Given your ordered pair you would assume a = 5, b = 2
Set up both equations 
5 + 2 = 7
7 = 7 (the numbers are equal so this correct)
2(5) - 8 = 2
10 - 8 = 2
2 = 2 (the numbers are equal so this is also correct)

Because both equations work with the ordered pair they <em>are</em><span> the solution of the given system.</span>

If f(x) = 3x – 4 and g(x) = x, find the value of f(3) – g(2).
Mamont248 [21]

Answer:

3

Step-by-step explanation:

f(3) = 3(3)-4

f(3)= 9-4

f(3) = 5

g(2) = (2)

g(2) = 2

f(3)-g(2) = ?

(5) - (2) = ?

(5) - (2) = 3

Evaluate the piecewise function at the given values of the independent variable
snow_lady [41]
A) For f(-1) we use the part of the piecewise function for when x < 0 because -1 < 0. Plug in -1 for x:

2(-1) + 3 = 1

b) For f(0), we use the part for when x \geq 0.

4(0) + 5 = 5

c) For f(2) we use the part for when x \geq 0.

4(2) + 5 = 13
