For the first rectangle:
- Find the distance between (-4, 3) & (-2, 6) and (2, -1) & (-4, 3)
- Multiply the distances to get the area of the rectangle.
For the second rectangle:
- Find the distance between (-4, 4) & (-1, -5) and (2, -4) & (-4, 4)
- Multiply the distances to get the area of the rectangle.
Compare areas to see which one is larger.
1.If y varies directly with x
Introduce the constant term k
2.y=kx
where k is the constant term
substitute the value of x and y to form the law
-1=3k
k=-1\3
:y=-1\3x....is the law
To find the value of y when x is 9
Reinstate the law which is y=-1\3x and substitute the value of x to find y
y=-1\3*9
y=-3
F(x)=2x-5
Insert the value of x which is x+1 ->
F(x+1)= 2(x+1)-5
Distribute ->
F(x+1)=2x+2-5
Then, add like terms->
F(x+1)=2x-3
Plug in -3n as n into the functon K(n)=4n+5
so you get
K(-3n)=4(-3n)+5
K(-3n)=-12n+5
