when 2x^2/y = w+2/4 is solved for w, one equation is w= 8x^2/y -2 which of the following is an equivalent equation to find w?

w= 8x^2+2y / y

w= 8x^2-2y / y

w= 8x^2 - 3y

w= 8x^2 - y

b. w= 8x^2-2y / y

Step-by-step explanation:

Given:

(2*x^2)/y = (w+2)/4

Isolating w, we get:

w = (8*x^2)/y - 2  

Multiplying and dividing the second term in the right-side of the equality by y, we get:

w = (8*x^2)/y - 2*y/y  

Subtracting the fractions:

w = (8*x^2 - 2y)/y

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,

answer: your correct answer is b. d.
