Part A: Explain why x = 5 makes 4x - 1 5 19 true but not 4x - 1 < 19.
Westkost [7]

9514 1404 393

Answer:

  • 19 ≤ 19 . . . true
  • 19 < 19 . . . false
  • x = 9

Step-by-step explanation:

A) A number cannot be less than itself, but can be equal to itself.

In each case, the left side of the inequality evaluates to 19:

  4(5) -1 = 20 -1 = 19

It is true that 19 is less than or equal to 19. This is true because 19 = 19.

It is not true that 19 is less than 19. A number cannot be less than itself.

__

B) 5x +2 = 47

  5x = 45 . . . . . . subtract 2 from both sides

  x = 9 . . . . . . . . . divide both sides by 5

The element 9 from the set is the solution to the equation.

What is the sum? 3k/k^2+k-7/4K
Aleksandr-060686 [28]

Answer:

  \dfrac{k^2+5k}{4k^2}

Step-by-step explanation:

A suitable common denominator is 4k^2. (This eliminates the first and last choices.)

\dfrac{3k}{k^2}+\dfrac{k-7}{4k}=\dfrac{4(3k)}{4(k^2)}+\dfrac{k(k-7)}{k(4k)}\\\\=\dfrac{12k+k^2-7k}{4k^2}=\boxed{\dfrac{k^2+5k}{4k^2}}

In this equation, y-4/2=10, would i need to get the same denominator<br> y-4/2=10/2 = y-2=5?
Natasha_Volkova [10]
No actually you can just multiply both sides of the equation by 2 and get y-4=20. then add 4 to both sides to get y=24.
