Solve: S = n/2 (a+b) for b

Mathematics
1 answer:
IgorC [24]4 years ago

Answer:

b = -n/(2-S) -a

Step-by-step explanation:

S = n/2 (a+b)

divide both sides by (a+b)

S/(a+b) = n/2

flip the equation on the left (it is the same equation just negative)

-(a+b)/-S = n/2

divide both sides by -S

-a-b = n/(2-S)

add a to both sides

-b = n/(2-S) +a

flip the sign (multiply/divide by -1)

b = -n/(2-S) -a

If 2x^2+2x=12, what is x?
Rainbow [258]

Answer:

x= 2

x= -3

Step-by-step explanation:

<u>Solving as normal quadratic equation:</u>

  • 2x^2+2x=12
  • x^2 +x = 6
  • x^2 + x - 6= 0
  • x = (-1 ± √(1+4*1*6)/2
  • x = ( - 1 ± √25)/2
  • x = (-1 ± 5)/2
  • x= 2
  • x= -3

The equation of a line is y= -1/2x - 2. What is the equation of the line that is perpendicular to the first line and passes thro
Fed [463]
If two line are perpendicular. The multiply of their slopes are equal to -1. 
First line's slope is: -1/2x because if the line equation is form of y=ax+b a is slope. 
Let say second line's slope is m
m.-1/2=-1  so m=2 
y=ax+b is general form of linear function/equation. (a=slope)
y=2x+b 
If this line passes through the point (2,-2),if we write -2 to y and 2 to x, the equation becomes true. 
-2=4+b
b=-6 
Thus, 
y=2x-6 is true answer.
