First, It's a function.
Second, domain is {a,b,c,d}
Third, range is {x,y,z}
Reason why it's function because
1. A single value in Input doesn't have 2 lines connected (domain must not be repetitive.)
2. All Inputs have lines connected to Output (if not then not a function.)
Answer:
You can rewrite it to figure out the square root of 20 which would give you the value 4.47214...
Step-by-step explanation:
Answer:
62.5%
Step-by-step explanation:
the question is worded weirdly but basically since they're saying "<em>given that a state does not use nuclear power</em>", you can ignore the ones that do use nuclear power.
20 + 12 = 32
and then u have to find the percentage that do use coal (20). to do that all you have to do is divide then move the decimal place backwards 2 times
20 ÷ 32 = 0.625
62.5%
rs + st = rt Plug in the values
3x + 1 + 2x - 2 = 64 Combine like terms (1 and -2)
3x -1 + 2x = 64 Combine like terms (3x and 2x)
-1 + 5x = 64 Add 1 to both sides
5x = 65 Divide both sides by 5
x = 13
