3|1/2x + 5| + 7 = 5
egoroff_w [7]

Answer:

<em>x is -34/3 and -26/3</em>

Step-by-step explanation:

Given the expression

3|1/2x+5| + 7 = 5

Removing the modulus sign

3(1/2x+5) + 7 = 5

Subtract 7 from both sides

3(1/2x+5) + 7 - 7= 5 - 7

3(1/2x+5) = -2

Open the bracket

3/2 x + 15 = -2

Subtract 15 from both sides

3/2 x + 15-15 = -2 - 15

3/2 x = -17

3x = -2*17

3x  = -34

x = -34/3

<em>Hence the value of x is -34/3</em>

<em>For the negative function:</em>

3(1/2x+5) + 7 = 5

Subtract 7 from both sides

3(-(1/2x+5)) + 7 - 7= 5 - 7

3(-1/2x-5) = -2

Open the bracket

-3/2 x - 15 = -2

Add 15 from both sides

3/2 x + 15-15 = -2 + 15

-3/2 x = 13

-3x = 2 * 13

-3x  =26

x = -26/3

<em>Hence the value of x is -26/3</em>

Write the equivalent logarithmic equation to 10^a = x+b
MA_775_DIABLO [31]

Answer:

The answer to your question is   log₁₀ x + b = a        

Step-by-step explanation:

General formula

                 Logarithmic function                Exponential function

                           log ₐ b = c                                  b^{c} = a

a = antilogaritm                                               c = exponent

b = base                                                          b = base

c = logaritm                                                     a = power

In your problem

10 = base

a = exponent

x + b = power

Exponential function              log₁₀ x + b = a
