Point A and B of what? Plz show a number line or graph or table or something.
Answer:
-2.
Step-by-step explanation:
3n must be greater than 25 for the first negative term:
3n > 25
n > 25/3
n > 8 1/3.
So n = 9 and the first negative term is 25 - 3*9
= 25 - 27
= -2.
Answer: 3
Step-by-step explanation:
Start off by distributing the numbers into the parentheses:
5(-3x - 2) - (x - 3) = -4(4x + 5) + 13
-15x - 10 - (x - 3) = -16x - 20 + 13
(Note: It's super important to be careful when opening up negative parentheses! -(x-3) is not just - x - 3, it is actually -x + 3 since the negative is distributed in every number!)
-15x - 10 - x + 3 = -16x - 20 + 13
-16x - 7 = -16x - 7
-16x = -16x
0 = 0
There is an infinite number of solutions in this equation.
(When you get 0=0 when solving for a variable, that means that said variable will have infinite solutions, that is, any number plugged into the equation will work)
