Question

please help for a medal

Answer 1

Morgan and Leigh spend a certain amount of money from their money box each month to buy plants.

The table shows the relationship between the amount of money (y) remaining in Morgan's money box and the number of months (x):
Function 1Number of Months
(x) Amount Remaining (in dollars)
(y)
1 50
2 40
3 30
4 20


The equation shows the relationship between the amount of money (y) remaining in Leigh's money box and the number of months (x):

Function 2:
y = −9x + 60

Which statement explains which function shows a greater rate of change?

Function 1 shows a greater rate of change, because Morgan spends $10 each month and Leigh spends $9 each month. Function 1 shows a greater rate of change, because Morgan spends $10 each month and Leigh spends $60 each month. Function 2 shows a greater rate of change, because Morgan spends $10 each month and Leigh spends $60 each month. Function 2 shows a greater rate of change, because Morgan spends $50 each month and Leigh spends −$9 each month.

Answer 2

the rate of change for 1st function is -10 and rate of change of 2nd function is -9. Use the slope formula to find the slope of 1st function

Answer 3

i have no clue what a slope formula is...

Answer 4

so Function 1 shows a greater rate of change, because Morgan spends $10 a month and Leigh spends $9 a month

Answer 5

the slope formula is
\[m=(y_1-y_2)/(x_1-x_2)\]

Answer 6

where y1, y2, x1 and x2 are coordinates of two points, which belong to the function

Answer 7

function 2

Answer 8

Function 1 shows a greater rate of change, because Morgan spends $10 each month and Leigh spends $9 each month.

Answer 9

ohh i see ok
