<span>Rational
expressions are defined as the quotients of two integers in which the
denominator does not equal to zero. Thus, the numerator and denominator would
be polynomials, which is a form of a system analogous to the integers under the
operation of addition, subtraction and multiplications. Therefore, the key
numbers of rational expressions are its variables in the numerator and/ or
denominator.</span>
Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for a linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.

Answer:
-3a+8
Step-by-step explanation:
f(a)=-2a +5
s(a)= a-2-2a=-a+2
We are asked to determine
f(a) +g(a)
= (-2a +5)+ (-a+2)
=-2a+5-a+2
=-2a-a+5+2
=-3a+8
