Answer:
you want to isolat U on one side, so subtract 9/-4 from both sides to end up with (9/-4) - 9 = u, then solve. (9/-4)-9 = -11.25, so -11.25 = u
The ANSWER for this question is D.14
X + y ≥ 10
y ≥ -x + 10 . ← Slope Intercept Form
Slope = -1
y-intercept = 10
The question is asking to state how can you tell when a pattern shows counting on by tens, when you subtract the two number and there difference would be 10, that would be and an indicator. Hope i helped!
