Answer:

c. (x -6, y +8)

Step-by-step explanation:

We can tell which answer to choose by looking at the change in the y-coordinate. Point Y is (4, -4). Point Y' is (-2, 4). The new y-coordinate has been translated upward by ...

4 -(-4) = 8 . . . units

That is, y' = y +8. This matches choice C.

The translation of Y(4, -4) to Y'(-2, 4) is described by ...

(x, y) ⇒ (x -6, y +8)

Y(4, -4) ⇒ Y'(4 -6, -4 +8) = Y'(-2, 4)

Find the area. If applicable, leave the answer in simplest radical form. Helpp

Answer:

The area is $28\ m^{2}$

Step-by-step explanation:

I assume that the figure is a square

The area of a square is equal to

$A=b^{2}$

where

b is the length side of the square

In this problem we have

$b=2(\sqrt{7})=2\sqrt{7}\ m$

substitute in the formula

$A=(2\sqrt{7})^{2}$

$A=28\ m^{2}$

Plz help me with this i do not understand math stuff

Zarrin [17]

Answer: Pink choice: y= -6x -2

Step-by-step explanation:

In order to be parallel, the slope must be the same. You find the slope as the number or fraction connected to x. <em>("co-efficient" of x in math talk)</em>

In the given equation, that is -6. (So that knocks out the first two choices)

The other thing to look at is the y-value of the given coordinate,(-1,4)

<em>(The y-value is the second number in the coordinate (x.y) is the pattern)</em>

and compare it to the the last number in the equations in the choices and Here the Yellow choice has y= -6x + 4 so this line can't pass through the coordinate given, because +4 in this equation is where the line crosses the y-axis. ("y-intercept" in math talk) So yellow choice is out!

The attachment shows what the graphs of the choices look like.

The black line is the correct answer. The given coordinate (-1,4) is the labeled red spot. The blue line is the given equation. (You can see where it "intercepts the y-axis on the +3) And the green line also has the -6 slope, but misses the point and intercepts the y-axis at 4.)

I hope the diagram and explanation helps you understand better. It can be confusing.
