(-2,-5)
because
y= y
x^2+10x+ 11 = x^2+x -7
10x-x = -7-11
9x=-18
x=-2
so y = (-2)^2+(-2)-7 = 4-2-7 =-5
This is an opinion question.
Lets say you are x
20<2x<40
therefore x has to be greater than 10, but less than 20
6x=_8
the only numbers between 10 and 20 that works with this equation are 13 and 18
(6x13=78 and 6x18=108)
3(-5)-9 = -24 plug in -5 for x
