Answer: 1 is not a perfect square. 3 is the only prime number one less than a square.
Given:
The given point is (-4,1)
Let's check the ordered pair (-4,1) in the first equation
Hence, (-4,1) is a solution of the first equation x-5y=-9.
Now, let's check (-4,1) in the second equation.
So, (-4,1) is a solution of the second equation 4x+4y=-12.
Hence, (-4,1) is a solution of both equation in the system, then it is a solution to the overall system.
Call center A and B offers equal wages.
<h3>what is Equation?</h3>
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
The formula for wages = P/t
First, P= 15 dollars
= 1500 cents
time= 1 hour= 60 minutes
then, the unit rate is
=1500/60
= 25 cents/ min
Second, P= 25 cents
time= 1 minutes
then, the unit rate is
=25/1
= 25 cents/ min
Hence, Call center A and B offers equal wages.
