Answer:
The last choice is the one you want
Step-by-step explanation:
First of all, a parabola has a minimum value if it is a positive parabola, one that opens upward. The first and the third parabolas are negative so they open upside down. That leaves us with choices 2 and 4. We find the side to side and up or down movement by finishing the completion of the square that has already been started for us. Do this by factoring what's inside the parenthesis into a perfect square binomial.
The second one factored becomes:
which reflects a shift to the right 3 and up 1. Not what we are asked to find.
The fourth one factored becomes:
which reflects a shift to the right 3 and down 5. That's what we want!
The best and most correct answer among the choices provided by your question is the first choice or letter A.

Answer:
answer iy in the picture...
Part A is accomplished by first factoring out the b^2 to get
. Factor that completely using the quadratic formula to get
. Part B is done entirely with the quadratic formula (only cuz that's the easiest way to factor a second degree polynomial!) to get (x-9)(x-9) or (x-9) multiplicity 2. Part C is done by taking roots. Keep in mind that since this is a second degree polynomial you will have 2 solutions.
, therefore,
and
which is +11 and -11. And you're done! Factoring is very important...make sure you learn it and learn it well!!!
Answer:
t = $23
s= $47
Step-by-step explanation:
First order =
13t + 4s = 487
Second order
6t + 2s = 232
13t + 4s = 487 (1)
6t + 2s = 232 (2)
Multiply (2) by 2
12t + 4s = 464 (2b)
13t + 4s = 487
12t + 4s = 464
Subtract
12t - 10t = 487 - 464
t = $23
Substitute t = 23
13t + 4s = 487
13(23) + 4s = 487
299 + 4s = 487
4s = 487 -299
4s = 188
s = 188 / 4
= 47
s= $47
