<u>Part 1)</u> we have

------> equation A

------> equation B

Substitute the equation B in equation A

Find the value of x

the best approximation is the point

therefore

<u>the answer Part 1) is the option C</u>

<u>Part 2) </u>we have

equate equation A and equation B

Find the value of y

the solution is the point

<u>the answer Part 2) is </u>

the fourth is 6, and the next one is 3. :)

Answer:

5 big sleds and 1 small sled

Big sled=3 children

5 big sleds=3*5

3*5=15

5 big sleds=15 children

1 small shed=2 children

15+2=17

oof thats hard

Step-by-step explanation:

x=-3+√19, x=-3-√19

x^2+6x=10

x^2+6x-10=10-10

x^2+6x-10=0

a=1 b=6 c=-10 - use the quadratic formula

I hope this helps!
