Answer:
Step-by-step explanation:
The temperature starts at 50 and increases because the slope is positive.
The practical domain is all real numbers from 4 to 9, inclusive.
The practical range is all real numbers from 49.6 to 111.6, inclusive.
These are the correct options.
Explanation:
Given function is f(t) = 12.4t
Let us assume that Nate works 'x' hours so 4<x<9
And multiplying the hours with his earnings we get the range.
4*12.40=49.6 and 9*12.40=111.6. Let the amount earned be represented by y
Hence, domain can be represented as 4<x<9 and range can be represented as 49.6 < y < 111.6
y=15
5y-20=2y+25 move terms
5y-2y = 25+20 calculate like terms
3y=45 divide both sides by 3
