Answer:
<em>She can fill 19 pots.</em>
Step-by-step explanation:
Yao Xin puts liters of potting soil in each pot.
Suppose, the number of pots Yao Xin can fill is
So, <u>the total amount of potting soil</u> in number of pots will be:
liters.
Given that, she has liters of potting soil. So, the equation will be........
So, she can fill pots.
Answer:
x ≥ -1/2
Step-by-step explanation:
We know that we cannot graph imaginary numbers. Therefore, our <em>x </em>value has to be greater than or equal to 0:
To find our domain, we need to set the square root equal to zero:
√(4x + 2) = 0
4x + 2 = 0
4x = -2
x = -1/2
We now know that no value below -1/2 can be used or we will get an imaginary number. Therefore, our answer is x ≥ -1/2
Alternatively, we can graph the function and analyze domain:
