Answer:

3x sqrt(2x)

Step-by-step explanation:

sqrt(6x^2) * sqrt(3x)

We know that sqrt(a) sqrt(b) = sqrt(ab)

sqrt(6x^2*3x)

sqrt(18x^3)

sqrt(9*2 x^2 x)

sqrt(a) sqrt(b) = sqrt(ab)

sqrt(9) sqrt(x^2) sqrt(2x)

3x sqrt(2x)

3rd option: $-\frac{1}{2} < t \leq 3$ is the correct answer

Step-by-step explanation:

First of all, we have to observe the number line

Observing the number line we can see that the number -0.5 or -1/2 is not included in the solution as the circle on -1/2 is empty. An empty circle means that the number is not included in the solution.

While on the other side we can see that 3 has a filled circle which means 3 is included in the solution

This means that the solution might be:

$t>-0.5\\and\\t \leq 3$

By comparing the observation and the answer choices we can conclude that

3rd option: $-\frac{1}{2} < t \leq 3$ is the correct answer

He transformation function is (x, y) --> (x + 4, y - 2). The starting point is point A at (-5, 6). Step 1: A: (-5, 6) x: , y:

alex41 [277]

Given:

Rule of transformation is $(x,y)\to (x+4,y-2)$ .

Point = (-5,6)

To find:

The missing values in the given steps of transformation.

Solution:

Step 1: A: (-5, 6).

$x:-5,y:6$

Step 2: Substitute x and y into $(x+4,y-2):$

$(-5+4,6-2)=(-1,4)$

Step 3: Do the math:

Point A' is at (-1 ,4 ).

Therefore, the coordinates of the point (-5,6) after the transformation are (-1,4).
