Answer:
u ≤ 4
Step-by-step explanation:
The given inequality
15 ≤ 39 - 6u
Subtract 39 from both sides, we get
15 - 39 ≤ 39 - 6u - 39
-24 ≤ -6u
Dividing both sides by -6, we get
4 ≥ u [Remember, when we divide by negative, the direction of
the inequality changes]
Which is u ≤ 4.
Thank you.

Step-by-step explanation:
The options can be resumed to the 2nd and 3rd options. If the x-values come first when representing the pair of coordinates, so they will look like (1, y), (2, y), (3, y), and (4, y).
Now we only need to calculate the y-values.
y(1)=14×1+8 ⇔ y(1)=14+8 ⇔ y(1)=22
From only this result we know that the correct option is the third, starting with (1,22).
Only for verification, below are the other y-values' calculations.
y(2)=14×2+8 ⇔ y(2)=36
y(3)=14×3+8 ⇔ y(3)=50
y(4)=14×4+8 ⇔ y(4)=64
<span>87 less than the quotient of an unknown number and 43 is -75
Converting that to mathematical equation:
87 - (x / 43) = -75
Evaluating the equation, we can the value of x.
87 - (x/43) = -75
-x/43 = -75 - 87
-x/43 = -162
-x = -6966
x = 6966</span>
