That is too many questions for one post. It would be much better if you posted one question at a time and made an attempt at an answer, so we can help you understand the concepts better.
We are not here to "do homework" or to take the place of reading the assignment.
<<1. what is the value of |x-2| when
x = -5? >>
If x = -5, than x -2 = -7.
The absolute value signs | | then tell you to change the sign, since the number inside is negative. Thus
|x-2| = 7

Read my previous answer. Don't just dump your questions here en masse and expect us to do them for you.
23. To find the slope of a line parallel to a given line represented by the equation x = 2y - 3, we can start by rearranging the equation into slope-intercept form (y = mx + b), where m is the slope.
In this case, we have x = 2y - 3. To isolate y, we can add 3 to both sides of the equation:
x + 3 = 2y
Then, divide both sides by 2 to solve for y:
y = (x + 3)/2
Now we can see that the slope of the given line is 1/2 (the coefficient of x).
Since lines that are parallel have the same slope, the slope of any line parallel to x = 2y - 3 will also be 1/2.
19. To find the solution to the system of equations:
Y = 4x - 8
Y = 2x
We can solve this system using the substitution method. We substitute one equation into the other and solve for x.
Substituting the second equation (Y = 2x) into the first equation, we get:
2x = 4x - 8
Simplifying, move 2x to the right side:
0 = 4x - 2x - 8
Combining like terms:
0 = 2x - 8
Next, add 8 to both sides:
8 = 2x
Finally, divide both sides by 2:
4 = x
Now that we have the value of x, we can substitute it back into either of the original equations to solve for y. Let's use the second equation:
Y = 2(4)
Y = 8
So, the solution to the system of equations is x = 4 and y = 8.
16. To determine which graph represents the function f(x) = -3x - 1, you can identify the slope-intercept form of the equation. In this case, the equation is already in slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept.
From the equation, we can identify that the slope (m) is -3, and the y-intercept (b) is -1.
Now, looking at the graphs, find the one that has a slope of -3 and a y-intercept of -1. That graph will represent the function f(x) = -3x - 1.
12. To find the solution to the system of equations:
Y = 2x - 4
Y = x
We can once again use the substitution method by substituting one equation into the other and solving for x.
Substituting the second equation (Y = x) into the first equation, we get:
x = 2x - 4
Next, subtract x from both sides:
0 = x - 4
Then, add 4 to both sides:
4 = x
Now that we have the value of x, we can substitute it back into either of the original equations to solve for y. Let's use the second equation:
Y = 4
So, the solution to the system of equations is x = 4 and y = 4.
8. To find the equation of a line that includes the point (4, -3) and has a slope of -2, we can use the point-slope form of a line equation, which is:
y - y₁ = m(x - x₁)
where (x₁, y₁) represents the given point, and m represents the slope.
Substituting the values into the equation:
y - (-3) = -2(x - 4)
Simplifying, we get:
y + 3 = -2x + 8
Moving the variables to one side of the equation:
2x + y = 5
Therefore, the equation of the line that includes the point (4, -3) and has a slope of -2 is 2x + y = 5.
1. To find the value of |x - 2| when x = -5, we can substitute the given value into the absolute value expression.
|x - 2| = |-5 - 2|
Simplifying, we get:
|x - 2| = |-7|
Since an absolute value represents the distance from zero, |-7| is equivalent to 7.
Therefore, the value of |x - 2| when x = -5 is 7.
