Drag tiles to the board to represent the expression. Use algebra tiles to model the expression. Then, use the model to help you write an equivalent expression, and complete the statements. 3(x + 2) Model the expression as 3 groups of x + 2. There are x tiles. There are + 1 tiles. The equivalent expression is Board sum: 0 Reset

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
