The difference between the coefficients 7 and 3 is 4, so one solution is
y = 1, x = -1.
Then the remaining solutions will be of the form
x = -7n-1
y = 3n+1
for some integer n.
_____
Some of the solutions are (for n=0, -1, -2, 1, 2)
(x, y) = (-1, 1), (6, -2), (13, -5), (-8, 4), (-15, 7)
Answer:
Step-by-step explanation:
1 hr=60 min
1 km=0.62137 miles
15 km/min=(15×60) km/hr=900 km/hr=(900×0.62137) miles /hr=559.233 miles/hr
Answer:
y= - frac4/7 x + frac9/7
Step-by-step explanation:
I=prt
9.90=p (.06)(3)
9.90=p(.18)
9.90/.18=p.18/.18
55=p
I put in $55 into the account when I opened it.
