Answer:
x=13 and y=20.
Step-by-step explanation:
76 is what u use to try to find both variables. So...u set it up as 6x-2=76. You add 2 to both sides. The 2 cancels out. 6x=78. Divide by 6. x=13. On the other hand, set the other equation as (-4+4y)=76. open the parenthesis...-4+4y=76. add 4 to both sides. 4y=80. Divide by 4 on both sides....y=20. Reason why u couldnt see x is because the x looks faded with the numbers.

Step-by-step explanation:
Hey there!
It looked like people were helping you with the first 2, so l'll pick up from there.
3. The graph changes direction 3 times, so it shows 3 turning points.
4. x^4 is the minimum degree polynomial model, because there are 3 turning points.
5. Look at where the graph was highest. 180 appears to be the closest number to that peak, so 180 sec is correct.
6. Look at the rise again. Where is the accelaration placed on the left side of the chart? It looks to me like 3 is closest.
I'll be waiting in the comments if you need help. :)
