The best answer is C) y=4.75 * cos(0.52x - 2.08) + 7.65
Unfortunately, the two only ways to solve this problem are to either graph all the options or plug in time values for x and see which agrees the most with the tide chart. Both are time-consuming, but I chose to graph each one with a graphing application.
Plugging in a few values for x confirms that C is the best function.
12pm (x=0)
y = 4.75 * cos(0 - 2.08) + 7.65
y = 5.334
2pm (x=2)
y= 6.5
4pm (x=4)
y=12.4
It is not a perfect representation, but the shape of the graph and closeness to the points given is the best of the four options provided.
We will see that the fourth statement:
"-0.3*|3 + 8x| = 0.9 has no solutions."
Is the true statement.
<h3>Which statement is true?</h3>
Here we need to see which statement regarding absolute value equations is true.
Here you can see that the fourth statement is:
-0.3*|3 + 8x| = 0.9 has no solutions.
Now, if you look at the left side of the above equation, the left side will always be negative, while the right side is positive, then the equation can't have a solution.
There is no value of x that makes that equation true, so it is true that the given equation has no solutions. This is the correct statement.

37.99/12= 3.165
So the price per pound would be $3.17
Answer:
Step-by-step explanation:
Thankfully this passes through the origin so we already know the y = mx + b resultingly has no y-intercept, so we only need to find slope as b is 0 and thus is redundant to say y = mx + 0.
Now all that's left to find is slope which is how much it rises by and how much it runs by. putting it in as rise over run
Using two points that are on the grid, which are given to us, (0, 0) and (-2, -3)
The rise, change in y, is a decrease of 3 units, written as -3
The run, change in x, is a change of 2 units, written as 2
Therefore
m = Slope = rise/run = -3/2
Because it intercepts the y axis (0, #) at 0 (0, 0) the origin meaning we dont write it in your slope-intercept formula, y = mx + b, is as follows
y = (-3/2)x
Hope this helps.
