Y=mx+b
lines are parallels so m=2
y=2x+b
line passing through the point (4,2), so x=4 y=2
put these value in equation
2=2*4+b
2=8+b
b=2-8
b=-6
y=2x-6
Answer: y=2x-6

Answer:
147/64 or 2.296875 as a decimal
Step-by-step explanation:
5 1/4=20/4+1/4=21/4
2 2/7=14/7+2/7=16/7
(21/4)/(16/7)=
(21/4)*(7/16)=
(21*7)/(4*16)=
147/64
which equals 2.296875 in decimal form
Zero because is itself an eq.
The solution of the system is A. (2, 1)
The distance is 52.5 cm when weight is 7kg
Step-by-step explanation:
Distance is 15 cm when weight is 2 kg
We need to find the distance d when weight is 7 kg
Since distance and weight varies directly so,
Solving the above expression:
So, The distance is 52.5 cm when weight is 7kg
