Answer:
30
Step-by-step explanation:
1.Substitute the x for 12.
2.Multiply the 2 by 12.
3.Then add 6 to your answer.
The rate of change is 1.
Use the slope formula 5 - 0 is the rise and 5 - 0 is the run
5/5 = 1
Answer:
Option c
or 
Step-by-step explanation:
The absolute value is a function that transforms any value x into a positive number.
Therefore, for the function
x> 0 for all real numbers.
Then the inequation:
has two cases
if
(i)
if
(ii)
We solve the case (i)

We solve the case (ii)

Then the solution is:
or 
7^4 the ^ is the exponent symbol if you did not know
7^4=2,401
X=5+y
x+y=-15
subsitute 5+y for x
5+y+y=-15
5+2y=-15
minus 5 from both sides
2y=-20
divide both sides by 2
y=-10
sub back
x=5+y
x=5-10
x=-5
the numbers are -10 and -5
