Answer:
The answer to your question is: y = -1/9 x - 40/9
Step-by-step explanation:
Data
A (-4 , -4)
B (5, -5)
Formula
m = (y2 - y1) / (x2 - x1)
y = mx + b
(y - y1) = m(x - x1=
Process
m = (-5 + 4) / (5 + 4)
m = -1 / 9
( y +4) = -1/9 (x + 4)
y + 4 = -1/9 x - 4/9
y = -1/9 x - 4/9 - 4
y = -1/9 x - 4/9 - 36/9
y = -1/9 x - 40/9
Let x = speed of the first car
the second car is 12 km slower so the seconds car speed is x-12
they each drove 2 hours so 1st car = 2x
2nd car = 2(x-12)
they drove 360 km
so you have 2x + 2(x-12) = 360
solve for x
2x+2(x-12) = 360
2x + 2x-24 = 360
4x-24 = 360
4x = 384
x = 384/4
x = 96
1st car drove at 96 km per hour
slower car drove at 96-12 = 84 km per hour
Ok so for number 2. There are 101,934 people living in the city and there are 29,382 people in the suburbs. They want the total amount of people living in the whole city. The problem would be 101,934+29,382= and it would equal B. <span>131316. I hope that this helped you.</span><span />
Step-by-step explanation:
yes, the 2 events are entirely independent
neither one influences the other.
3 3/4 =3.75
20.25 divide 3.75 = 5.4
one pound of candy costs 5.40
