In the above statement, the number 3 is a common factor between the two terms in the statement, 3x and 3y. We can divide 3 into both numbers evenly. This is also called “factoring<span> out” 3. Finding the common factor allows us to apply the </span>Distributive Property<span> to the statement.
Hope this helps</span>
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.
Answer:
B
Step-by-step explanation:
In the parenthesis with x it up or down on the y axis, and then after the function is what where after or before the origin the line starts on the x-axis.
Answer:
y = -2x + 4
Step-by-step explanation:
To write an equation in slope-intercept form, y = mx + b, we need to find the slope (m) and the y-intercept (b).
✔️Slope (m) using two pairs of values, (0, 4) and (1, 2):
Slope (m) = change in y/change in x
m = (2 - 4)/(1 - 0) = -2/1
m = -2
✔️y-intercept is the value of y when x = 0. Therefore, fromm the table, when x = 0, y = 4.
y-intercept (b) = 4
✅Write the equation by substituting m = -2 and b = 4 into y = mx + b:
Thus,
y = -2x + 4
