As written here, both choices B and C represent proportional relationships:
... B. y = 12x
... C. y = 3x
_____
One key to a proportional relationship is that when one variable is zero, so is the other. This will not be the case for selections A and D.
Answer:
x = 6
Step-by-step explanation:
→ Rewrite equation
x + 3 = 9
→ Minus 3 from both sides
x = 6
If a function is undefined, this usually means that the
value is 1 / 0.
Since tan theta is the reciprocal of cot theta.
Therefore:
cot theta = 1 / 0 = 1 / tan theta
Taking the right side:
1 / 0 = 1 / tan theta
Rearranging so that tan theta is in the numerator:
tan theta = 0
I ma taking algebra 2 also so i can help any time
Answer: Choice C
(4, 18)
=========================================
Explanation:
One point shown on the graph is (2,9)
If we double each x and y coordinate, then
We go from (2,9) to (4,18)
Plotting this point on the graph will be on the same line as the other points.
Or you could note that y/x = 9/2 = 18/4 = 4.5
