Graph a triangle (STU) and reflect it over the y-axis to create triangle ST'U'.

lukranit [14]

The x-coordinates of $\triangle S'T'U'$ will be the negation of the x-coordinates of $\triangle STU$

The line segment from S to the y-axis equals the line segment from S' to the y-axis. Similarly, the line segment from T to the y-axis equals the line segment from T' to the y-axis

See attachment for $\triangle STU$ and $\triangle S'T'U'$

In order to solve this question, I will make the following assumptions.

Assume that the coordinates of $\triangle STU$ are

$S = (4,5)$

$T = (5,9)$

$U=(3,8)$

Refer to attachment for illustrations

(1) Reflect $\triangle STU$ over y-axis and describe the transformation

To reflect $\triangle STU$ across the y-axis, the following rule must be followed

$(x,y) \to (-x,y)$

This means that:

$S = (4,5) \to S' = (-4,5)$

$T = (5,9) \to T' = (-5,9)$

$U=(3,8) \to U'=(-3,8)$

The description of the transformation is as follows:

Notice that the signs of the x-coordinates $\triangle STU$ and $\triangle S'T'U'$ of both triangles are different.

In other words, if the x-coordinate of one is positive, then the other will have a negative x-coordinate; and vice versa.

(2) Compare the segments and the line of reflection

To reflect across the y-axis means that the reflecting line is the y-axis, itself.

The distance between a point to the y-axis is the absolute value of the x-coordinate.

So, the distance between S and the y-axis is:

$S = |4| = 4$

The distance between S' and the y-axis is:

$S' = |-4| = 4$

We can conclude that the two line segments are equal.

This is the same for other point T and T' because of the formula used above.

From T and T' to the y-axis is:

$T =|5| =5$

$T' =|-5| =5$

Cleopas has $96 in his bank account. He spends $34 on new football gloves. Which of the following describes the current value in

Sauron [17]

Answer:

The second option

-34 dollars in a negative direction from $96

Step-by-step explanation:

So its -34

And when subtracting it Moves in a negativ direction

so -34 in a negative direction from 96

Please help me, im about to cry cause im so confused. Please explain this to me

eduard

$\bold{2.5y=5x-5 }$

$\bold{y=\dfrac{5x-5}{2.5} }$

$\bold{y=\dfrac{2.5(2x-2)}{2.5} }$

$\bold{y=\dfrac{\cancel{2.5}(2x-2)}{\cancel{2.5}} }$

$\bold{ y=2x-2 }$

X-6y-7=0. What is equation in general form.

son4ous [18]

Answer:

y=1/6x-7/6

Step-by-step explanation:

-6y = -x + 7

y = x/6 - 7/6

This is assuming you mean in standard form.

Also, you may have to write it as 'y=1/6x-7/6'
