What is the solution to the equation the square root of 2x + 10, -6 = 2?

x=-1

Step-by-step explanation:

x = 27 is the solution to the equation of √(2x + 10) - 6 = 2

Step-by-step explanation:

√(2x + 10) - 6 = 2

                +6     +6

√2x + 10 = 8

2x + 10 = 8^2

2x + 10 = 64

     -10     -10

2x = 54

/2     /2

x = 27

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required 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,
