)is on the line 4x + 5y = -7. find the other half of the coordinate.

 The other half of the co-ordinate is 2.

Step-by-step explanation:  Let, 'b' be the other half of the co-ordinate (?, -3) that lies on the given straight line as follows:

So, we can say that the point (b, -3) lies on the line (i). That is, the point (b, -3) will satisfy equation (i).

Substituting (x, y) = (b, -3) in equation (i), we get

Therefore, the value of 'b' is 2.

Thus, the other half of the co-ordinate is 2. And the complete co-ordiantes are (2, -3).

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
