Answer:
250 ft/mile
Step-by-step explanation:
.. ......................
1.5x + 0.2y = 2.68....multiply by 0.3
1.6x + 0.3y = 2.98...multiply by - 0.2
------------------------
0.45x + 0.06y = 0.804 (result of multiplying by 0.3)
- 0.32x - 0.06y = - 0.596 (result of multiplying by - 0.2)
----------------------add
0.13x = 0.208
x = 0.208/0.13
x = 1.6
1.5x + 0.2y = 2.68
1.5(1.6) + 0.2y = 2.68
2.4 + 0.2y = 2.68
0.2y = 2.68 - 2.4
0.2y = 0.28
y = 0.28/0.2
y = 1.4
solution (they intersect at) (1.6,1.4)
Answer:
x = 0, 4, -2
Step-by-step explanation:
f (x) = 3x (x – 4) (x + 2)
0= 3x (x – 4) (x + 2)
3x = 0, x-4 =0 , x+2 = 0
x = 0, 4, -2
