Start by dividing both sides by 2 to get log(x)= \frac{1}{2}log(64).  Doing the math on the right, keeping in mind that logs have an unwritten base of 10, gives us log_{10} (x)=.903089987.  Rewriting this in exponential form is 10^{.903089987}=x.  That means that x = 8.  Not negative, only positive.

Find the value of x so that the function has the given value.
nataly862011 [7]

For h(x) = -7x + 10, x =1

For r(x) = 4/5x+ 7 , x = -15

Step-by-step explanation:

in order to find the value of x on which the functions will have given values, we will put the functions equal to the given values

So,

<u>h(x) = -7x + 10; h(x) = 3</u>

h(x) = -7x+10\\3 = -7x+10\\3-10 = -7x+10-10\\-7 = -7x

Dividing both sides by -7

\frac{-7x}{-7} = \frac{-7}{-7}\\x = 1

<u>r(x) =  4/5x+7; r(x) = -5</u>

r(x) = \frac{4}{5}x +7\\-5 = \frac{4}{5}x +7\\-5-7 = \frac{4}{5}x\\-12 = \frac{4}{5}x\\x = -12 * \frac{5}{4}\\x = -15

<u></u>

Hunter-Best [27]

Answer:

12 ≠ 14

Step-by-step explanation:

(4+8)=2+(6x2)

12 = 2 + 12

12 ≠ 14.

So the equation is false.
