1,000 because kilometers is 1,000 is how many is for 2 but for one it's 500
Answer:
A. Y-68=-5(x-14)
Step-by-step explanation:
Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number of days that have passed. write an equation for the situation
We find the equation using the point slope equation of a line. This is given as:
y - y1 = m(x-x1)
The slope intercept form will be
y = -5x + b
since the amount decreases by $5 per day...
Our slope is -5 so m=-5
We have a point (x1,y1) = (14, 68)
Hence, we have:
y-68 = -5(x-14)
Option A is correct
Answer:
If each book cost $20.45 then you times it by 21 and the answer you would get is 429.45
Step-by-step explanation:
im 99% that its correct
15$ I believe, as we can disregard the two original books (they have been payed for) leaving her to buy 1 book and having seven dollars, however if she needs $8 more you simply need to add 8+7.
Slope = difference in y / difference in x
slope = 5 - 0 / 4 - 10
slope = 5 / -6
slope = -.83333
