Answer:
This is the given information for which system of equations would be used to find out how many dimes and quarters Amir has?
x = dimes x = 0.10 or 0.1
y = quarters y = 0.25
31 coins
worth $5.20 = 5.2
x + y = 31
0.1x + 0.25y = 5.2

Answer:
The store will sell the guitar for $58.50
Step-by-step explanation:
$45 * 1.3 = $58.50
Since the price they bought it for is $45 and the markup percent is 30%, we multiply $45 by 1.3, which will give us $58.50.
Answer:part a :yes it is a linear function because it is a straighten lined Part b : LINEAR FUNCTION Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line. When x increases, y increases twice as fast, so we need 2x. When x is 0, y is already 1. NONLINEAR FUNCTION An example of a nonlinear function is y = x^2. This is nonlinear because, although it is a polynomial, its highest exponent is 2, not 1.
