Answer:
Step-by-step explanation:
To calculate the distance GH use the distance formula
GH = √ ( x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = G(0, - 3) and (x₂, y₂ ) = H(8, 1)
GH =
= =
Answer:
Step-by-step explanation:
-9b + b = 2b - (b + 1)
Let's simplify by taking out the parenthesis.
-9b + b = 2b - b - 1
Now, we add like terms.
-8b = b - 1
Now, let's subtract b from both sides of the equal sign in order to isolate b.
-8b - b = b - 1 - b
Simplify!
-9b = -1
Divide both sides by -9.
-9b ÷ b = -1 ÷ -9
Simplify.
