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:
A) (5, 5)
Step-by-step explanation:
Put the coordinates of the points to the inequality, and check:
y ≤ x² - 4x + 2
for (5, 5) → x = 5, y = 5
5 ≤ 5² - 4(5) + 2
5 ≤ 25 - 20 + 2
5 ≤ 7 CORRECT :)
===============================
for (2, 2) → x = 2, y = 2
2 ≤ 2² - 4(2) + 2
2 ≤ 4 - 8 + 2
2≤ -2 FALSE
===============================
for (4, 4) → x = 4, y = 4
4 ≤ 4² - 4(4) + 2
4 ≤ 16 - 16 + 2
4 ≤ 2 FALSE
================================
for (1, 1) → x = 1, y = 1
1 ≤ 1² - 4(1) + 2
1 ≤ 1 - 4 + 2
1 ≤ -1 FALSE
