What is the y-coordinate of point D after a translation of (x, y) → (x + 6, y – 4)?

fiasKO [112]

The y - coordinate of D after a translation is 1

Explanation:

The point D after a translation is given by $(x, y) \rightarrow(x+6, y-4)$

The y - coordinate of the point D is 5.

Now, we shall determine the value of the y - coordinate of D after the translation $(x, y) \rightarrow(x+6, y-4)$

Let us consider the y - coordinate of D' and D

Thus, we have,

$y-4=5$

Subtracting both sides by 4, we get,

$y=1$

Thus, the y - coordinate of D after a translation is 1

What is x if x/5 =-9

Leona [35]

Answer:

x = -45

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Multiply 5 to both sides:

(x/5) * 5 = (-9) * 5

x = -9 * 5

x = -45

x = -45 is your answer.
