Answer:
(12.2,-6.4)
Step-by-step explanation:
The results from Desmos are as shown.
The displayed values are (12.294, -6.353)
Y= -10x + 190
In using a linear function, follow the pattern y=mx + b.
In this scenario, the m (which represents slope) is -10 since $10 is taken away every time. The b(which represents y-int) is 190 because you start with 190 (x=0)
It would take her about 15 seconds
Multiply the first digit by 3 then subtract the answer by 2. Rule: x 3 - 2
