show all work to solve the equation for x. if a solution is extraneous, be sure to identify it in your final answer.
squareroot of x -2 + 8=x

The solution is

Step-by-step explanation:

we have

Solve for x

Subtract 8 both sides

Squared both sides

Expand the right side

Solve the quadratic equation by graphing

The solutions are x=6, x=11

see the attached figure

Verify the solutions

For x=6

substitute the value of x in the original equation

therefore

x=6 -----> is an extraneous solution

For x=11

substitute the value of x in the original equation

 ---> is true

therefore

The solution is

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

is should be y = 5x
