Answer: The Subtraction Property of Equality
In the problem that Jax solved he subtract 5 from both sides of the equation. This is an example of the subtraction property of equality.
The property states that if you subtract the same amount from both sides of an equation the equation remains the same.
Answer:
Step-by-step explanation:
A'B' is 1/2 times the AB as the scale factor is 1/2.
<u>Find the length of AB using distance formula.</u>
- AB =

<u>And find A'B':</u>
- A'B' = 1/2*2

Correct choice is A
Answer:
4
Step-by-step explanation:
Recall a linear function, is a line on a graph made up of an infinite amount of points which satisfy the relationship. That means at x=3 there is a specific point on the line with an output. The value of a function at x=3 asks, what is the output y value for the input x value?
To find it, we locate 3 on the x-axis. We draw a vertical line directly to the line following the grid line. We mark the point on the line. We then draw a horizontal line directly to the y-axis following the grid line. The point we hit on the y-axis is the value of the function.
Here it is 4.
