Justine correctly used completing the square to rewrite the quadratic expression 2x2 – 12x + 25 as 2(x - 3)2 + 7.
After seeing the new form of the expression, Justine
said that the expression had a minimum value of 7
when xis -3. Is Justine right?

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
