option (b) is correct.
to prove the above stated formula we have to choose one of the identity from the given options .
since right side of above formula is which is same as , we will use the identity
we know and
substitute above, we get,
thus, option (b) is correct.
y= mx+b where m represent the slope aka x intercept. b represent the initial value aka y intercept. hope it !
put x = 3 and y = 5 to the expressions 3x² - 2y and 2x² - 3y.
p parentheses first
e exponents (ie powers and square roots, etc.)
md multiplication and division (left-to-right)
as addition and subtraction (left-to-right)
3x² - 2y
3 · 3² - 2 · 5 = 3 · 9 - 10 = 27 - 10 = 17
2x² - 3y
2 · 3² - 3 · 5 = 2 · 9 - 15 = 18 - 15 = 3
make the difference:
17 - 3 = 14
