Answer:
28
Step-by-step explanation:
Yes. Point symmetry is effectively where an object is "the same upside down", or where every point has an identical counterpart the same distance from the point in the opposite direction. H can be flipped and remain symmetrical
Answer:
2/3x - y= 4
Step-by-step explanation:
first you subtract 2/3x from both sides
-2/3x + y= -4
then you divide both sides by -1
2/3x - y= 4
If you add them straight down:
2d-e = 7
d + e = 5
Then the e's cancel out.
You are left with 3d = 12
Then solve for d by dividing each side by 3.
Now you have d =4.
To solve for e go back into one of your original equations and substitute 4 for the d.
You can use either equation, so I'll choose the second one.
4 + e = 5
Now solve for e by subtracting each side by 4.
Now you have e = 1.
So your solutions are d = 4 and e = 1
