Find the equation and solve it.

1 answer:

5 0

4(3x + 1)= 76
*There are 4 sides to a square and they are all equal in length, so you would mulitply 3x +1 by 4
*The total perimeter is 76
*Distribute the 4 into the equation

12x + 4=76
*subtract 4 on both sides

12x=72
*divide 12 on both sides

x=6
*Plug 6 in for x in the equation

3(6) +1
*this means that each side of the square would be 19 meters
*If you want to check to make sure you solved for x correctly, just plug it into the equation[4(3x + 1)]

Hope this helps!

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.

Mrs. Baxter needs to buy new headphones for all 559 students. If each headphone costs 15 dollars, how much will it cost Mrs. Bax

vaieri [72.5K]

Answer:

so this is a pretty simple question 559x15=x

Step-by-step explanation:

what we can do to make this equation more easy is do 559x10= 5590

and then just multiply 559x5=2795

2795+5590=8385

so in conclusion he needs $8385

Bingel [31]

Answer: (d). Area = 6.8 × 10^3 m^2 (to 2 significant figure)

Step-by-step explanation:

The area to find rectangular is:

Area = length × breadth

Area = 32.30 × 210

Area = 6783 m^2

Area = 6.8 × 10^3 m^2 (to 2 significant figure)
