Answer:

x = 10

Step-by-step explanation:

1/3 (2x - 8)=4.

Multiply each side by 3

1/3 *3(2x - 8)=4.*3

2x-8 = 12

Add 8 to each side

2x-8+8 =12+8

2x = 20

Divide each side by 2

2x/2= 20/2

x = 10

A right rectangular prism's edge lengths are 14 inches, 6 inches, and 3 1/3 inches. How many unit cubes with edge lengths of 2/5
DochEvi [55]

ANSWER

4375 unit cubes

EXPLANATION

The volume of a right rectangular prism is given by;

V=lbh

We substitute the given dimension to obtain,

V=14 \times 6 \times  \frac{10}{3}  = 280i {n}^{3}

The volume of the unit cube with edge lengths

\frac{2}{5}

is

(\frac{2}{5})^{3}  =  \frac{8}{125}  {in}^{3}

To find the number of unit cubes that can fit inside the prism, we divide the volume of the rectangular prism by the volume of the unit cube.

=  \frac{280}{ \frac{8}{125} }

= 4375

Find the domain for the rational function f of x equals quantity x plus 1 end quantity divided by quantity x minus 2 end quantit
Elena L [17]

Answer:

(- \infty, 2), (2, \infty)

Step-by-step explanation:

Given the function:

f(x) = \dfrac{x+1}{x-2}

To find:

Domain of the function.

Solution:

First of all, let us learn about definition of  domain of a function.

Domain of a function is the valid input values that can be provided to the function for which output is defined.

OR

Domain of a function f(x) are the values of x for which the output f(x) is a valid value.

i.e. The function does not tend to \infty or does not have \frac{0}0 form.

So, we will check for the values of x for which f(x) is not defined.

For value to tend to \infty, denominator will be 0.

x-2\neq 0 \\\Rightarrow x \neq 2

So, the domain can not have x = 2

Any other value of x does not have any undefined value for the function f(x).

Hence, the answer is:

\bold{(- \infty, 2), (2, \infty)}     [2 is not included in the domain].

Problem Page Alonzo will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $49.98
igomit [66]
You would start with the equation:Let m=number of miles

49.98+0.12m=35.98+0.17m

Then solve for m

You would then get

49.98+0.12m=35.98+0.17m
          -0.12m           -0.12m
 49.98=35.98+0.05m
-35.98  -35.98
14  = 0.05m
----    --------
0.05   0.05

280=m
