What is x. PLS HELP PLEASE I WOULD REALLY APPRECIATE IT

ValentinkaMS [17]

Answer: The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try.

Step-by-step explanation:

To describe how we arrive at the answer, we are going to use the drawing i have attached to this response.

southwest of ship A is just a distance around the third quadrant (using the cardinal point) and it is below A

North of B is few distances ahead of ship B.

What is the inverse of the function H(x)=3/4x+12

Mrac [35]

Answer:

$h^{-1}$ (x) = $\frac{4x-48}{3}$

Step-by-step explanation:

let y = h(x) and rearrange making x the subject, that is

y = $\frac{3}{4}$ x + 12 ( multiply through by 4 to clear the fraction )

4y = 3x + 48 ( subtract 48 from both sides )

4y - 48 = 3x ( divide both sides by 3 )

$\frac{4y-48}{3}$ = x

Change y back into terms of x, thus

$h^{-1}$ (x) = $\frac{4x-48}{3}$

Olin [163]

Answer:

(a)

$40=1,2,4,5,8,10,20,40$

(b)

factor=5 can only hold it

(c)

Only one arrangement is possible

(d)

we can put 5 cans into all 8 shelves

(e)

$40=8\times 5$

Step-by-step explanation:

We are given

an empty kitchen cabinet has 8 shelves

and each shelf can hold no more than 30 cans you want to arrange 40 cans in the kitchen cabinet

so that the same number of cans is on each shelf that you use

(a)

we can find all possible factors of 40

$40=1,2,4,5,8,10,20,40$

(b)

Since, an empty kitchen cabinet has 8 shelves

so, one of factor of 40 must be 8

so,

$40=8\times 5$

So, factor=5 can only hold it

(c)

Only one arrangement is possible

because there is only one such possible factor

$40=8\times 5$

(d)

Since, we got

$40=8\times 5$

So, we can put 5 cans into all 8 shelves

(e)

Since, there are 8 shelves

and we can put 5 cans on each shelves

so, possible arrangement is

$40=8\times 5$
