Graph the function g(x) = 1/3 - 4/3x

True [87]

  Solutions

g(x) = $\frac{1}{3}$ - $\frac{4}{3}$ x

  g(x) = - <span> $\frac{4}{3}$ x + $\frac{1}{3}$

x = -5

= </span>g(x) = - $\frac{4}{3}$ × (-5) + <span> $\frac{1}{3}$
</span>
= $\frac{20}{3}$ + <span> $\frac{1}{3}$
</span>
= $\frac{21}{3}$

= 7

(-5,7)

x = 7

  = g(x) = - $\frac{4}{3}$ × (7) +  <span> $\frac{1}{3}$
</span>
= $\frac{-28}{3}$ + <span> $\frac{1}{3}$
</span>
= $\frac{-27}{3}$ = -9

(-7,9)

x = (-7,9)   y = <span>(-5,7)</span>

Which of the following equations is equivalent to 2log4x − log49 = 2?

Masja [62]

Answer:

The value of x for given log equation is 17. 5

Step-by-step explanation:

Given as :

The log function is

2 log 4 x - log 49 = 2

Or, 2 log 4 x - log (7 × 7) = 2

Or, 2 log 4 x - log 7² = 2

<u>from Log property</u>

$Loga^{b}$ = b Log a

So, 2 log 4 x - 2 log 7 = 2

Taking 2 from Left hand side of equation

Or, 2 × (log 4 x - log 7) = 2

Or, (log 4 x - log 7) = $\dfrac{2}{2}$

Or, (log 4 x - log 7) = 1

<u>Again from Log property</u>

Log m - Log n = Log $\dfrac{m}{n}$

So, (log 4 x - log 7) = 1

Or, Log $\dfrac{4 x}{7}$ = 1

Now,<u> Taking anti Log , we get</u>

So, $\dfrac{4 x}{7}$ = antilog 1

i.e $\dfrac{4 x}{7}$ = $10^{1}$

Or, 4 × x = 10 × 7

∴ x = $\dfrac{70}{4}$

Or, x = 17.5

So, The value of x = 17.5

Hence, The value of x for given log equation is 17. 5 Answer
