I am a 3-digit number. If you switch my first and last digits, I decrease by 297. Also, mymiddle digit is 6 less than my first digit, which is 2 less than 2 times my last digit. What
number am I?

Answers

Answer:

  • 865

Step-by-step explanation:

Let the 3-digit number is abc = 100a + 10b + c.

We have:

  • 100a + 10b + c - 100c - 10b - a = 297
  • b = a - 6
  • a = 2c - 2

Simplify the first equation:

  • 99a - 99c = 297
  • a - c = 3
  • a = c + 3

Solve for c by substitution:

  • 2c - 2 = c + 3
  • 2c - c = 3 + 2
  • c = 5

Find a:

  • a = 3 + 5 = 8

Find b:

  • b = 8 - 2 = 6

The number is:

Answer:

  x² +y² -6x -16y +48 = 0

Step-by-step explanation:

Given:

  • circle center: (3, 8)
  • circle radius: 5

Find:

  general form equation for the circle

Solution;

The standard form equation for the circle is ...

  (x -h)² +(y -k)² = r² . . . . . circle with radius r centered at (h, k)

  (x -3)² +(y -8)² = 5²

Subtracting 25 and expanding this will give the general form.

  x² -6x +9 +y² -16y +64 -25 = 0

  x² +y² -6x -16y +48 = 0

Additional comment

"General form" of an equation is usually the form f(x,y) = 0, where f(x, y) is written in "standard form," with terms in lexicographical order and decreasing degree.

Given the equation 5(-2x -10) = 25(x + 1), solve for the value of x that will make the equation true.

Answers

Answer:

Step-by-step explanation:

5(-2x -10) = 25(x + 1)

-10x - 50 = 25x + 25

by transposing

-10x - 25x = 25 + 50

-35x = 75

x = -75/35

x = 15/7

or 2.142857..... in decimal

\huge\text{Hey there!}

\huge\textbf{Equation:}

\mathsf{(3)/(4)a > -16}

\huge\textbf{Simplifying it:}

\mathsf{(3)/(4)a > -16}

\mathsf{(3)/(4)a > - (16)/(1)}

\huge\textbf{Divide \boxed{(4)/(3)} to both sides:}

\mathsf{(4)/(3)*(3)/(4)a > -16*(4)/(3)}

\huge\textbf{Simplify it:}

\mathsf{a > (4)/(3)* -16}

\mathsf{a > - (16)/(1) *(4)/(3)}

\mathsf{a > (-16*4)/(1*3)}

\mathsf{a > (-64)/(3)}

\mathsf{a > -(64)/(3)}

\mathsf{a > -21 (1)/(3)}

\huge\textbf{Therefore, your answer should be:}
