Answer:
Approximately 163 seconds (A)
Step-by-step explanation:
Line up 192 months on the x-axis with the line of best fit then run it across to the y-axis and it should be around 163 seconds.
6 into 30 is 5 & 6 into 48 is 48. She needs a total of 6 plastic containers
Start by looking at the vertex form of a quadratic function, f(x) = a(x - h)^2 + k. The variables h and k are the values of the vertex. Plug those in to get f(x) = a(x - 4)^2 + 5. To find the variable a, plug in the point given for the x and y values. So, you get (21) = a((8) - 4)^2 + 5. Solve for a algebraically, and you get a = 1. Finally, plug everything in and simplify the equation. You should get that the quadratic function is f(x) = x^2 - 8x + 21. Hope this helps!
Answer for 7: C
Answer for 9: A
Step-by-step explanation for 7:
Because the variable is an exponent, we know there are no real numbers which cannot be placed in the exponent. Therefore, the domain is all real numbers.
Step-by-step explanation for 9:
Test a few values for x. Notice as the x value gets higher, the y value gets exponentially higher. Notice as the x value gets lower, the y value approaches 0, but no value of x will have y equal to or less than 0. Therefor, the asymptote, or line that cannot be crossed is 0 - making A the correct solution.

General notes:
- When it says below, under, negative, owes, then that indicates a negative quantity.
- If it say over, altitude, height, then that indicates a positive integer.
