I want to say it is savings but I can be wrong. But I believe it is savings.
Answer:
2x^4+4x^2+2
Step-by-step explanation:
f(x) = x^2+1
g(x) = 2x^2
g(f(x))=
Replace x in the function g(x) with the function f(x)
=2( x^2+1)^2
= 2( x^2 +2x^2 +1)
= 2x^4+4x^2+2
Answer:
A. More students prefer Model A1 calculators than the Model C3 calculators.
Answer:
The ordered pair is not a solution of the equation
Step-by-step explanation:
we know that
If a ordered pair is a solution of a linear equation, then the ordered pair must satisfy the linear equation
we have

Substitute the value of x and the value of y of the given ordered pair in the linear equation and analyze the results
For x=-1, y=15


----> is not true
so
the ordered pair not satisfy the equation
therefore
The ordered pair is not a solution of the equation
The answer is 2.
3x+2y=3
2x-2y=7
solve both the equations
3x+2y=3
+2x-2y=7
5x=10
so we get
x=2
