can you please add details to your question
Answer:
B
Step-by-step explanation:
Substitute the x value into the right side of the function and if the value obtained is equal to the y value of the point then it is a solution.
(0, - 4) → y = 5(0) - 4 = 0 - 4 = -4 ← True
(2, 6) → y = 5(2) - 4 = 10 - 4 = 6 ← True
(4, 20) → 5(4) - 4 = 20 - 4 = 16 ← False
(4, 16) → 5(4) - 4 = 20 - 4 = 16 ← True
(0, - 4), (2, 6), (4, 16) ← possible inputs and outputs

Answer:<em>
</em><em><u>
w =(-40-√4320)/-34=(20+6√ 30 )/17= 3.110
</u></em></h2><h2><em><u>
w =(-40+√4320)/-34=(20-6√ 30 )/17= -0.757</u></em></h2>
Step-by-step explanation: The prime factorization of 4320 is
2•2•2•2•2•3•3•3•5
To be able to remove something from under the radical, there have to be 2 instances of it (because we are taking a square i.e. second root).
√ 4320 = √ 2•2•2•2•2•3•3•3•5 =2•2•3•√ 30 =
± 12 • √ 30
√ 30 , rounded to 4 decimal digits, is 5.4772
So now we are looking at:
w = ( -40 ± 12 • 5.477 ) / -34
Two real solutions:
w =(-40+√4320)/-34=(20-6√ 30 )/17= -0.757
or:
w =(-40-√4320)/-34=(20+6√ 30 )/17= 3.110
