Devaughn is 15 years older than sydney. the sum of their ages is 87 . what is sydney's age?

Subtract the difference in age from the total:

87 - 15 = 72

Divide by 2:

72 / 2 = 36

Sydney is 36 years old

Devaughn is 15 years older: 36 +15 = 51 years old

51 + 36 = 87

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
