Y < 4x + 3....this will be a dashed line with shading under the line
slope = 4....y int = (0,3)....x int = (-3/4,0)

y > -3x - 3...this will be a dashed line with shading above the line
slope = -3....y int = (0,-3)...x int = (-1,0)

** u can go to desmos calculator to see the graph


one solution is (0,0)
y < 4x + 3...subbing in (0,0)
0 < 4(0) + 3
0 < 3 (correct)

y > -3x - 3...subbing in (0,0)
0 > -3(0) - 3
0 > -3 (correct)

Stuck, anyone can help?
expeople1 [14]

Answer:

Step-by-step explanation:

\sqrt{x-3} = x - 5 ( x ≥ 3 )

( \sqrt{x-3} )² = ( x - 5 )²

x - 3 = x² - 10x + 25

x² - 11x + 28 = 0

(x - 4)(x - 7) = 0

x_{1} = 7

x_{2} = 4

Check the answer:

1). x = 7

\sqrt{7-3} = 7 - 2

√4 = 2

2 = 2

2). x = 4

\sqrt{4-3} = 4 - 5

1 = - 1 (False statement) ⇒ x = 4 is an extraneous solution.
