Answer:

A = (1/2)(y2 - y1)(x3 - x1) (This corresponds to Answer D)

Step-by-step explanation:

Let (y2 - y1) represent the length of the base and (x3 - x1) represent the height. Then, according to the formula for the area of a triangle of base b and height h, the area in this case is:

A = (1/2)(y2 - y1)(x3 - x1) (This corresponds to Answer D)

The transformations and their respective descriptions are:

A. (x, y) ⇒ (3x, y) implies horizontal stretch by a scale factor of 3

B. (x, y) ⇒ (x+3, y) implies translation 3 units right

C. (x, y) ⇒ (x, 3y) implies vertical stretch by a factor of 3

D. (x, y) ⇒ (x, y+3) implies implies translation 3 units up

E. (x, y) ⇒ (3x, 3y) implies dilation with a scale factor 3

<h3>What is Translation?</h3>

Translation is an algebraic transformation of a shape by moving the vertices some units along the x or y axis.

When a shape is translated it may move to a new position depending on the orientation of the translation.

Analysis:

For A, the x coordinate was transformed three times its initial value stretching it horizontally.

For B, the x coordinate moved 3 units further away from its initial value making the new value x+3 and y remaining the same.

For C, the y coordinated was transformed to a value three times what it was, making it to be stretched vertically, since the y-axis is a vertical axis.

For D, the y coordinate was moves 3 units away from its initial position making it to be translated up, since 3 is positive.

For E, both coordinates were stretched 3 units as much as their original value making the shape to dilate.

Draw the graph of functions that passes through (0.5,3), (1.5,4), and (2.5,1)

puteri [66]

Answer:

We have to plot a graph of the function that passes through the points (0.5,3), (1.5,4), and (2.5,1).

Clearly the graph passing through the three points will form a triangle with these coordinates. we could clearly see our graph from the figure attached to the answer.

The graph passing through two given points form a line,through three points it form a triangle and through four given points it form a quadrilateral.

Sabe-se que EF = xcm , GH = (x + 6) cm , RS = 16 cm e NP = 28 cm . Sabendo que EF ,GH , RS ,e NP São, nessa ordem, segmentos pro

Marysya12 [62]

Answer:

The value of x is 8 .

Step-by-step explanation:

It is known that EF = x cm , GH = (x + 6) cm , RS = 16 cm and NP = 28 cm . Knowing that EF ,GH , RS , and NP are, in that order, proportional segments, determine the value of x .

As EF, GH, RS and NP are in proportion

So,

EF : GH = RS : NP

$\frac{x}{x+6}=\frac{16}{28}\\\\7 x = 4 (x + 6)\\\\7 x = 4 x + 24 \\\\3 x = 24 \\\\x = 8$
