4:45 -3:30 -2*(0:15) = 0:45

Gina and Lucy can spend 45 minutes at the library.

_____
They will get to the library at 3:45. They must start home by 4:30. From 3:45 to 4:00 is 15 minutes, and it is 30 more minutes to 4:30. The time they can spend at the library totals 45 minutes.

The graph shows g(x), which is a translation of f(x)=|x|. Write the function rule for g(x).
Kay [80]

Answer:

  g(x) = |x| -9

Step-by-step explanation:

In the form ...

  g(x) = a|x -h| +k

the parameters are ...

  • a: the vertical scale factor (1)
  • h: the right shift of the vertex (0)
  • k: the upward shift of the vertex (-9)

The vertex of |x| is (0, 0). The vertex of g(x) is (0, -9), so there has been a vertical shift of -9 and no horizontal shift. The slopes of the lines on the graph of g(x) have a magnitude of 1, so the vertical scale is not changed from the original function (a=1).

Then the translated function is ...

  g(x) = |x| -9

denis23 [38]

Answer:

y = 20/3

Step-by-step explanation:

4y + 2y + 10 = 50

Combine like terms on the left side.

6y + 10 = 50

Subtract 10 from both sides.

6y = 40

Divide both sides by 6.

y = 40/6

Reduce the fraction by dividing the numerator and denominator by 2.

y = 20/3
