Answer:
2nd option.
Step-by-step explanation:
3(8 - 4x) < 6(x - 5)
24 - 12x < 6x - 30
-12x - 6x < -30 - 24
-18x < -54
x > 3

just trust me, idk how to explain it
Answer:
y = ( x-2)(x+7)
Step-by-step explanation:
y = x^2 + 5x - 14
What 2 numbers multiply to -14 and add to 5
-2 * 7 = -14
-2+7 = 5
y = ( x-2)(x+7)
19000 =12k +c
26000= 9k +c
subtract the first from the second
7000= -3k --> k = -7000/3
sub that into one of the other eqns
say the first , so c= 19000-12k = 47000
