Answer:

  1.4

Step-by-step explanation:

The average rate of change is the "rise" divided by the "run".

  rise/run = (f(4) -f(-1))/(4 -(-1)) = (0 -(-7))/(4+1)

  rise/run = 7/5 = 1.4

The average rate of change on the interval [-1. 4] is 1.4.

The equation that does not justify the similarities of both triangles is:

\frac{RQ}{RT}= \frac{PQ}{ST}

<h3>Similar triangles</h3>

Similar triangles may or may not have congruent sides.

The triangles are given as:

  • Triangle PQR
  • Triangle STR

The above means that, the following sides are similar

  • Line segments PQ and ST
  • Line segments QR and TR
  • Line segments PR and SR

So, the equation that does not justify the similarities of both triangles is:

\frac{RQ}{RT}= \frac{PQ}{ST}
