Drag the tiles to the correct boxes to complete the pairs. not all tiles will be used. find the solutions to the linear equations represented by the models shown, where circles and squares are shown evenly balanced on balance beams. assume the weight of a circle is 1 unit and the weight of a square is x units.

we know that

the weight of a circle is unit and the weight of a square is units

we have circles and squares balanced on balance beams

so

the weight of the left side is equal to the weight of the right side

part a)

solve for x

subtract both sides

divide by both sides

therefore

the answer part a) is

part b)

solve for x

subtract both sides

therefore

the answer part b) is

part c)

solve for x

divide by both sides

therefore

the answer part c) is

answer: what do you mean

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
