Evaluate this expression for

x= 3.1 [Given]

Now,

7x - 5

<em>Putting</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em> </em>

⇒<em> </em>7 × 3.1 - 5

⇒ 21.7 - 5

⇒ 16.7

The value of the expression is 16.7

Answer:

Answer is 16.7

Step-by-step explanation:

$Given \: expression \: is \: \: 7x - 5 \\ tofind \: the \: value \: of \: the \: expression \: \\ when \: x = 3.1 \\ on \: substituting \: x = 3.1 \: in \: the \: given \: expression \\ 7x - 5 = 7(3.1) - 5 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 21.7 - 5 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 16.7$

Use a table of values with at least 5 values to graph the following function:

34kurt

The given expression :

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

For coordinates:

put x = 0 then :

$\begin{gathered} y=(\frac{1}{2})^0 \\ y=1 \end{gathered}$

Coordinate : (x, y) = (0, 1)

Put x= 1 and simplify :

$\begin{gathered} y=(\frac{1}{2})^1 \\ y=\frac{1}{2} \\ y=0.5 \end{gathered}$

Coordinate : (x, y) = ( 1, 0.5)

Put x = (-2) and simplify :

$\begin{gathered} y=(\frac{1}{2})^{-2} \\ y=\frac{1^{-2}}{2^{-2}} \\ y=\frac{2^2}{1^2} \\ y=2^2 \\ y=4 \end{gathered}$

Coordinate : (x, y) = ( -2, 4)

Put x = (-3) and simplify :

$\begin{gathered} y=(\frac{1}{2})^{-3} \\ y=\frac{1^{-3}}{2^{-3}} \\ y=\frac{2^3}{1^3} \\ y=2^3 \\ y=8 \end{gathered}$

Coordinate : (x, y) = (-3, 8)

Substitute x = (-1) and simplify :

$\begin{gathered} y=(\frac{1}{2})^x \\ y=(\frac{1}{2})^{-1} \\ y=\frac{1^{-1}}{2^{-1}} \\ y=\frac{2}{1} \\ y=2 \end{gathered}$

Coordinate : (x, y) = ( -1, 2)

So, the coordinates are :

The graph is :

Solve for x.<br><br> 4x + 6 = 38<br><br> What is the answer?

sertanlavr [38]

Answer:

x = 8

Step-by-step explanation:

We solve the equation:

4x + 6 = 38

4x = 38 - 6

4x = 32

x = 32 ÷ 4

x = 8
