Answer:
(18-2)
Step-by-step explanation:
Use the formula of PEMDAS to determine which is first.
The p stands for parentheses so you would perform that operation first.
Answer:
3/5 is the answer
Step-by-step explanation:
5/5-2/5=3/5
-The equation is actually
5x^2 -2x+1=0;
-The discriminant is b^2 -4ac=4-4•5•1=4-20=-16
-this means that the equation has no real number solutions
Answer:
600 m
Step-by-step explanation:
The circumference of a tire is the distance around it. The distance around these tires is 1 m.
Since the tires revolve 15 times per second, this means every second the tires travel 15 m.
This means that in 40 seconds, the tires travel
15(40) = 600 m.
Answer:
B
Step-by-step explanation:
You are making composite functions, since all the answers provided dont fit, I only suggest to clearify that the lone term in the B option, is actually 45x and not 45.
If this is the case, composite functions means that you eval the expresion g(x) in every x variable found in f(x).
Using this, it gives you that f(g(x))=
