Solve the equation the square root of the quantity x plus 4 minus 3 equals 1 for the variable.
Kruka [31]

Answer:

x = 12

Step-by-step explanation:

sqrt(x+4) - 3 = 1

First get the sqrt all by itself on one side of the equation. Add 3 to both sides of the equation.

sqrt(x+4) = 1 + 3

sqrt(x+4) = 4

To "fix" the sqrt, that is, "undo it" and get rid of it, you have to SQUARE both sides of the equation.

(sqrt(x+4))^2 = 4^2

x + 4 = 16

subtract 4 to finish up.

x = 12

Check:

sqrt(12 + 4) - 3 = 1

sqrt16 - 3 = 1

4 - 3 = 1

1 = 1 Check!

Answer:

The answer to your question is:         y = -2x + 10

Step-by-step explanation:

Data

Point = (1, 8)

Line    y = x/2 + 3

perpendicular

slope = 1/2  but the lines are perpendicular, then slope = -2

Equation

                    ( y - y1) = m ( x - x1)

                     (y - 8) = -2(x  - 1)

                     y - 8 = -2 x + 2

                     y = -2x + 2 + 8

                    y = -2x + 10
