true
Answer:
y = –3x + 9
Step-by-step explanation:
expand the equation y = –3(x – 3)
-3 × x is -3
-3 × -3 is +9
Answer:
Step-by-step explanation:
The total number of operations prepared by the surgeon is X.
The questions can be solved by set
For two sets A and B,
Where A= The surgery done with infections
B= Surgery done which failed
n(AᴜB) is the number of elements present in either of the sets A or B.
n(A∩B) is the number of elements present in both the sets A and B.
Y= number of surgery which succeed and are free from infection
n(AᴜB) = n(A) + (n(B) – n(A∩B) + Y
X= 2% of X + 12% of X -1.35% of x + Y
X=0.02X+0.12X-0.0135X+Y
X=0.1265X+Y
Y=X-0.1265X
Y=0.8735X
Therefore the operation s that succeed and are free from infections is 0.8735 or 87.35%
