Step-by-step explanation:
Given
In 1990; Income= $39000
In 2010; Income= $70768
Solving (a): An equation in form of f(x) = ax + b
First, we need to determine the slope, a
Taking y as income and x as year index.
When x = 0; y = 39000
When x = 20; y = 70768
Substitute these values in the above formula
Next, is to determine the formula using:
<em>Considering :When x = 0; y = 39000, we have</em>
<em /><em />
<em /><em />
<em>Make y the subject of formula</em>
<em /><em />
<em />
<em>Express y as a function of x</em>
<em /><em />
Solving (b): Income in 2005
<em>In 2005, x = 15</em>
So:
becomes

Answer:
D
Step-by-step explanation:
An inequality is an expression which means more than one number is a solution. We graph the solutions on a number line to show all possible values. We graph using circles and arrows.
- Equal to and less/greater than are graphed with filled in circles on the value.
- Only less/greater than (not equal to) are graphed with open (not filled in) circles on the value.
- We draw an arrow the direction the solutions satisfy the inequality. Generally this is the direction the inequality itself points.
This is a filled in circle on -2 so this is . This means only answers C and D are options.
Answer D points to the right.
