Answer:
1st pair x=-7 and -9; 2nd pair x=2 and y=2; 3rd pair x=-1 and y=0; 4th pair x=-3 and y= 2; 5th x=-2 and y=-1; All others are not clearly written
Step-by-step explanation:
method for simultaneous equation are substitution, elimination or matrix methods
The trick to picking out functions is to pay attention to the <u>x- coordinates.</u>
F(x) = 3x + 2
g(x) = 5x - 10
g(x) - f(x) = (5x - 10) - (3x + 2)
g(x) - f(x) = (5x - 3x) + (-10 - 2)
g(x) - f(x) = 2x - 12
The answer is B.
