The equation for a parabola can also be written in the "vertex form":
 y = a (x - h) ^ 2 + k
 In this equation, the vertex of the parabola is the point (h, k).
 We have then:
 y = a (x - (-5)) ^ 2 + -2
 Substituting the given point:
 2 = a (-4 - (-5)) ^ 2 + -2
 Clearing a:
 2 = a-2
 a = 4
 Answer:
 
a = 4
 
option B

padilas [110]
Answer:
*a general admission ticket is $160
*a grandstand ticket is $390

Explanation: make 2 equations from the provided information
**g is a grandstand ticket and a is a general admission ticket.

4g+2a=1880, 4g+4a=2200
Steps: 4g+2a=1880 changes to 4g=1880-2a because you move the 2a in order to solve for g.
You can substitute the 4g into 4g+4a=2200 to get 1880-2a+4a=2200 and simplify to get 1880+2a=2200. subtract 1880 from both sides and you get 2a=320. divide both sides by 2 to get a=160.
After that you can substitute the value for a into 4g+4a=2200 to get 4g+4(160)=2200. simplify to get 4g+640=2200. subtract 640 from both sides to get 4g=1,560. divide both sides by 4 to get g=390.

Hope this helped! :)

Tia states that the graph of g(x) = (x – 2)3 + 7 is a translation of 2 units to the left and 7 units up from f(x) = x3. Is Tia’s
Lina20 [59]

Answer:

No.

Step-by-step explanation:

Compare g(x) = (x – 2)^3 + 7 to f(x) = (x - h)^3 + k.  Here, h denotes horizontal translation and k denotes vertical translation.  Translation to the left by 2 units would be (x + 2)^3 + 7.  Translation to the right by 2 units would be (x - 2)^3 + 7.  So, no, Tia's description of horiz. translation is incorrect.

However, her adding 7 does denote a positive vertical translation.
