. If mZJ= (7x + 13)", mZK = (83 - 2x), and
OLga [1]

Answer:

  • m∠J = 76°
  • m∠K = 65°

Step-by-step explanation:

The sum of angle measures is ...

  (7x +13)° +(83 -2x)° = 141°

  5x +96 = 141 . . . . . collect terms, divide by °

  5x = 45 . . . . . . . . . subtract 96

  x = 9 . . . . . . . . . . . divide by 5

  7x +13 = 7·9 +13 = 76 . . . . . find m∠J

  m∠J = 76°

  m∠K = 141° -76°

  m∠K = 65°

In Exercises 17-20, find the value of x so that the function has the given value. 17. f(x) = 8x - 7; f(x) = 17
Nastasia [14]

Answer:

17.) x = 3

18.) x = -5

I couldn't do 19.) and 20.) for you because there are weird symbols that I believe you mistakenly input. But I'm sure you now get the gist of how to solve such problems. Peace <3

Step-by-step explanation:

All you really have to do for all of the problems is substitute your value of "x" for the function.

17.) f(x) = 8x - 7; f(x) =17

    17 = 8x -7  ---- substitute 17 for f(x), add 7 on both sides

    24 = 8x ------ divide 8 on both sides

    x = 3

18.)    g(x) = -4x + 7; g(x) = 27

           27  = -4x + 7  substitute 27 for g(x), subtract 7 on both sides

           20 = -4x

            x = -5
