Answer:

y=55 when x is 33

Step-by-step explanation:

Use the direct variation formula:

\frac{y}{x} =k  or \frac{y}{x} =\frac{y}{x}

Insert the given values:

\frac{15}{9}=\frac{y}{33}

To simplify the equation, cross multiply:

15(33)=9(y)\\\\495=9y

Isolate the variable. Divide both sides by 9:

\frac{495}{9} =\frac{9y}{9} \\\\55=y

Therefore, when x is 33, y is 55.

:Done

Triangle ABC below is reflected across the y-axis and then translated 1 unit right and 2 units down.
hodyreva [135]
Any point with coordinates (x, y) reflected across the y-axis is going to have the opposite x value that it did before.
You should be able to find the coordinates yourself for part a. (you didn't provide the original ones so I can't help you there)
Here is the "rule" for a reflection across the y-axis:
(x,\ y)\rightarrow(-x,\ y)
And when we go 1 unit to the right and 2 down, that's the same as
(x,\ y)\rightarrow(x+1,\ y-2)

Combining those into one rule is pretty simple, Use our result for the first in the second and we would get (-x+1,\ y-2), so the rule is
\boxed{(x,\ y)\rightarrow(-x+1,\ y-2).
Part A is asking for the coordinates after the reflection (x, y) ⇒ (-x, y).
Part C is asking for the coordinates after the full translation ⇒ (-x+1, y-2)
