Answer:
The local minimums is the point of a function with lowest output (Locally). In this case, the values at which the function has a local minimum is: (-2, -3) and (4, -5).
All local minimum values of f are: (-2, -3) and (4, -5), given that the point (1, -1) is a local maximum.
Ok so
t=number of text messsages
p=number of picture messages
total number is 33
t+p=33
if text is 0.18 per pic and picture is 0.45 per text
total cost is 8.3
0.18t+0.45p=8.3
times 100 both sides for ease
18t+45p=830
we now have 2 equations
t+p=33
18t+45p=830
multiply first equation by -18 and add to second equation
18t+45p=830
<span>-18t-18p=-594 +</span>
0t+27p=236
27p=236
divide both sides by 27
p=8.740740740740744
this is impossible becasue you can't send 0.740740740740744 of a message so you did a mistype somewhere
