Function rule: a = 20w + 115
Slope: 20
Initial value: 115
------------------------------------------
We start with $115 in the account. This is the initial value. Each week we add on $20.
So we add $20 for 1 week
We add 2*20 = $40 for 2 weeks
We add 3*20 = $60 for 3 weeks
etc etc
In general, we add 20*w dollars for w weeks onto 115 to get a = 20w+115
The slope is 20 because this is the rate of change, ie how fast the account grows. It grows 20 dollars per week.
Since Sydney has planted 5/9 of her flowers and there were 63 flowers that are left unplanted, the first thing we are going to determine is the number of flowers that were planted. To do this, we just have to do the cross multiplication process.
So 5/9 x ?/63 = 35. Therefore, the number of plants planted were 35. To start, Sydney has a total of 100 flowers to be planted. That would be 35 + 65 is 100.
Yes it is correct because you would multiply 30 by 7 which equals 210 + the extra 20 dollars / 50 dollars (idk).. she will have more than enough though
... there is no math problem here
Answer:
The average rate of change between -1 and 2 is 1.
Step-by-step explanation:
To get this, use the two ordered pairs (-1, 5) and (2, 8). Now use the slope formula to find the rate of change.
m(slope) = (y2 - y1)/(x2 - x1)
m = (8 - 5)/(2 - -1)
m = 3/3
m = 1
