Y=ax+b
for x=7, y=2
7a+b=2
for x=2, y=12
2a+b=12
7a-2a+b-b=2-12
5a= -10
a= -10/5
a=-2
2a+b=12
2*(-2)+b=12
-4+b=12
b=12+4
b=16
y=-2x+16

Answer:
Cork: Less
Wood: About the same
Metal: More dense
Step-by-step explanation:
Whether or not a block floats inside water is dependent on its density. If it is floating, it means it has a lower density. If it is sinking, it means it has a higher density. If it has the same, it will be half under and half over.
Mathematically, specific gravity can be used to support this phenomenon.
*In this context, water is our reference and the blocks are our substances.
Since Boyancy force can be described 
(the weight of the fluid disperced), having a higher density p than the reference liquid inherently will cause a greater downwards force from gravity.
Answer:
165 years old
Step-by-step explanation:
For now let his age be = x
According to the question,
4x - 500 = 160
4x = 160 + 500
4x = 660
x = 660 / 4
x = <u>165 years old</u>
