No solution
Step-by-step explanation:
7x-4=7x+15
-4 = 15 = not true
Answer: 571
To get this answer, we first need to compute the value of f(4). This happens when we plug x = 4 into f(x)
f(x) = 5x + 4
f(4) = 5*4+4 ... each x replaced with 4
f(4) = 20+4
f(4) = 24
Now replace every 'x' in g(x) with f(4) like so
g(x) = x^2 - 5
g(x) = ( x )^2 - 5
g(f(4)) = ( f(4) )^2 - 5 .... every x replaced with f(4)
g(f(4)) = ( 24 )^2 - 5 ... see note below
g(f(4)) = 576 - 5
g(f(4)) = 571
note: the f(4) on the right hand side of that equation is replaced with 24, because we found earlier that f(4) = 24. In other words, f(4) is the same as 24.
Answer:
68% 32%
73.5% 26.5%
Step-by-step explanation:
Start:
total number = 561 + 264 = 825
glucose aversion = 561
percent = 561/825 × 100% = 68%
no glucose aversion: 264
percent = 264/825 × 100% = 32%
End:
total number = 441 + 159 = 600
glucose aversion = 441
percent = 441/600 × 100% = 73.5%
no glucose aversion: 159
percent = 159/600 × 100% = 26.5%
Answer:
Step-by-step explanation:
The cost function has 3 branches,
- Consumptions less than 500
- Consumptions less than 1000
- consumptions above a 1000
So the first branch the consumer pays 6 dollars plus .10cents for any additional kWh (k)
In the second, they pay the same as the first up to 500kWh, and after that they pay 0.11 for the additional kWh above 500: (k-500) but bellow 1000
In the third branch, for consumptions above 1000, they pay the fix amount, plus .10 for the first 500 (
) , .11 for the additional 500 (
) , and finally 0.15 for consumptions above 1000:
