It's a linear function: y = mx + b
We have (138; 112.96); (209; 142.78)
substitute the values of x and y to the formula of slope m:
Now we have:
We must find b. Substitute the value of x and y from first pair of numbers:
Answer: y = 0.42x + 55
Answer:
Suppose the two like terms are 2 x and 3 x.So to Represent them with algebra tiles ,
Here shape of tiles = Either Square or rectangle
For example , 2 x=Draw two tiles of same color mark variable x in front of it.For, different values of x, we get different number of total tiles.
3 x= Draw three tiles of same color and mark variable x in front of it.For, different values of x, we get different number of total tiles.
For , Polynomial, 3 x -3,
Draw three tiles representing same color, Mark x over it, and then put negative sign in front of it, and draw three tiles of any other color.
To represent Zero,
We can write it as, x -x or p-p
Draw two tiles of same color , and mark negative sign in between .
General formula: A x - A x
Draw A tiles of same color, twice.And mark negative sign in between.
