Answer:
Option C. the volume of water in the tank is decreasing by 0.4L per hour
Step-by-step explanation:
step 1
Find the slope
we know that
The formula to calculate the slope between two points is equal to
we have
Substitute the values
The slope is negative
so
is decreasing
That means------> the volume of water in the tank is decreasing by 0.4L per hour

<u>Phrase Into Algebraic Expression</u>
If a problem is correctly phrased, it should be easily translated into algebraic language by following simple and concrete rules.
We have the phrase:
<em>7 more than twice Jose's height.</em>
Usually, we first deal with products and divisions before sums and subtractions because of the natural order of mathematic operations.
In the given phrase, the '7 more' part is left to the end and we start with the 'twice' part because it's a product.
Since we are using the variable j for Jose's height, then twice Jose's height is 2j.
Now we finish the expression by adding 7: 2j+7
Thus, the translation to algebraic expression is: 2j+7
