Please help me find the x

x = 2

Step-by-step explanation:

Basic proportionality theorem,

AB = AD + DB = 4+6 = 10

CB = CE + EB = x + x +1 = 2x +1

Cross multiply

10*(x+1) = 6*(2x+ 1)

10*x + 10*x = 6*2x + 6*1

10x + 10 = 12x + 6

Subtract 10x from both sides

10x + 10 - 10x = 12x + 6 - 10x

10 = 2x + 6

Subtract 6 form both sides

10 - 6 = 2x + 6 - 6

4 = 2x

Divide both sides by 2

4/2 = 2x/2

2  = x

x = 2

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

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,
