If y = -16 when x = 4, find x when y = 32. x =

Andrei [34K]

Answer: I think the answer is x=16

Step-by-step explanation:

y=-16 x=4

+16 +4

so in order to get a positive number i added 16 to y and 4 to x which equals

y=0 x=8

y=0 x= 8

+16 +4

I added another 16 to y and another 4 to x = y=16, x=12

y= 16 x=12

+16 +4

I added another 16 to y and another 4 to x = y= 32 x= 16

so the answer for x is 16

hopefully i got it right

<h2>Intersection and Union of Sets</h2><h3>Answer:</h3>

$A \cup B = \{ a, b, c, d, e \}$

$B \cap C = \{ d, e \}$

$A \cup C = \{ a, b, c, d, e, f \}$

<h3>Step-by-step explanation:</h3>

Given:

$A = \{ a, b, c, d \}$

$B = \{ b, d, e \}$

$C = \{ d, e, f \}$

The Union ( $\cup$ ) of sets $A$ and $B$ is just a set containing all the elements of sets $A$ and $B$ . However, elements that are present in both sets should not repeat in the Union of Sets as the elements of a set should distinct be from each other.
