Answer:
Step-by-step explanation:
Work to isolate x on one side of the inequality:
Therefore the answer is all x values larger than or equal to -30
12÷4=3 and 36÷12=3
so the ratio is same
therefore it is a geometry sequence
=108
so the ratio is same
therefore it is a geometry sequence
=108
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
While the point-slope equation of a line is given by:
Where:
m: It's the slope
It is a point through which the line passes
In this case we have a line through:
(8,4) and (0,2)
Therefore, its slope is:
Its point-slope equation is:
Then, we manipulate the expression to find the equation of the slope-intersection form:
Therefore, the cut-off point with the y-axis is
