1 is the additive identity of any real number True or False

Mathematics

1 answer:

sergey [27]3 years ago

8 0

Answer:

False

Step-by-step explanation:

It is False. 1 is the identity element for multiplication, because if you multiply any number by 1, the number doesn’t change. Identity elements are specific to each operation (addition, multiplication, etc.). So while 1 is the identity element for multiplication, it is NOT the identity element for addition.

The treasure box in Tammy's room is in the shape of a rectangular prism. The height is 7 inches, the lenght is 12 inches and wit

Sliva [168]

Answer:

336in^3

Step-by-step explanation:

The volume of a rectangulur prism can be found by multiplying the length of the box with its height and width.

Thus, we can find the volume using the solution below:

v=l*w*h

l = 12in

h = 7in

w = 4in

12*7*4 = 336in^3

hich statement best describes the domain and range of p(x) = 6–x and q(x) = 6x? p(x) and q(x) have the same domain and the same

Sati [7]

Answer:

$p(x)$ and $q(x)$ have the same domain and the same range.

Step-by-step explanation:

$p(x) = 6-x$ and

$q(x) = 6x$

First of all, let us have a look at the definition of domain and range.

Domain of a function $y =f(x)$ is the set of input value i.e. the value of $x$ for which the function $f(x)$ is defined.

Range of a function $y =f(x)$ is the set of output value i.e. the value of $y$ or $f(x)$ for the values of $x$ in the domain.

Now, let us consider the given functions one by one:

$p(x) = 6-x$

Let us sketch the graph of given function.

Please find attached graph.

There are no values of $x$ for which p(x) is not defined so domain is All real numbers.

So, domain is $(-\infty, \infty)$ or $x\in R$

Its range is also All Real Numbers

So, Range is $(-\infty, \infty)$ or $x\in R$

$q(x) = 6x$

Let us sketch the graph of given function.

Please find attached graph.

There are no values of $x$ for which $q(x)$ is not defined so domain is All real numbers.

So, domain is $(-\infty, \infty)$ or $x\in R$

Its range is also All Real Numbers

So, Range is $(-\infty, \infty)$ or $x\in R$

Hence, the correct answer is:

$p(x)$ and $q(x)$ have the same domain and the same range.

<span>A) Participation in the spring league is increasing more than twice as fast as participation in the fall league.

this is what i believe is the answer. Parcipatation raises by 11 for spring and 3 for fall, and 11 is more than twice 3. i hope this helps! :D</span>

Solve the system<br> y= 3x+7<br> y=2x-3

notka56 [123]

Answer:(-10,-23)

Step-by-step explanation:

Okay....the easiest way to answer this would be either elimination or graphing. However, you could also use substitution.

Right now, I'll show how to use it by elimination.

First this is to convert both equations to standard form (x+y=__)

What we'll do for the first one is add 3x to each side. We end up with this:

-3x+y=7

Then subtract 2x from the other one. Ending up with:

-2x+y=-3

Now, we eliminate the y by subtracting.

-3x+y=7

(-) -2x+y=-3

___________

-x =10

x = -10

Now, plug in the x to one of the equations.

y=2(-10)-3

y=-20-3

y=-23

Make sure to check your answer by plugging both into the equations.

X=-10

Y=-23

You download music for 1.99 per song(s) and spend a total of 15.92

ad-work [718]

If you paid a total of 15.92 and also paid 1.99 per song, then you must divide the total by the cost per song.
As such 15.92/1.99 = 8 songs. :)
