The point (17,−9) is translated to the point (6,2). Select the description of the translation.

zubka84 [21]

Answer:

11 up , 11 left

Step-by-step explanation:

Given

$(17, -9)$ to $(6,2)$

Required

Determine the translation rule

Considering the x coordinates.

From 17 to 6

6 is to the left of 17.

Using the translation rule:

$x = x' + b$

$17 = 6 + b$

$17 - 6 = b$

$11 = b$

$b = 11$

Hence: From 17 to 6 is 11 units left translation

Considering the y coordinates.

From -9 to 2

2 is at the top -9.

Using the translation rule:

$y = y' + b$

$-9 = 2 + b$

$-9 - 2 = b$

$-11= b$

$b = -11$

The negative value impies a upward translation.

Hence: From -9 to 2 is 11 units up translation

3x-x-5=2(x+2) -9 please help

irga5000 [103]

Answer:

infinite solutions

Step-by-step explanation:

Simplify 3x-x-53x−x−5 to 2x-52x−5.

2x-5=2(x+2)-92x−5=2(x+2)−9

2 Expand.

2x-5=2x+4-92x−5=2x+4−9

3 Simplify 2x+4-92x+4−9 to 2x-52x−5.

2x-5=2x-52x−5=2x−5

4 Since both sides equal, there are infinitely many solutions.

Infinitely Many Solutions

Find sin theta if theta is an angle in standard position and the point with coordinates (3, -4) lies on the terminal side of an

alisha [4.7K]

Answer:

$\sin \theta=-\frac{4}{5}$

Step-by-step explanation:

Given:

Angle is in standard position which means the starting ray is at the origin. The terminal side has coordinates (3, -4).

So, the 'x' value is 3 and 'y' value id -4.

Using Pythagoras Theorem, we find the hypotenuse.

Hypotenuse = $\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5$

Now, using the sine ratio for the angle, we have

$\sin \theta=\frac{Opposite}{Hypotenuse}\\\sin \theta=\frac{-4}{5}\\\sin \theta=-\frac{4}{5}$

Therefore, the value of $\sin \theta$ is $-\frac{4}{5}$ .

The value is negative as the point (3, -4) lies in the fourth quadrant and sine ratio is negative in the fourth quadrant,
