Answer:
a(n) = 10n-1 (the second one)
Step-by-step explanation:
we use formula
a(n) = a +(n-1)d (a= the first number in the, n=the times we need, d= difference)
a=9
d=9-19=10
a(n) = 9 +(n-1)10
a(n) = 9 +10n-10
a(n) = 10n-1 (the second one)

Answer:
Ali runs 1 minutes per 10 calories burned
Slope: 10
Step-by-step explanation:
Slope = y/x = 100/10 = 10
Try this solution, note, the suggested option is not the shortest way.
We have that
[(4x+2)/(x+5)]-[(3x+1)/(x+5)]
<span>They have common denominators, so just add the numerators like normal fractions:</span>
=[(4x+2)-(3x+1)]/(x+5)
=[(4x+2-3x-1)]/(x+5)
=[(x+1)]/(x+5)
the answer is
(x+1)/(x+5)
