Given the translation T(3, -1), translate the ordered pairs (-3, 6) and (9, -8). choices: (0, 7) and (6, -7) (0, 5) and (12, -9)

anastassius [24]

Answer:

The translated ordered pairs are $P_{1}'(x,y) = (0, 5)$ and $P_{2}' (x,y) = (12, -9)$ .

Step-by-step explanation:

Vectorially speaking, a translation is defined by the following formula:

$P'(x,y) = P(x,y) + T(x,y)$ (1)

Where:

$P(x,y)$ - Original point.

$P'(x,y)$ - Translated point.

$T(x,y)$ - Translation vector.

If we know that $P_{1}(x,y) = (-3, 6)$ , $P_{2} (x,y) = (9, -8)$ and $T(x,y) = (3, -1)$ , then the translated points are, respectively:

$P_{1}'(x,y) = (-3, 6) + (3,-1)$

$P_{1}'(x,y) = (0, 5)$

$P'_{2}(x,y) = (9,-8) + (3, -1)$

$P_{2}' (x,y) = (12, -9)$

The translated ordered pairs are $P_{1}'(x,y) = (0, 5)$ and $P_{2}' (x,y) = (12, -9)$ .

QUESTION 16 Which of the numbers below are related in the same way as 3259 and 2? A. 5789 and 29 B. 3174 and 6 C. 2749 and 4 D.

dalvyx [7]

Answer:

Option (B)

Step-by-step explanation:

Relation between two numbers 3259 and 2,

3259 → 3 × 2 + 5 - 9 = 2

Now we will check the relation in the given options,

Option (A).

5789 → 5 × 7 + 8 - 9 = 34

Option (B).

3174 → 3 × 1 + 7 - 4 = 6

Option (C).

2749 → 2 × 7 + 4 - 9 = 9

Option (D).

9047 → 9 × 0 + 4 - 7 = -3

Therefore, Option (B) shows the same relation.

Let fx=3x+2 then f(3)<br><br> Simple functions

eimsori [14]

$f(x)=3x+2\\f(3)=3(3)+2\\f(3)=9+2\\f(3)=11$

We substitute x = 3 in the equation and get the y-value.
