The answer is 1.25. yes it is rational because you can write it as a fraction
Percent=out of 100
45/100=45/
It is given in the question that
Point N(7, 4) is translated 5 units up.
And we have to find the coordinates of its image after this transformation.
Since the point translated up by 5 units, so the x coordinate remains same and we have to add 5 to y coordinate.
So the new coordinate after the transformation is

And that's the required coordinate after the given transformation .
X^2+12x-28
(x-2)(x+14)
Solve for x
x-2=0
x=2
x+14=0
x=-14
