1/2 x + 1 = –x + 8 answer options 7 1/2 14 18

x = 14

collect terms in x on the left side of the equation and numeric values on the right

add x to both sides

- x + x + 1 = 8

x + 1 = 8 ( subtract 1 from both sides )

x = 7 ( multiply both sides by 2 )

x = 14

entering that problem on the tube might get you an answer

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,
