Answer:
y=x+1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(3-2)/(2-1)
m=1/1
m=1
y-y1=m(x-x1)
y-2=1(x-1)
y-2=x-1
y=x-1+2
y=x+1
Answer:
y = 1, x = - 8
or
(-8, 1)
Step-by-step explanation:
-x + 4y = 12
x + y = -7
add the equations together
0x + 5y = 5
5y = 5
y = 1
substitute y for 1 in one of the original equations to find x
x + y = -7
x + 1 = -7
x + 1 - 1 = - 7 - 1
x = - 7 - 1
x = -8
Answer:
It doesn't exist
Step-by-step explanation:
The graph must follow the handshake lemma: the sum of odd vertex degrees must be an even number: 1+3+5=9
Answer:
31.0
Step-by-step explanation:
The mean of a given set of data is the ratio of the sum of the data to the number of units that make up the data set. It is also called the average of the data set.
Given the data set {22, 34, 37, 23, 45, 21, 29, 37}. There are 8 numbers in the set. The total of these numbers
= 22 + 34 + 37 + 23 + 45 + 21 + 29 + 37
= 248
The mean = 248/8
= 31
