I'm assuming that you mean

because if you meant

then u would simplify and you couldn't make it the subject.
Under this assumption, we start with

We multiply both sides by 

We expand the left hand side:

We move all terms involving u to the left and all terms not involving u to the right:

We factor u on the left hand side:

We divide both sides by 

y intercept = 1/2
<u>Step-by-step explanation:</u>
Step 1:
Formula y=mx+b in Slope Intercept form( whereas m= slope of the given equation, b= y intercept)
Step 2:
Comparing the given equation y = -3x + 1/2
we get m=-3(Slope) and y-intercept b=1/2
Answer:
Input: 0, 2, 4
Output: 3, -1, 1
Step-by-step explanation:
0-3= -3
2-3= -1
4-3= 1
H=(√3)*a/2 = 41.2
So, a=2*41.2/√3=47.6
Answer:
2160
Step-by-step explanation:
Distance covered per day =540miles
Number of days travelled = 4 days
Therefore,the mil we s travelled altogether= 540×4= 2160
