The answer is A.
We can first eliminate D since it uses these (<, >) signs and the lines are shaded, indicating the points on those lines are solutions.
We can also eliminate C because the y intercept in C’s lines is 2, while in the graph, they are both 3.
Finally, we can look at both inequalities on the graph and see that the shaded areas are both underneath the line. This means that y is less than the equation for the line, eliminating B
So, the answer is A
Hope this made sense!!
Yeah I think so you have to solve and break it down
Your problem statement needs a bit of correction:
"<span>Y= -16t^2 +400, where t represents the number OF SECONDS after the camera is dropped. How long will it BE before Kay sees the splash from the camera hitting the water?"
Set y = -16t^2 + 400 = 0. We assume that 400 and 0 represent feet (English system).
Then 16t^2 = 400, and so 25 = t^2. Only the positive square root makes sense here, and that root is 5 (seconds).</span>
7. is C 3/50
8. is H 2/3
9. is C 2/3
10. is B slope 4 y intercept -2
11. is -1/4 slope
12. is 1/5 slope
13. is -2/3 slope
14. is 6 is the slope
15. is y=5/3x+5
16. is y=1/2x-3
17. is y=-3/5x+4
18. is y=3/2x-3 :)
