Answer:
b. -3
Step-by-step explanation:
9(2x+1) < 9x-18
(distribute the 9)
18x+9 <9x-18
(subtract 9 from both sides)
18x<9x-27
(subtract 9x from both sides)
9x<-27
(divide both sides by 9)
x<-3
Answer:
Step-by-step explanation:
Details are important because they are like pieces of a puzzle, they all work together to create the bigger picture.
Answer:
c
Step-by-step explanation:
substitute (2,1) and (5,4) into each equation
2-1=1 and 5-4=1 so c is correct
For this case we have the following equation:

We must clear the value of the variable "x" as a function of r, s and t:
If we multiply by "r" on both sides of the equation we have:

If we subtract "t" on both sides of the equation we have:

If we divide by "2" on both sides of the equation we have:

Thus, the value of the variable "x" is:

Answer:
