Answer:

The answer is MQR= 48 degrees

Step-by-step explanation:

I got this answer from process of elimination. The first option was 48 degrees so I divided 48 by 3 and got 16 then I applied to (2x + 16): (2(16)+16) and got 48 which comfirmed my answer. Also I took the test and it was right so I know its correct.

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)

Assume that y varies directly with x, then solve.<br>if y=-6.6 when x=9.9, find y when x=6.6​
vladimir1956 [14]

Answer:

y = - 4.4

Step-by-step explanation:

Given that t varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = - 6.6 when x = 9.9 , that is

- 6.6 = 9.9k ( divide both sides by 9.9 )

k = \frac{-6.6}{9.9} = - \frac{2}{3}

y = - \frac{2}{3} k ← equation of variation

When x = 6.6, then

y = - \frac{2}{3} × 6.6 = - 2 × 2.2 = - 4.4
