<span>Hello : let
A(-3,7) B(3,3)
the slope is : (YB - YA)/(XB -XA)
(3-7)/(3+3) = -2/3
an equation is : y=ax+b a is a slope</span>
y = (-2/3)x +b
the line through point B (3,3) :
3 = (-2/3)(3)+b<span>
<span>b =5
the equation is : y =(-2/3)x+5</span></span>

Answer:
x = 5m/s
Step-by-step explanation:
Distance flying out = 12 km (headwind)
Distance flying back = 12 km (tailwind)
total distance = 12 + 12 =24 km
wind speed = 1km/h
speed going out (with headwind) = (x - 1) km/h
speed coming back (with tailwind) = (x + 1) km/h
Time taken to go out = distance going out / speed going out
= 12 / (x-1)
Time taken to come back = distance coming back / speed coming back
= 12 / (x+1)
total time = time taken to go out + time taken to come back
5 =[ 12/(x-1) ] + [ 12/(x-1)]
expanding this, we will get
5x² - 24x - 5 = 0
solving quadratic equation, we will get
x = -1/5 (impossible because speed cannot be negative)
or
x = 5 (answer)
Multiply the money earned on the first day ($35.20) by 1/4.
= 35.20 * 1/4
multiply numerators
= (35.20 * 1)/4
=35.20/4
divide
= $8.80
ANSWER: $8.80 was used to buy more supplies

Answer:
You need to write an equation to find the answer to this:
h = hours
48 + 13.5h = 112.50 -First you need to subtract 48 from both sides
48 - 48 + 13.5h = 112.50 - 48
13.5h = 64.5 -Now divide both sides by 13.5
13.5h / 13.5 = 64.5 / 13.5
h = 4.77777778
However, I would just round to 5.
I hope this helps!
