max2010maxim [7]

Answer:

f(7) = 11

Step-by-step explanation:

<em>t</em> = 7, so we can just plug in the value 7 for (t) in the given equation.

f(t) = 2t - 3

  f(7) = (2 × 7) - 3

  f(7) = 14 - 3

  f(7) = 11

Help please..............
eimsori [14]
I believe the correct answer here would be B. The values x=2 and y=5 make the equation true. The answer is not A, because the graph could also go through 3 and 6. It is not C because that is not the correct order. The answer is not D because D is absurd and does not make sense.
