Answer:

$x=-2,y=4$

Step-by-step explanation:

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

$y=x+6$

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

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

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

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

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

$x=-2$

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

Sliva [168]

Answer:

5 hours was Aaron at the sitter

Explanation:

Cost of baby sitting for the first hour: 10

Cost of baby sitting for additional hour= 12

Total cost of babysitting= 58

Since the cost of first hour is 10

Hence the remaining cost after first hour

= 54-10

=48

Which means 1 hour is consumed in the first hour

Now to calculate the remaining hours for every additional hour

= $\frac{48}{12}$

=4 hours

Hence the total hour Aaron was with the sitter

= 1 hour + 4 hours

= 5 hours
