On a coordinate plane, triangle A B C is shifted 4 units to the right and 2 units up to form triangle A prime B prime C prime. I

zheka24 [161]

Answer:

(x, y) ⟶ (x + 4, y + 2)

Step-by-step explanation:

If you shift a point four units to the right, x ⟶ x + 4.

If you shift it up two units, y ⟶ y + 2.

If you combine the two shifts into one transformation, the rule becomes

(x, y) ⟶ (x + 4, y + 2)

A rectangle has vertices E(-4, 8), F(2, 8), G(2, -2) and H(-4, -2). The rectangle is dilated with the origin as the center of di

Marizza181 [45]

Answer:

The dilation on any point of the rectangle is $P'(x,y) = \frac{5}{2}\cdot P(x,y)$ .

Step-by-step explanation:

From Linear Algebra, we define the dilation of a point by means of the following definition:

$G'(x,y) = O(x,y) +k\cdot [G(x,y)-O(x,y)]$ (1)

Where:

$G(x,y)$ - Coordinates of the point G, dimensionless.

$O(x,y)$ - Center of dilation, dimensionless.

$k$ - Scale factor, dimensionless.

$G'(x,y)$ - Coordinates of the point G', dimensionless.

If we know that $O(x,y) = (0,0)$ , $G(x,y) =(2,-2)$ and $G'(x,y) =(5,-5)$ , then scale factor is:

$(5,-5) = (0,0) +k\cdot [(2,-2)-(0,0)]$

$(5,-5) = (2\cdot k, -2\cdot k)$

$k = \frac{5}{2}$

The dilation on any point of the rectangle is:

$P'(x,y) = (0,0) + \frac{5}{2}\cdot [P(x,y)-(0,0)]$

$P'(x,y) = \frac{5}{2}\cdot P(x,y)$ (2)

The dilation on any point of the rectangle is $P'(x,y) = \frac{5}{2}\cdot P(x,y)$ .

Which value of $y$ makes the equation $3y+8=7y+11$ true?

valentinak56 [21]

value of y which satisfies equation $3y+8=7y+11$ is $y= \frac{-3}{4}$ .

<u>Step-by-step explanation:</u>

We have , 3y+8=7y+11 . We need to find which value of y satisfies this equation 3y+8=7y+11 :

$3y+8=7y+11$

⇒ $3y+8=7y+11$

⇒ $(3y+8)-3y=(7y+11)-3y$

⇒ $8=4y+11$

⇒ $4y+11 = 8$

⇒ $(4y+11)-11 = 8-11$

⇒ $4y= -3$

⇒ $\frac{4}{4}y= \frac{-3}{4}$

⇒ $y= \frac{-3}{4}$

Therefore, value of y which satisfies equation $3y+8=7y+11$ is $y= \frac{-3}{4}$ .
