Answer:
After 5 weeks.
Step-by-step explanation:
Westley starts with $85 and saves $5 per week. So:

Buttercup starts with $10 and saves $20 per week. So:

When they have the same amount of money, the two equations will be equal to each other. Therefore:

Solve for x. Subtract 10 from both sides:

Subtract 5x from both sides:

Divide both sides by 15:

Westley and Buttercup will have the same amount of money after 5 weeks.
<span>f(k) = k2 + 2k + 1 = (k+1)^2
The range is what the function gives to you f(k)=25=5^2 or (-5)^2
f(k)=64=8^2 or (-8)^2
You need to find the k values for these boundary values to find the domain.
Good luck :)</span>
Answer:
Juan rode more slowly, Rita's graph is much steaper than Juan's. This means that she went faster and in less time. Juan took longer time and went on a slower pace. That's why I chose Juan.
