The answer is B
Because when you graph it in the calculator you get x=-136 and that goes to one to one function on the graph
Answer:
-6.1 - (-3.13) = -2.97
(f+g)(x)=f(x)+g(x)=(2x-6)+(4x+7)=6x+1
(f-g)(x)=f(x)-g(x)=(2x-6)-(4x+7)=-2x-13
(fg)(x)=f(x)×g(x)=(2x-6)(4x+7)=8x^2-10x-42
(f+g)(-2)=f(-2)+g(-2)=(2(-2)-6)+(4(-2)+7)=-11
4x + 1 → C
(f + g)(x) = f(x) + g(x) = 3x - 1 + x + 2 = 4x + 1
To find the tip:
28 x 15/100 = 4.2 dollars
Add the tip to the cost of the lunch gives us the total cost:
28 + 4.2 = 32.2
