Step-by-step explanation:

Set-builder notation is a notation for describing a set by indicating the properties that its members must satisfy.

C={2,4,6,8}

C={2×1,2×2,2×3,2×4}

thus set builder form is:

{x:x=2n,n∈N} and this set is also call even number set in description mathod

HELP! The diagonal length of a kite is multiplied by 8. Which of the following describes the effect of this change on the area?

jeka57 [31]

Answer:

The area is multiplied by 8.

Step-by-step explanation:

I am pretty sure I multiplied the two diagonals that I randomly selected then multiplied the longest diagonal by eight multiples them together again then divided the bigger area by the smaller area, however, but you might want to double-check the work but the answer is right

The quotient of-54 and 9, subtracted from 8 times a number, is-18

AysviL [449]

The number is: " -3 " .
_____________________________________
Explanation:
_____________________________________
Let "x" be the "unknown number" for which we are to solve.

8x − (-54/9) = -18 ; Solve for "x" ;

→ 8x − (-6) = - 18 ;

→ 8x + 6 = - 18 ;

Subtract "6" from each side of the equation:

→ 8x + 6 − 6 = - 18 − 6 ;

to get: 8x = -24 ;

Divide EACH SIDE of the equation by "8" ; to isolate "x" on one side of the equation ; & to solve for "x" ;

8x / 8 = -24 / 8 ;

to get: x = -3 .

10. 10x + 5y = 15

Westkost [7]

Answer:

x = 1.5

y = 0

Step-by-step explanation:

10x + 5(2x - 3) = 15

10x + 10x - 15 = 15

20x - 15 = 15

20x = 30

x = 1.5

y = 2(1.5) - 3

y = 3 - 3

y = 0

Check:

10(1.5) + 5(0) = 15

15 + 5(0) = 15

15 + 0 = 15

15 = 15
