If (f+g)(x) = 3x to the second power + 2x - 1 and g(x) = 2x - 2, what is f(x)?
o a 3x2+1
ob. 3x2-1
oc. 3x2+4
od. 3x2-4
o e. x2 -2

A. 3x²+1

Step-by-step explanation:

(f+g)(x)=f(x)+g(x)

given that

(f+g)(x)=3x²

g(x)=2x-2

f(x)=?

put in the values

3x²+2x-1=f(x)+2x-2

subtract 2x from both sides

3x²+2x-2x-1=f(x)+2x-2x-2

3x²-1=f(x)-2

add 2 on both sides

3x²-1+2=f(x)-2+2

f(x)=3x²+1

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
