(x-4)/(2x+1)-3 can you help me with this question
lilavasa [31]

Answer:

\frac{(x - 4)}{(2x + 1)} - 3 = \frac{-7x- 7}{3x + 1}

Step-by-step explanation:

Given

\frac{(x - 4)}{(2x + 1)} - 3

Required

Solve

Express 3 as a fraction

\frac{(x - 4)}{(2x + 1)} - \frac{3}{1}

Take LCM

\frac{x - 4 - 3(2x + 1)}{3x + 1}

\frac{x - 4 - 6x - 3}{3x + 1}

Collect Like Terms

\frac{x - 6x- 4  - 3}{3x + 1}

Simplify like terms

\frac{-7x- 7}{3x + 1}

Hence:

\frac{(x - 4)}{(2x + 1)} - 3 = \frac{-7x- 7}{3x + 1}

The equation can also be seen as y = 0.25x + 0.

There is no x-intercept in the equation. This means that Aster has no base pay, or no starting pay. So all of her earnings only depend on x amount of car sales.

timurjin [86]

The interest on the investment when the interest rate is 9% is; $101.25.

<h3>What is the interest when the interest rate is 9%?</h3>

It follows from the task content that the interest on an investment varies directly as the rate of interest.

Hence, it follows from proportion that the interest when the interest rate is; 9% can be calculated as follows;

= 9 ×45/4

= $101.25

Ultimately, the interest on the investment evaluated by means of proportional reasoning is therefore; $101.25.
