the given sets are,
D= {4,7,9} , let E {4,6,7,8}, and let F={3,5,6,7,9}
now,
D U E = { 4 , 6, 7 , 8, 9}
and'
E intersection F = E n F = {6 , 7)
thus, the answer is
D U E = { 4 , 6, 7 , 8, 9} and
E n F = {6 , 7)
Answer: 20 and 22
The product of 20 and 22 is 440 and 22 is 2 more than 20.
Since both equations are equal to y you can just make them equal to each other, like this 3x + 7 = x - 9. From there isolate the varible x on one side so that the solution will be on the other side of the equation. I'll do the steps too for you.
3x + 7 = x - 9
2x + 7 = -9
2x = -16
x = -8
Hope this helps :)
Answer:
(1,4), (2,2) (3,0)
Step-by-step explanation:
adjust the equation so that the y is isolated so subtract 4 x
2y=4x +12
Every number is divisible by 2 so you can further isolate the y
y=-2x+6
Plug your x coordinates into the equation so get the y coordinates
