Answer:
0 =-4.5X +49.5
x = 11
Step-by-step explanation:
x1 y1 x2 y2
1 45 3 36
(Y2-Y1) (36)-(45)= -9 ΔY -9
(X2-X1) (3)-(1)= 2 ΔX 2
slope= -4 1/2
B= 49 1/2
Y =-4.5X +49.5
Answer:
Rate for 100 miles = $ 6 / miles
Rate for 250 miles = $ 3.3 / miles
Step-by-step explanation:
Given that cost for covering 100 miles by flight is $600.
As rate is the cost of covering unit distance (in miles).
So, the rate to cover 100 miles by flight = $ 600/ 100 miles = $ 6 /miles.
Similarly, the cost of covering 250 miles by flight is $825.
So, the rate to cover 250 miles by flight = $ 825/ 250 miles = $ 3.3 /miles.
The compound interest formula is
FV=P(1+(r/n))^n*t
FV= future value
P= principal or amount of $ deposited
r= annual interest rate in decimal form
n= number of times compounded per year
t= time in years
Therefore 8000(1+(.12/12))^12*7 which equals $18453.78
Step-by-step explanation:
- 5x+12=6x+7 (opposite sides of a parallelogram are equal)
- 12=x+7 (subtract 5x from both sides)
- x=5 (subtract 7 from both sides)
- Now put x in any of the equations-- 5(5)+12=37 or 6(5) +7=37
