Answer:
answer 16 teacher gets 8.43
answer for pet store: 263.44
Step-by-step explanation:
take 3.25 multiply by 3.56 now you get 11.57
20 - 11.57 is 8.43
pet store part time:
take 10.24 multiply it by 22.25 = 227.84
take 1.60 multiply it by 22.25 = 35.6
add 227.84 and 35.6 you get 263.44
Answer:
We conclude that the person is saving $60 dollars per week.
Hence, option C is true.
Step-by-step explanation:
Given the table chart
Week Saving Money
2 60
4 120
6 180
8 240
We know to determine the slope to find the rate of change.
Taking the points (2, 60) and (4, 120)
Rate of change = Slope = [y₂ - y₁] / [x₂ - x₁]
= [120 - 60] / [4 - 2]
= 60 / 2
= $30 dollars per week
Now, taking the points (4, 120) and (6, 180)
Rate of change = Slope = [180 - 120] / [6 - 4]
= [60] / [2]
= $30 dollars per week
Now, taking the points (6, 180) and (8, 240)
Rate of change = Slope = [240 - 180] / [8 - 6]
= [60] / [2]
= $30 dollars per week
- This concludes that the rate of change is contant i.e. $30 dollars per week
Therefore, we conclude that the person is saving $60 dollars per week.
Hence, option C is true.
True or false.. it would be False
The generic equation of the line is:
y-yo = m (x-xo)
Where,
m = (y2-y1) / (x2-x1)
m = (0-1) / (4-3)
m = (- 1) / (1)
m = -1
We choose an ordered pair:
(xo, yo) = (4, 0)
Substituting:
y-0 = -1 (x-4)
y = -x + 4
Answer:
y = -x + 4
