Answer:
d
Step-by-step explanation:
it has the same slope but not the same y-int
(3,9)(5,15)
slope = (15 - 9) / (5 - 3) = 6/2 = 3
y = mx + b
slope(m) = 3
(3,9)...x = 3 and y = 9
sub and find b, the y int
9 = 3(3) + b
9 = 9 + b
9 - 9 = b
0 = b
so ur equation is : y = 3x + 0....can be written as y = 3x.
after 12 months...
y = 3x...x = 12
y = 3(12)
y = 36 inches
It is 4/3. the quantity of 4 over 3
X+6/3 - x+2/3= x+6-x-2/3 = 4/3.
24000 + 3000x = 30000 + 2400x
3000x - 2400x = 30,000 - 24,000
600x = 6000
x = 6000/600
x = 10 years
So basically isolate the X
4x>32
Divide both sides by 4
X> 8
