Given the function f(x) = 3|x – 2| + 6, for what values of x is f(x) = 18?
Gwar [14]

Answer:

x = - 2, x = 6

Step-by-step explanation:

Given f(x) = 18 we require to solve

3 | x - 2 | + 6 = 18 ( subtract 6 from both sides )

3 | x - 2 | = 12 ( divide both sides by 3 )

| x - 2 | = 4

The absolute value function always returns a positive value, however, the expression inside can be positive or negative, thus

x - 2 = 4 ( add 2 to both sides )

x = 6

OR

- (x - 2) = 4

- x + 2 = 4 ( subtract 2 from both sides )

- x = 2 ( multiply both sides by - 1 )

x = - 2

As a check substitute these values into the left side of the equation and if equal to the right side then they are the solutions

x = 6 → 3|6 - 2| + 6 = 3|4| + 6 = 3(4) + 6 = 12 + 6 = 18 ← True

x = - 2 → 3|- 2 - 2| + 6 = 3|-4| + 6 = 3(4) + 6 = 12 + 6 = 18 ← True

Hence solutions are x = - 2, x = 6

Find the equation of the line that passes through he points (2,6) and (-2,4)
stepan [7]
First Find slope by using \frac{y2-y1}{x2-x1}

\frac{4-6}{-2-2} = \frac{-2}{-4} =  \frac{1}{2}

Now use point Slope form to find the equation of the line (y-y₁)=m(x-x₁)
(y-6)=\frac{1}{2}(x-2) 
y-6=\frac{1}{2} x-1
y=\frac{1}{2} x+5 is your equation

Five times the difference of a number and two is 29
Slav-nsk [51]

5*(n-2) = 29

5n-10=29 (distributive property)

5n-10+10=29+10 (do operations to both sides to isolate variable)

5n/5 = 39/5 (further isolate)

n = 7.8 (answer)

Your number is 7.8.
