Answer:
7. 37
8. 74
9. 402
10. 74
Step-by-step explanation:
You can simplify the expressions and then do the substitution of the variable value, or you can simply plug in the numbers and do the arithmetic. Either way takes about the same effort.
7. 3(5·4 -1) -4(3·4 -7) = 3·19 -4·5 = 57 -20 = 37
8. 3(5·4 -6) +4(20 -3·4) = 3·14 +4·8 = 74
9. 5(10r +3) -7r = 50r +15 -7r = 43r +15 = 43·9 +15 = 402
10. 4(5r -3) -2(6r -7) = 20r -12 -12r +14 = 8r +2 = 8·9 +2 = 74
ANSWER
(-∞,+∞)
EXPLANATION
The given polynomial function is:

The domain refers to all values of x that make the function defined.
Polynomial functions are defined for all real values of x
The domain is the set of all real numbers.
This is written in symbolic representation as
(-∞,+∞)
Answer:
The period is the change in x required for the function to return to the same value, changing in the same direction. The first two table entries are v(x) = 41.7 and 35.7. The next time that sequence appears is when x=44, so the period is ...
period = 44 -4 = 40 . . . seconds
__
The minimum table value is 20; the maximum is 44, so the midline of the function is their average:
midline = (20 +44)/2 = 32
__
The amplitude is the maximum deviation from the midline, so is ...
amplitude = 44 -32 = 12
