Solving the equation :  for y we get

Step-by-step explanation:

We need to solve for y the equation:

We need to find value of y

Solving:

Taking LCM of a, 1 we get a

Multiply both sides by a, a will be cancelled on left side

Taking y common from left side:

Divide both sides by a+1

So, Solving the equation :  for y we get

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

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,
