GenaCL600 [577]

Answer:

1/3 is the simplified form for given expression.

Step-by-step explanation:

Given that:

=\sqrt[-3]{27}

By simplifying:

Radical sign will be removed as follows:

= 27^{-1/3}

For removing the "-" sign from power, base will be inverted:

= (1/27) ^ {1/3}

27 can also be written as 3 * 3 * 3 = 3^3

So,

= (1/3^3)^{1/3}

= 1^{1/3} / 3^{3* 1/3}

By simplifying we get:

= 1/3

i hope it will help you!

At present the sum of Monica's age and daughter's age is 44 years. . After 2 years Monica's age will be three times that if her
sergeinik [125]

Answer:

Monica's age = 34 years

Her daughter's age = 10 years

Step-by-step explanation:

Let Monica's age = x

Let her daughter'sage = y

x + y = 44   -------> equ 1

After 2 years:

Monica's age = x + 2

Her daughter's age = y + 2

x + 2 = 3 * (y+2)

x + 2 = 3y + 6

      x = 3y + 6 -2

      x = 3y + 4

Put x value in equ 1:

    3y + 4 + y = 44

            4y = 44 - 4

             4y = 40

               y = 40/4

               y = 10

x = 44 -10

x = 34

Q #5 please I need your help
mojhsa [17]

"Standard form" is the form ...

... ax +by = c

where a, b, c are mutually prime integers and the leading coefficient is positive. (If a ≠ 0, then it is "leading". If a = 0, then b is the leading coefficient.)

Of the choices offered, the only one that is equivalent to the given equation is ...

... -x + 6y = 5

_____

However, "standard form" requires the leading coefficient be positive, so an appropriate answer would be ...

... x -6y = -5

or

... 6y -x = 5

____

This is another one for my "broken question" file.

What is the discriminant of the quadratic equation 2x + 5x2 = 1?
Murrr4er [49]
5x^2+2x-1=0

Delta equation is:

\Delta =\frac{-b\pm\sqrt(b^2-4ac)}{2a}

but we are interested in b^2-4ac because it determines the discriminant

5^2-4*2*(-1)=25+8=33

33>0

which means that discriminant is positive :)
