Answer:
1) yes--common difference is 3.
Piper would make $557.5 in a week in which she made $2050 in sales
<h3>What are linear equations?</h3>
Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
<h3>How to determine the solution to the system?</h3>
A system of linear equations is a collection of at least two linear equations.
In this case, the given parameters are:
Guarantee fee = $250 per week
Commission = 15%
Let the total sales be x and the total amount be y
So, we have:
y = Guarantee fee + Commission * x
This gives
y = 250 + 15% * x
The total sales is $2050
This gives
y = 250 + 15% * 2050
Evaluate
y = 557.5
Hence, Piper would make $557.5 in a week in which she made $2050 in sales

Answer:
-4.5 , to - 2.5 , to , - 1.1 , to 0.8, to 9/5
Step-by-step explanation:
Answer:
(x + y)² = 25
Step-by-step explanation:
The expansion of (x + y)² is
(x + y)² = x² + y² + 2xy ← substitute x² + y² = 15 and xy = 5
= 15 + 2(5)
= 15 + 10
= 25
