Answer:
y=-1/2x+3/2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-1)/(5-1)
m=-2/4
m=-1/2
y-y1=m(x-x1)
y-1=-1/2(x-1)
y=-1/2x+1/2+1
y=-1/2x+1/2+2/2
y=-1/2x+3/2
Step-by-step explanation:
A)y=8
B)k=10
5y=72-32
5y=40
y=8
1/2k+24=29
k+48=58
k=58-48
k=10
Answer:
k
Step-by-step explanation:
N=m-2
m-2n=8, using n from above in this equation yields:
m-2(m-2)=8 perform indicated multiplication
m-2m+4=8 combine like terms on left side
-m+4=8 subtract 4 from both sides
-m=4 divide both sides by -1
m=-4
So the correct answer is A) m=-4
Answer:
1) The length of 
is 20.
2) The length of 
is 17.
Step-by-step explanation:
1) If 
and 
, then we can use the following proportionality ratio:
(1)
Where 
is the length of segment 
.
If 
, then the value of is:
The length of is 20.
2) If 
and 
, then we can use the following proportionality ratio:
(2)
Where is the length of segment 
.
If 
, then the value of is:
The length of is 17.
