Answer:
10
Step-by-step explanation:
multiply the first equation by 2 in order to be able to cancel out the -4z and the 2x
4x-30y=-20
-4x+5y=-30
50y+5y = -20+(-30)
55y=-50
The answer is 112.4 because 24.5+24.5+31.7+31.7=112.4.
Answer:
2
Step-by-step explanation:
Answer:5:15
Step-by-step explanation:
2:30+2 hour=4:30
4:30+45=5:15
The range is {2, 4, 7}.
I got this by inputting each of the domain numbers into the given function as shown:
F(6)=1/3(2)+4
F(0)=1/3(0)+4
F(9)=1/3(9)+4
x is replaced by the numbers in the domain, including the f(x) part. In any case, when you solve the problems above, the results are 2, 4, and 7 -- which constitutes the range of the function, or the set of all possible outputs. The domain constitutes the set of all possible inputs for the function.
