Is the point (4,2) the solution to the system? Why or why not? Explain your reasoning.

1 answer:

4 0

Solve the top equation to get on variable on one side
2x-y=6
-y=-2x+6
y=2x-6
then plug in the coordinate for x and y for both equations. if both equations are true then it’s a solution
2=2(2)+6
2=10

4+2=6

so it’s not a solution

Aleks [24]

Answer: They spend 5.368 × 10⁹ all together on ice cream and baby food between 2008 and 2009.

Step-by-step explanation:

Since we have given that

Amount spent on baby food between 2008 and 2009 = $8.48\times 10^8$

Amount spent on ice cream between 2008 and 2009 = $4.52\times 10^9$

We need to find the total amount spend all together on ice cream and baby food.

Total amount would be

$8.48\times 10^8+4.52\times 10^9\\\\=5.368\times 10^9$

Hence, they spend 5.368 × 10⁹ all together on ice cream and baby food between 2008 and 2009.
