Answer:
y=2x-1
Step-by-step explanation:
straight line equation
y=mx + c
find gradient(m) first,use formula;
m=3-7/2-4
m= -4/-2
m=2
use one the coordinates
(2,3)
3=2(2)+c
3=4+c
c=3-4
c = -1
y = 2x - 1
2x+3
Let x be the number
twice a number
2x
3 more than
7 days in a week, 3 days a rotation.
multiples of 7: 7, 14, 21, 28
multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24
the LCM is 21, because it is the smallest multiple of both numbers. there will be 21 more days until you take dance class on Mondays
Answer: 27.42 units
6 + 6 + 6 = 18
C= 1/2 3.14d
1/2 x 3.14 x 6
3.14 x 3
=9.42
18+9.42 = 27.41
