Answer:

a)

a=\frac{1}{180x^2}

b)

b=-4+\frac{28}{x}

c)

c=\frac{22x}{x-2}

Step-by-step explanation:

a)

(xa)6=\frac{1}{30x}

To find the value of a, we make a the subject of the equation, therefore cross multiplying to get:

1=180x^2a\\a=\frac{1}{180x^2}

b)

-4(x-7) = xb

Making b the subject of formula in the equation:

-4x+28=xb\\b=\frac{-4x+28}{x}\\ b=-4+\frac{28}{x}

c)

(x-2)c = 22x\\

Making c the subject of the equation:

(x-2)c = 22x\\c=\frac{22x}{x-2}

How many Solutions does 6 + x/5 = x/5 - 5 - 3x/10 have?
klasskru [66]

9514 1404 393

Answer:

  1 solution (x = -36 2/3)

Step-by-step explanation:

  6 + x/5 = x/5 - 5 - 3x/10 . . . . . . . given

  60 +2x = 2x -50 -3x . . . . . . . . . multiply by 10

  3x = -110 . . . . . . . . . . . . . . . .  add x-60 to both sides

  x = -110/3 = -36 2/3 . . . . . .divide by the coefficient of x

There is one solution to the equation.

_____

<em>Additional comment</em>

The coefficient of x on the left side of the equation is not equal to the coefficient of x on the right side. When that is the case, the equation will have one solution.

When the coefficients are equal, there will be no solutions if the constants are different, and there will be infinite solutions if the constants are the same.

Suppose f(x)=x^2 what is the graph of g(x)=f(2x)
Naddika [18.5K]

Answer:

Since g(x) = f(2x), this means we substitute 2x in place of x for f(x):

g(x) = f(2x) = (2x)² = 4x²

Graphing this, the parabola is not moved from the parent graph f(x) = x², but the graph is compressed horizontally by a factor of 4.Step-by-step explanation:
