Ax+by=c is form
start from y=mx+b form
we know that b=y intercept or b in (0,b) when x=0
so
we got (0,-4)
so b=-4
y=mx-4
find m
(5,1)
x=5 and y=1 is true
1=5m-4
add 4 both sides
5=5m
divide 5
1=m
slope is 1
y=1x-4
y=x-4
convert
minus x both sides
-x+y=-4
times -1
x-y=4
(2308*10)/100=230.3 so he would have to pay 230 hundos (and 30 singles)
Answer:
17=3x+2 x=5
Step-by-step explanation:
3x+2=17
3x=17-2
x=15/3
x=5

Answer: The distance of Observer A from the radio antenna is what fraction of the distance of Observer B from the radio antenna?
It is 1/4.
Step-by-step explanation:
We know that the intensity of electromagnetic waves decreases with the radius squared, this means that we can write a simple relation as:
Intensity(r) = A/r^2
Observer A measures 16 the intensity of observer B.
if Ia is the intensity that observer A measures and Ib is the intensity that observer B measures, we have that:
Ia = 16Ib
A/(ra)^2 = 16*A/(rb)^2
1/(ra)^2 = 16/(rb)^2
rb^2 = 16*ra^2
and we know that 16 = 4*4 = 4^2
rb^2 = (4*ra)^2
then rb = 4*ra
this means that the distance between observer B and the antenna is equal to 4 times the distance between observer A and the antenna.
The fraction is ra = rb/4
The distance of
Observer A from the radio antenna is what fraction of the distance of Observer B from the radio antenna?
It is 1/4.
