Write y=-3/4x+3
Basile [38]

Answer:

In standard form the first equation is 3x + 4y = 12

Step-by-step explanation:

In order to find this, we need to solve for the constant and then eliminate the denominators.

y = -3/4x + 3

3/4x + y = 3

3x + 4y = 12

Simplify completely x^2+4x-45 / x^2+10x+9
S_A_V [24]

Answer: x - 5/x + 1

Step-by-step explanation:

This algebraic fraction

The task to be performed here is factorisation and simplification. Now going by the question,

x² + 4x - 45/x² + 10x + 9, the factorisation of

x² + 4x - 45 = x² + 9x - 5x - 45

= x(x + 9 ) - 5(x + 9 )

= ( x + 9 )(x - 5 ), don't forget this is the algebraic fraction's Numerator

The second part

x² + 10x + 9 = x² + x + 9x + 9

= x(x + 1) + 9( x + 1 )

= ( x + 9 )( x + 1 ), this is the algebraic denominator.

Now place the second expression which is the denominator under the first expression which is the numerator.

( x + 9 )( x - 5 )/( x + 9 )( x + 1 ).

You can see that, ( x + 9 )/( x + 9 ) divide each other , therefore therr then cancelled and left with

x - 5/x + 1

If f(x)= x^1/2 - x and g(x)= 2x^3 - x^1/2 - x, find f(x) - g(x)
Pavlova-9 [17]

Answer:

-2x^3+2x^{1/2}

Step-by-step explanation:

First, you have to substitute both functions into the equation to get:

f(x)-g(x) = (x^{1/2}-x) - (2x^3-x^{1/2}-x)

Then, you distribute the negative sign in front of g(x) to get:

= x^{1/2} - x -2x^3+x^{1/2}+x

And finally, you add/subtract the x's that have the same power to get:

=-2x^3+2x^{1/2}
