Answer:
x=4.5
Step-by-step explanation:
The answer would be 12+15=27 and then you add 3 so the answer will now be 30
positive numbers are to the right or up, negative numbers are to the left or down.
So this means 1 unit left and 7 units up.
For this case we have the following inequality:

We multiply both sides of the equation by -1.
By doing this, change the symbol of the inequality.
We have then:

From here, we clear the value of x.
We have then:
Answer:
The solution set is:
{x | x R, x < -12}
Answer:
See below
Step-by-step explanation:
Perpendicular lines have slopes which are negative reciprocals. Line a with the equation y = 13x + 3 has slope 13. This means Line b which is perpendicular will have slope -1/13.
The equation of line b is any equation where -1/13 is the slope/
Example: y = -1/13x + 5 or y = -1/13x - 6
