(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:

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

Which of the following represents the graph of f(x) = one−half to the power of x?

puteri [66]

f(x) = $\frac{1}{2}^x$

In this exponential function , the base is $\frac{1}{2}$

if base is less than 1 then it a decreasing function

We can verify it using a table

We plug in some x and values and find out f(x) to get point for the graph

x -----> f(x)

-1 -----> 2

0 ------> 1

1 -------> 0.5

The table is same as the points in first graph.

So first graph represents the graph of f(x) = $\frac{1}{2}^x$
