The values of x in f(x) = 3|x - 2| + 6 when f(x) = 18 are 6 and -2
How to determine the value of x?The function is given as:
f(x) = 3|x - 2| + 6
The value of f(x) is
f(x) = 18
So, we have:
3|x - 2| + 6 = 18
Subtract 6 from both sides
3|x - 2| = 12
Divide both sides by 3
|x - 2| = 4
Remove the absolute bracket
x - 2 = 4 or x - 2 = -4
Add 2 to both sides
x = 6 or x = -2
Hence, the values of x are 6 and -2

Select all that apply.
A. x = 0
B. x = 3

D. x = -4
The domain restrictions on the rational function [tex]\frac{50}{4x - 12} + \frac{x- 4}{x^2 + x - 12} = \frac{x}{2}[/tex] are (b) x = 3 or and (d) x = -4
How to determine the domain restrictions?The function as expressed in the correct format is:
[tex]\frac{50}{4x - 12} + \frac{x- 4}{x^2 + x - 12} = \frac{x}{2}[/tex]
Factorize the denominators of the fractions
[tex]\frac{50}{4(x - 3)} + \frac{x- 4}{x^2 + 4x- 3x - 12} = \frac{x}{2}[/tex]
Factor out x and -3
[tex]\frac{50}{4(x - 3)} + \frac{x- 4}{x(x + 4)- 3(x + 4)} = \frac{x}{2}[/tex]
Factor out x + 4
[tex]\frac{50}{4(x - 3)} + \frac{x- 4}{(x- 3)(x + 4)} = \frac{x}{2}[/tex]
Set the denominators to 0
4(x - 3) = 0
(x - 3)(x + 4) = 0
Solve for x:
4(x - 3) = 0 ⇒ x = 3
(x - 3)(x + 4) = 0 ⇒ x = 3 or x = -4
This means that the domain restrictions on the rational function are (b) x = 3 or and (d) x = -4

9t-(2t-4)=25 I’m not sure how to use the distributive property to solve for t
Answer:
t = 3
Step-by-step explanation:
Given: 9t - (2t - 4) = 25
Distributive property: a(b + c) = ab + ac
1. Distribute '-' or '-1'
9t + -1(2t) + -1(-4) = 25
9t - 2t + 4 = 25
2. Combine like terms
7t + 4 = 25
3. Subtract 4 from both sides
7t + 4 - 4 = 25 - 4
7t = 21
4. Divide both sides by 7 to isolate the variable
7t ÷ 7 = 21 ÷ 7
t = 3

The slope and length of segment DE in the given triangle are: 0.5, and 1.6 units respectively.
What is the Slope of Parallel Lines?The slope of lines that are parallel to each other are always the same.
Segment DE is parallel to segment BC in triangle ABC.
Since slope of BC is 0.5, slope of DE would also be: 0.5.
Since E and D are the the midpoints of AC and AB respectively, it means that:
Length of DE = 1/2(length of BC)
Length of DE = 1/2(3.2)
Length of DE = 1.6 units
Therefore, slope of DE is: 0.5
Length of DE is: 1.5 units.
