inn [45]

Answer:

-3/2

Step-by-step explanation:

In the picture attached, the complete question is shown.

The expression is:

\frac{ \frac{1}{2} }{ \frac{-2}{5}} + \frac{-1}{4}

You can rewrite the first term, expressing the division as a multiplication, that is, inverting the fraction in the denominator, as follows:

\frac{1}{2} \times \frac{-5}{2}+ \frac{-1}{4}

\frac{-5}{4} + \frac{-1}{4}

The addition of a negative fraction is simply the subtraction by that fraction:

\frac{-5}{4} - \frac{1}{4}

\frac{-5 - 1}{4}

\frac{-6}{4}

Which can be simplified dividing by two both numerator and denominator:

\frac{-3}{2}

Mrac [35]

Answer:

Well assuming you don’t need to simplify

44/100

0.44

44%

Step-by-step explanation:

Okay so fraction is easy, theres a 100 cubes in total, 44 are shaded in, 44/100 are shaded in which is the area in this scenario.

Decimal is basically moving the place area by a specific amount, in this case theres no whole number since the whole number is 1 or 100/100 and its 44/100 right now so it can’t be a whole number. Decimals go by tenths, hundreths, thousandths, etc. so in this case 44/100 is n the hundreth place since its over a hundred so its 0.44. Or you can move it twice to the right by the times of 0 that appears.

Percent basically means out of 100. So in this case its 44 out of a hundred or 44%

If f(x) and its inverse function, f^-1(x), are both plotted on the same coordinate plane, where is their point of intersection?
zloy xaker [14]

Answer:

Step-by-step explanation:

Their point of intersection, assuming there is one, will be somewhere on the line y = x.  This line, y = x, is the line of symmetry between a function and its inverse.  So if the two do in fact intersect, it will be at some point on that line
