X+4(-2)=-2 solve for X

x = 6

Step-by-step explanation:

Remember to follow PEMDAS. Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Note that:

PEMDAS =

& is the order of operation that you follow.

First, multiply 4 with -2:

4 * -2 = -8

x + (-8) = -2

x - 8 = -2

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 8 to both sides:

x - 8 (+8) = -2 (+8)

x = -2 + 8

x = 8 - 2

x = 6

x = 6 is your 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,
