If you flipped the graph y=x^2+2x-2 vertically, you would get the graph y=-(x^2+2x-2) this is True.
Shobo's age = x years
His mother's age = 6 times of Shobo's age
= 6x years
Five years from now
________________
Shobo's age = ( x + 5 ) years
According to the problem given,
x + 5 = one by third of his mother's
present age
x + 5 = 6x / 3
x + 5 = 2x
5 = 2x - x
5 = x
Therefore ,
Shobo's present age = x = 5 years
His mother's age = 6x
= 6 × 5
= 30 years

Cancel y values
multiply 2nd equation by 4 and add to first
-9x+4y=8
<u>-12x-4y=16 +</u>
-21x+0y=24
-21x=24
divide both sides by -21
x=24/-21
x=-8/7
C is answer
Yes, because there is a 50 50 chance that it can land head or tails.
