Given:

Required:
To calculate reference angle
Explanation:

Required answer:
Option B
Answer: Positive
Step-by-step explanation:
A scatter plot for speed and distance is created.
We know that distance = speed x time
Hence when speed increases , distance increases and similarly when speed decreases, distance decreases.
Thus if we plot on x axis distance, we find that x increases when y increases.
So we find that there is a strong positive relationship between the two variable
D=tS
where D= distance S=speed and T=time.
Since D varies directly as speed, we have positive relationship.
Hope this helps! :)
Answer:
x = 5, y = 6
Step-by-step explanation:
When you put these values in for x and y, the corresponding sides are congruent, also making the triangles congruent by the Hypotenuse-Leg Theorem.
I hope this helps! ☺
Solving:

Delete the first parentheses by the distributive property, with the distributive property, we multiply the '3' first, then resolve it and the second parentheses eliminate by changing the sign:

<span>Now, put the numbers with letter (incognito) to the right and numbers without letter to the left, changing the signal when changing sides.
