Answer:
nothing
Step-by-step explanation:
all of them seem to be right. if you need practice work on alternate interior angles, exterior angles
Step-by-step explanation:
To find the answer we first multiply 129 by 0.7 since the price descresed 30 percent. each percent is equal to 0.01.
129 * 0.7 = 90.3
Then we multiply 90.3 by 1.0875 since that is the sales tax
90.3 * 1.0875 = 98.2
so the cost is 98.2
Answer:
7) (f+g)(x) = 4^x +5x -5
8) (f-g)(x) = 4^x +x +5
Step-by-step explanation:
7) add the two expressions.
(f+g)(x) = f(x) +g(x) = (4^x +3x) +(2x -5)
(f+g)(x) = 4^x +5x -5
__
8) subtract g(x) from f(x).
(f-g)(x) = f(x) -g(x) = (4^x +3x) -(2x -5) = 4^x +3x -2x +5
(f-g)(x) = 4^x +x +5
