Answer:

  • -2.5

Step-by-step explanation:

<u>Evaluate the expression:</u>

  • b²/(a + 5)

When a= −15 and b=−5

<u>Substitute values:</u>

  • b²/(a + 5) =
  • (-5)² / (-15 + 5) =
  • 25/(-10) =
  • -2.5

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

<u>In case the expression is b²/a + 5, the value is:</u>

  • b²/a + 5 =
  • (-5)²/(-15) + 5 =
  • 25/(-15) + 5 =
  • - 5/3 + 5 =
  • 10/3

ELEN [110]

Answer:

Step-by-step explanation:

You can easily find the slope by using two points. Let’s use (13, 11) and (14, 6)

We look at the slope equation as: y2 - y1 divided by x2 and x1.

13 = x1 11= y1 and 14= x2 6=y2

Plug in: 6-11/14-13 and solve

Answer: -5

Hope I made sense :)
