3 or 4
-3 or 4
Answers
minus x+12 both sides
x^2-x-12=0
factor
(x-3)(x+4)=0
set each to zero
x-3=0
x=3
x+4=0
x=-4
x=3 or -4
answer is first one

a - { a - [ a- (2a - b) + 3a ]}

= a - {a - (a - 2a + b + 3a)}
= a - {a - (2a + b)}
= a - (a - 2a -b )
= a - (-a - b)
= a + a + b
= 2a + b

A graph of the linear function y = 1/2(x) + 1 is shown in the image attached below.
What is the slope-intercept form?
In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;
y = mx + b
Where:
- m represent the slope or rate of change.
- x and y are the points.
- b represent the y-intercept.
Since the given linear function y = 1/2(x) + 1 is in slope-intercept form, we would start by plotting the y-intercept:
y = 1/2(x) + 1
y = 1/2(0) + 1
y = 1 ⇒ (0, 1)
y = 1/2(-8) + 1
y = 1 ⇒ (-8, -3)
y = 1/2(-4) + 1
y = 1 ⇒ (-4, -1)
y = 1/2(2) + 1
y = 1 ⇒ (2, 2)
y = 1/2(6) + 1
y = 1 ⇒ (6, 4)
Next, we would use an online graphing tool to plot the given linear function for the values in its domain { -8,-4,0,2,6} using table, as shown in the graph attached below.

Final answer:
To plot the ordered pairs for the given domain of a linear function, substitute each value of x into the equation and solve for y.
Explanation:
To plot the ordered pairs for the values in the given domain, we substitute each value of x into the equation and solve for y. Let's do that for each value in the domain:
- For x = -8, y = (1/2)(-8) + 1 = -4 + 1 = -3. The ordered pair is (-8, -3).
- For x = -4, y = (1/2)(-4) + 1 = -2 + 1 = -1. The ordered pair is (-4, -1).
- For x = 0, y = (1/2)(0) + 1 = 0 + 1 = 1. The ordered pair is (0, 1).
- For x = 2, y = (1/2)(2) + 1 = 1 + 1 = 2. The ordered pair is (2, 2).
- For x = 6, y = (1/2)(6) + 1 = 3 + 1 = 4. The ordered pair is (6, 4).
The ordered pairs for the given domain are (-8, -3), (-4, -1), (0, 1), (2, 2), and (6, 4).
