Answer:
(11, 11)
Step-by-step explanation:
Solve by substitution:
1. set the equations equal to each other
2. simplify
3. substitute the value of x into an equation
Answer: C (-7/18)
Step-by-step explanation: you flip the denominator and numerator and keep the negative
Answer:
81
Step-by-step explanation:
Range = maximum - minimum so here, we'd have:
52 = max - 29
Add 29 to both sides to solve.
Answer:
> 1
Step-by-step explanation:
A scale factor greater than 1 will produce an enlargement
A scale factor less than 1 will produce a reduction
Since the image is larger than the pre- image the scale factor > 1
Why not? Because every math system you've ever worked with has obeyed these properties! You have never dealt with a system where a×b did not in fact equal b×a, for instance, or where (a×b)×c did not equal a×(b×c). Which is why the properties probably seem somewhat pointless to you. Don't worry about their "relevance" for now; just make sure you can keep the properties straight so you can pass the next test. The lesson below explains how I kept track of the properties.
