Just replace x with whatever , and see if it works. If it works then it is a solution; otherwise it's not.
1^2 is not 2
(1/2)^2 isn't 2 either...
and so on
Greater than! With negative numbers, the number closer to 0 is always the greater value. The number farther away from 0 is the lesser value. When we compare fractions with the same denominator, we have to compare to numerator. -2 is greater than -4, therefore -2/9 is greater than -4/9.
Step-by-step explanation:
to work out gradient
change in y ÷ change in x
first lines gradient
(7 - - 8) ÷ (7 - 7) = 0
second lines gradient
(7 - 7) ÷ (9 - - 6) = 0
Energy = (mass)(speed of light)squared
