Range: {y | y ∈ R, -3 <= y <= 4}
Answer:
about $1.67
Step-by-step explanation:
Divide.
= about $1.67
You can check your answer by multiplying:
1.67 x 12 = about 20
Just by looking at the answer choices, you can eliminate the last one because it is greater than the original price. And the first one is way too less, so your answer is B

Answer: C. x+9</h3>
===============================================
Explanation:
Think of two numbers that multiply to -36 and also add to 5. Put another way: think of two factors of -36 that add to 5.
Those two numbers are 9 and -4 since
9 times -4 = -36
9 plus -4 = 5
So we have x^2 + 5x - 36 factor into (x+9)(x-4)
x+9 is one factor
x-4 is the other factor

Alternatively, you can use a graphing tool to locate the x intercepts, and that will in turn lead to the factorization. Or you could use the quadratic formula to get the job done. Completing the square is yet another tool to use. So there are multiple approaches.
