Answer:
Step-by-step explanation:
I can not see your answers to choose but with this equation for 2 variables, you can replace the values of x and y and see if that is right or not.
For example, to know (-2,5) is a solution, you replace x= -2 and y= 5
into this equation: -3x -y = 6
and you have: -3*(-2) -5 =6
or 6-5 =6, and you find that is impossible, so (-2.5) is not a solution.

Answer:
Step-by-step explanation:
x^2 + 44^2 = 55^2
x^2 + 1936 = 3025
3025-1936 = 1089
sqrt(1089) = 33
x = 33
Answer:

2. not factored
3. factor
Step-by-step explanation:
Answer:
The inequalities are used as:
a > b (a is greater than b)
a < b (a is smaller than b)
a ≤ b (a is smaller than or equal to b)
a ≥ b (a is greater than or equal to b)
a ≠ b (a is different than b)
Now, let's apply these for our two numbers.
-8 and -13
We know that for negative numbers, the larger absolute value means that the number is smaller, then we relate these numbers in the next 3 ways.
-8 > -13 (-8 is greater than -13)
-13 < 8 (-13 is smaller than -8)
-13 ≠ -8 (-13 is different than -8)
