This is a false statement.
When you are solving using square roots, you need to be aware that answers can be both positive and negative. When we solve this, you see there are two possible answers.
x^2 - 9 = 0
x^2 = 9
x = +/- 3
While 3 is an answer, so is -3. If we square either of those numbers, we get 9, which will satisfy the equation.
32/3.2 = 3.2c/3.2
c = 32/3.2
c = 10
The model will be 5 times longer that stated.
E.g if the model is said to be 10 feet long using this scale.
10*5=50
50 feet
Answer: The answer is the second equation (y = 3x-4 and y = -1/3x - 2)
Step-by-step explanation:
This is because two lines are perpendicular when the slopes of the equations are negative reciprocals from each other.
