Answer:
(-3, 4)
Step-by-step explanation:
First, add 3 to point B's x coordinate:
-6 + 3 = -3
Then, add 1 to the y coordinate:
3 + 1
= 4
So, the coordinates of pre image point A are (-3, 4)

Answer:
25
Step-by-step explanation:
X² = 7² + 24²
X² = 49 + 576
X² = 625
X = 25
Answer:
{10,8}
Step-by-step explanation:
-3x + 4y = -62
4x + 5y = 0
let's eliminate the x
-3x + 4y = -62 | x -4 |
4x + 5y = 0 | x 3 |
12x - 16y = 248
12x + 15y = 0
-------------------- -
-31y = 248
y = 248/(-31) = 8
since you must do this proble with elimination, we cant use subtitution. so we repeat the way once more to find x (eliminate y)
-3x + 4y = -62 | x 5 |
4x + 5y = 0 | x 4 |
-15x + 20y = -310
16x + 20y = 0
-------------------- -
-31x = -310
x = -310/-31 = 10
