Solve this problem T=u+v/2 solve for u
AfilCa [17]

Answer:

<h2>u = 2T - v</h2>

T =  \frac{u + v}{2}

Cross multiply

We have

2T = u + v

u + v = 2T

Move v to the right side of the equation to make u stand alone

We have the final answer as

<h3>u = 2T - v</h3>

Hope this helps you

You borrow $1900 to buy a refrigerator. The simple interest rate is 11%. You pay off the loan after 5 years. How much do you pay
leonid [27]
I = PRT is the formula to use for this.

I = (1900)(.11)(5)
I = 1045

1900 + 1045 = 2945

I need to pay $2945 for the refrigerator.

Which equation represents a nonlinear function?
Luden [163]
The correct answer is:  [A]:  " <span>x(y – 5) = 2 " .
</span>_____________________________________________________
Consider:
_____________________________________________________
Choice:  [A]:  " x(y–5) = 2 " ; 

Divide each side by "x" ;

" [x(y – 5)] / x  = 2/x " ; 

  →  y – 5 = 2/x  ;

Add "5" to each side of the equation:

y – 5 + 5 = 2/x + 5 ;

  →  y = 2/x + 5  ;  not a line;  since one cannot divide by "zero" ; there would be no "point" on the graph at "x = 0".  So, this answer choice:  [A] is correct.
_______________________________________________________
Choice [B]:
 
y -2x -18 = 0 

y - 2x = 18

y = 18 + 2x ;  y = 2x + 18 ; is a line.
_________________________________________________
Choice C)  3y + 12 - 6x = 5 ; 

3y = 5 - 12 + 6x ; 

3y = -7 + 6x ;  3y = 6x - 7 ;  y = 6x/3 - 7/3 ;  y = 2x - 7/3 ;  is a line.
_________________________________________________
Choice:  [D]:

2(y+x) = 0 ;

[2*(y+x)] / 2 = 0/2 ;  y + x = 0 ;  y = -x ;  is a line.
