What is the solution to the equation below? square root of x+5=8

Step-by-step explanation:

Radical Equation entered :

√x-5 = 8

STEP1:

Isolate the square root on the left hand side

Radical already isolated

√x-5 = 8

STEP2:

Eliminate the radical on the left hand side

Raise both sides to the second power

(√x-5)2 = (8)2

After squaring

x-5 = 64

STEP 3:

Solve the linear equation

Rearranged equation

x -69 = 0

Add 69 to both sides

x = 69

A possible solution is :

x = 69

STEP 4:

Check that the solution is correct

Original equation

√x-5 = 8

Plug in 69 for x

√(69)-5 = 8

Simplify

√64 = 8

Solution checks !!

Solution is:

x = 69

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
