Answer:

The answer is x+20⩾50

Step-by-step explanation:

in inequality, the word at least means that is equal or more than. so that means that Allie might equal or more than 50 hours in the model but if you're to solve it, Allie will need 30 or more hours. and since she already has 20, add the 20.

The graph of f(x) = x3 + x2 - 9x - 9 is shown.
AysviL [449]

Answer:

-1, 3, -3

Step-by-step explanation:

I don't see the graph, but you can solve by factoring:

x^3+x^2-9x-9=0\\x^2(x+1)-9(x+1)=0\\(x+1)(x^2-9)=0\\(x+1)(x+3)(x-3)=0

By the factor theorem, the solutions of f(x) are -1, 3, and -3.

What is the correct description for the graph of the inequality, y &lt; 42 – 3?
Varvara68 [4.7K]
Answer: The graph is a solid line. The test point (0,0) does not satisfy the inequality.


Explanation:
The line is solid because it is less than or EQUAL TO. The test point does not satisfy because if you replace y and x with 0, it will not be true. 0 is not less than or equal to -3, therefore (0,0) does not satisfy the inequality.
