2n + 1 , 2n + 3 , 2n + 5
____________________________
( 2n + 5 ) + ( 2n + 3 ) = 5 × ( 2n + 1 ) - 15
4n + 8 = 10n + 5 - 15
4n + 8 = 10n - 10
Add both sides 10
4n + 8 + 10 = 10n - 10 + 10
4n + 18 = 10n
Subtract both sides 4n
4n - 4n + 18 = 10n - 4n
18 = 6n
Divide both sides by 6
18 ÷ 6 = 6n ÷ 6
n = 3
_________________________________
Thus that three numbers are :
2(3) + 1 , 2(3) + 3 , 2(3) + 5
6 + 1 , 6 + 3 , 6 + 5
7 , 9 , 11
And we're done ....
Answer:
y = x+1
Step-by-step explanation:
points (0,1) and (2,3)
slope =(y2-y1)/(x2-x1)
m = (3-1)/(2-0)
= (2/2)
m=1
the y intercept ( or where it crosses the y axis) is 1
y = mx+b
y = 1x+1
y = x+1
What is the question?
2x3 = 6
2 x 3 ones = 6
