Answer:
or 
Step-by-step explanation:
first use the y2-y1/x2-x1 formula then use y=mx+b after
plug in 2 for y2 and -1 for y1
plug in -5 for x2 and 5 for x1
=
2+1=3
-5-5=-10
is ur slope
_____________________
this is the y=mx+b formula *extra info ig*
i usually use the first point for this but u can use watever point u want
plug in 5 for x
plug in -1 for y
and plug -3/10 for m
-1=-3/10(5)+b
-3/10*5=-3/2
-1=-3/2+b
add -3/2 on both sides
-1+3/2=1/2
1/2=b and b is ur y-intercept
y=-3/10x+1/2
hope this helps
Answer:
B. -7j-k-1
Step-by-step explanation:
Simplify:
1. IDENTIFY LIKE TERMS
<em>10k</em>+17-7j-18-<em>11k</em>
- <em>10k and -11k are like terms since they have the same variable.</em>
- 17 and -18 are like terms since they are regular numbers.
2. COMBINE LIKE TERMS
-7j-<em>k</em>-1
Hi there!
The answer is:

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%
