Hello,
2 possibilties:
1) a translation to the right of 5 (both parabolas are turning upward)
2) a central symetry( center is (-1.5,-6)
parabolas does not have the same direction upward and downward.
Hi!
When a number has lines on the outside of it like that, it means that it's the distance from 0. It's known as the absolute value.
|−8.6|'s distance from 0 is 8.6.
The answer is d 8.6
Hope this helps! :)

2.5y + 3x = 27
5x - 2.5y = 5
Align the variables to make solving this easier.
2.5y + 3x = 27
-2.5y + 5x = 5
You can see that the 2.5y and -2.5y cancel each other out. Then add the 3x and 5x, and 27 + 5.
3x = 27
5x = 5
8x = 32
Divide both sides by 8.
x = 4
Now input that x into one of the equations to get y.
2.5y + 3(4) = 27
2.5y + 12 = 27
2.5y = 15
y = 6
The answer to this system of equations is x = 4, y = 6. (4, 6)

7/8 + 8/9 = 1 55/72
1 55/72 x 4 =
1 = 72
72 + 55 = 127
127/72 x 4/1 = 504/288
504/72 = 7/1
7
Even tho 7 isn´t an option I would pick A. because it is the closest
Answer:
sec A = 5/4
Step-by-step explanation:
Sec of an angle is hypotenuse/adjacent side
In your problem, sec A = 25/20 = 5/4
It helps if you can draw a figure of the problem. Make sure you memorize the definition of each trig function
