erik [133]

Easy! If Smith had four daughters who each had 4 kids, then he had a total of 20 kids. I got this by multiplying the daughters by their kids, 4x4, and adding the four daughters, so it equals 20 kids in total!

Solution to the system<br> y=-x2-3x+2<br> y=x+6

worty [1.4K]

Answer:

$x=-2,y=4$

Step-by-step explanation:

$y=-x^2-3x+2$

$y=x+6$

$x+6=-x^2-3x+2$

$x^2+x+6=-3x+2$

$x^2+4x+6=2$

$x^2+4x+4=0$

$(x+2)(x+2)=0$

$x=-2$

$y=(-2)+6=4$
