17x= 13 and 8 are both y's so you combine them by subtracting 13 from both sides and then you have 17x=-5y
Answer:1.2r
Step-by-step explanation:
Just transpose the 5 to the right side of 18 so it will look like this, /x/ = 18 - 5
Then get the difference and it would be 13. So to check this out if it is correct, substitute x for the value of 13 and it will look like this.
13 + 5 = 18
I hope my answer helped you.
Maddie :
(1,100),(2,80)
slope (rate of change) = (80 - 100) / (2 - 1) = -20/1 = -20
Caitlin :
y = -18x + 120......slope (rate of change) = -18
To determine which rate of change is greater, take the absolute value of the slopes.
Maddy : | -20 | = 20
Caitlin : | -18 | = 18
the greater rate of change is the one with the larger absolute value....so that would be Maddy...function 1 shows a greater rate of change because Maddie spends 20 each month and Caitlin spends 18 each month
