\huge\text{Hey there!}

\huge\textbf{Solving for your equation:}

\mathbf{|4x^2| - 3x - (9 - |-3x|)}

\mathbf{= |(4)(9)|-(2)(-3)-(9-|(-3)(-3)|)}

\mathsf{= |36| - (2)(-3)- (9 - |(-3)(-3)|)}

\mathbf{=36 - (2)(-3) - (9 - |(-3)(-3)|)}

\mathbf{= 36 -(-6) - (9 - |(-3)(-3)|)}

\mathbf{= 42 - (9 - |(-3)(-3)|)}

\mathbf{= 42 - (9 - |9|)}

\mathbf{= 42 - (9 - 9)}

\mathbf{= 42 - (0)}

\mathbf{= 42 - 0}

\mathbf{= 42}

\huge\textbf{Notice that your equation kept getting}\\\huge\textbf{getting smaller and smaller?}\\\\\\\huge\textbf{That's because we kept solving as we got}\\\huge\textbf{closer to your result and we got there}\\\huge\textbf{sooner than we thought :)}

\huge\textsf{ANYWAY!}

\huge\textsf{Therefore, the answer is: \boxed{\mathsf{Option\ D. 42}}}\huge\checkmark

\huge\text{Good luck on your assignment \& enjoy your day!}

What is the algorithm for the inverse of f (x)?<br>​
Juli2301 [7.4K]

Answer:

What is an inverse?

Recall that a number multiplied by its inverse equals 1. From basic arithmetic we know that:

The inverse of a number A is 1/A since A * 1/A = 1 (e.g. the inverse of 5 is 1/5)

All real numbers other than 0 have an inverse

Multiplying a number by the inverse of A is equivalent to dividing by A (e.g. 10/5 is the same as 10* 1/5)

What is a modular inverse?

In modular arithmetic we do not have a division operation. However, we do have modular inverses.

The modular inverse of A (mod C) is A^-1

(A * A^-1) ≡ 1 (mod C) or equivalently (A * A^-1) mod C = 1

Only the numbers coprime to C (numbers that share no prime factors with C) have a modular inverse (mod C)

Can someone help me and give an explanation
Kitty [74]

Two triangles: left triangle with y degrees and 40 degrees and right triangle with x degrees.

  • 40 degrees from the left triangle, when adding with the unknown angle of the right triangle, is equal to 180 degrees.
  • Adding left triangle's (third) undetermined angle and x degrees angle (the other same angle), is equal to 90 degrees.
  • The right triangle is an isosceles triangle, meaning two equal angles, and one of them is x degrees. Thus, the other same angle is also x degrees.

----------------------------------------------------------------------------------------------------------

1) Subtract 180 - 40 = 140 degrees. 140 degrees is the unknown angle of right triangle.

2) 140 + x + x = 180 (equation)

  • 140 + 2x = 180
  • 2x = 180 - 140
  • 2x = 40
  • x degrees = 20 degrees

ANSWER: x = 20 DEGREES

----------------------------------------------------------------------------------------------------------

1) With knowledge of x degrees being 20 degrees, the other same angle is 20 degrees, too.

2) Subtract 90 - 20 = 70 degrees. 70 degrees is the (third) undetermined angle

of left triangle.

2) 70 + 40 + y = 180

  • 110 + y = 180
  • y = 180 - 110
  • y = 70 degrees

ANSWER: y = 70 DEGREES
