Step-by-step explanation:
Answer:
A. (5,5)
Step-by-step explanation:
- Plug in (5,5) for the x and y values according to the ordered pair. In this case the equation should turn out like this :5 ≤ 5²- 4(5) + 2
- Simplify the equation : 5 ≤ 25 - 20 + 2
- 5 ≤ 7
- A is the answer because it satisfies the inequality as 5 is less than or equal to seven. Though, in this case it is just less than, but not equal to.
Answer:
8,5
Step-by-step explanation:
x-y=3
x+y=13
2x=16
x=8, y=5
(A) 2/3A= -24
A= -24 • 2/3
A= 48/3
A= 16
(B) 20= -B/0.2
20 • 0.2= -B
4= -B
-4= B
(C) Distance between Point A & Point B is 20
