Answer:
-5 = x
Step-by-step explanation:
First you begin with adding 5 to the other side of the equal sign.
Why? because you want to get "x" by itself, in other words, isolate the variable. and by adding 5 you make 0 on that side
So -10+5 = 5
Therefore -5 = x

Answer:
-4 ≤ y < ∞
Step-by-step explanation:
The graph shows the range (vertical extent) has a minimum value of -4, and includes all y-values greater than or equal to that value.
In interval notation, the range is [-4, ∞).
Answer:
(x + 1)² = (2x)²
(1 + 1)² = (2(1))²
2² = 2²
4 = 4
(-1 + 1)² = (2(-13))²
(-12)² = (-26)²
Not true
x = -13 satisfies neither
Answer:
Addition property of equality.
Step-by-step explanation:
You are adding something to both sides of the equation.
