Step-by-step explanation:
1 week = 7 days
given 7 days = 14 hours of practice
and let x be the number of hours spent on practicing and y the number of days.
from the above expression we can have the equation,
using the equation when y = 10,
A) Variables:
X = number of weeks she puts money into the account.
Y = total amount in account after x weeks.
B) m would be the amount she puts in per week, b is the starting amount she has in the account
Y = 5x + 40
C) replace x with the x values in the cart and solve for y:
O : y = 40. Coordinates (0,40)
1: Y = 45. (1,45)
2: 50, (2,50)
3: 55, (3,55)
4: 60, (4,60)
D) make the graph using the above points
E) y intercept is when x is 0, which is 40. This was the starting value of how much money was saved.
Answer:
48
Step-by-step explanation:
The maximum third side length of a triangle with two sides 5 and 19 is 5+19-1=23. Therefore, the maximum perimeter of a triangle with the two side lengths given is 5+19+23=47.
The smallest whole number larger than this is 48.
