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:

$T =|5| =5$

$T' =|-5| =5$

The sum of 43 and z is equal to 72.98. Enter the equation that represents the description.

Irina-Kira [14]

sum is an answer to an addition problem, so we have to add 43 and z. z+43=72.98

Subtract 43 on both sides.

z=29.98

You want to create a piece of

emmainna [20.7K]

After six and half hours for studio A and after eight hours for studio B, the total costs of both studios will be the same.

Rate is a measure or quantity measured against another quantity or measure which is the ratio between two related quantities in different units

It is given that you want to create a piece of pottery at an art studio. The total cost is the cost of the piece plus an hourly studio fee. The costs at two studios are shown.

Studio A: $8 per hour.

Studio B: $6.50 per hour.

Multiply both together. That is,

8 x 6.5 = $52

The two cost will be the same at $52. By that time,

Studio A will be six and half hours.

Studio B will be eight hours.

Therefore, after six and half hours for studio A and after eight hours for studio B, the total costs of both studios will be the same.
