What is 8×5y×7=2y+4+2498

Hope this helps!

Step-by-step explanation:

8*5y*7=2y+4+2498

We move all terms to the left:

8*5y*7-(2y+4+2498)=0

We add all the numbers together, and all the variables

8*5y*7-(2y+2502)=0

Wy multiply elements

280y*7-(2y+2502)=0

We get rid of parentheses

280y*7-2y-2502=0

We add all the numbers together, and all the variables

-2y+280y*7-2502=0

Wy multiply elements

-2y+1960y-2502=0

We add all the numbers together, and all the variables

1958y-2502=0

We move all terms containing y to the left, all other terms to the right

1958y=2502

y=2502/1958

y=1+272/979

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,
