Answer:
D. (2, 6)
Step-by-step explanation:
Look at the picture.
Check:
(2, 6) → x = 2, y = 6
Put the coordinates of the point to the inequalities:
y < x² + 6
6 < 2² + 6
6 < 4 + 6
6 < 10 TRUE
y > x² - 4
6 > 2² - 4
6 > 4 - 4
6 > 0 TRUE
1/x-3/4+1/2+x Solve for x

Answer:
42. Graph a
43. Not possible.
44. Graph e
45. Graph c
46. Graph b.
Step-by-step explanation:
42. 7x + 13 ≥ 55
⇒ x ≥ 6
So, it matches graph a.
43. 12x - 8 > 4(3x + 2)
⇒ 12x - 8 > 12x + 8
Hence, d. not possible.
44.
⇒
⇒ x > - 8
Hence, graph e matches.
45. - 4(- 2x + 3) ≤ 5 + 8x
⇒ 8x - 12 ≤ 5 + 8x
⇒ - 12 ≤ 5
This is true for all values of x, hence that matches graph c.
46. - 4(x + 3) > 8(x + 3)
⇒ - 4x - 12 > 8x + 24
⇒ 12x < - 36
⇒ x < - 3
Hence, graph b matches the situation. (Answer)
