Elena L [17]

Answer:

A. 4

Step-by-step explanation:

We can look at the number line and find B and A

we get

B=-7

A=3

now, we can find |B| and |A|

$|B|=|-7|=7$

$|A|=|3|=3$

now, we can find

|B|-|A|

now, we can plug values

$|B|-|A|=7-3$

$|B|-|A|=4$

So,

option-A

Answer:

$3\frac {6}{25} hrs \ or \ 3 hrs\ 14 mins \ 24 sec$

Step-by-step explanation:

The question calls requires one to get the product of the given time. Since first debate lasted for :

$1\frac {4}{5} \ hrs$

-and the second lasted

$1\frac {4}{5} hrs$ times more than the first then the second took then the first step will involve converting the mixed fractions into improper fraction which will be:

$\frac {9}{5}$

-Now multiplying

$\frac {9}{5}\times\frac{9}{5}\\\\=\frac{81}{25}=3\frac{6}{25}$ hrs

Find the least common multiple of: 12x^3y^2 and 15x^2y^5

allochka39001 [22]

Answer: $60x^3y^5$

Step-by-step explanation:

Least Common Multiple :The least positive number that is a multiple of two or more numbers.

To find : The least common multiple of: $12x^3y^2$ and $15x^2y^5.$

Since, $12x^3y^2=2\times2\times3\times x^3y^2$

$15x^2y^5=3\times5\times x^2y^5$

The least common multiple of: $12x^3y^2$ and $15x^2y^5.$ = $2\times2\times3\times5\times x^3y^5=60x^3y^5$ [take highest power of x and y ]

Hence, the least common multiple of: $12x^3y^2$ and $15x^2y^5.$ = $60x^3y^5$

If f(x)=3x+2, find f(f^-1(14))

krek1111 [17]

F(x) = 3x + 2x = 3f-1(x) + 2x - 2 = 3f-1(x)(x - 2)/3 = f-1(x)(14 - 2)/3 = f-1(14)12/3 = f-1(14)4 = f-1(14) f(f-1(14)) = f(4)f(4) = 3(4) + 2f(4) = 12 + 2f(4) = 14 A function and its inverse are inverse operations, like addition and subtraction. They undo each other. f(f-1(x) = x
