8^x=2 write down the value of x

e-lub [12.9K]

Answer:

x = $\frac{1}{3}$

Step-by-step explanation:

Using the rule of exponents

$a^m^{n}$ = $a^{mn}$

Note that 8 = 2³ and 2 = $2^{1}$ , then

$(2^3)^{x}$ = $2^{1}$ , that is

$2^{3x}$ = $2^{1}$

Since the bases on both sides are equal, equate the exponents

3x = 1 ( divide both sides by 3 )

x = $\frac{1}{3}$

A company has determined that the number of items it sells varies inversely as the price of the item. If 20,000 items can be sol

mestny [16]

Let N be the number of items sold and p the price.
Since the variation is inverse, then the relation between N and p is:
$N=k\dfrac{1}{p}$
For N=20000 and p = $9.5, we get the formula:
$20000=k\dfrac{1}{9.5}\\p=20000\times9.5=190000$
If p = 8.75, then the number of items sold can be computed using the formula:
$N= 190000\dfrac{1}{8.75}=21714 \text{ total items}$

Solve the following system of equations using the elimination method. 5x + y = 9 –10x + 7y = 18 Question 6 options: A) (2,–6) B)

Leya [2.2K]

Answer:

Step-by-step explanation:

5x + y = 9

-10x + 7y = 18

10x + 2y = 18

-10x + 7y = 18

9y = 36

y = 4

5x + 4 = 9

5x = 5

x = 1

Solve the equation of the function for n.

a(n) = 3n - 20

a = 3n - 20

a + 20 = 3n

(a + 20)/3 = n

n = (a + 20)/3

n(a) = (a + 20)/3
