Which vector best describes the translation below?

Nimfa-mama [501]

<h3>Answer: Choice A) <9,0></h3>

Explanation:

Focus on one of the points in the figure on the left. Let's say we go for the upper left corner point (-7, 4)

Notice it moves to the corresponding image point (2,4). It has shifted 9 units to the right to follow the translation rule $(x,y) \to (x+9, y)$ . We've added 9 to the x coordinate, and the y coordinate stays the same.

This notation can be shortened to <9, 0>

In general, the notation $(x,y) \to (x+a, y+b)$ is shortened to the translation vector notation $< a, b >$ . In this case, a = 9 and b = 0.

How do you find the slope (m) and the y-intercept for (0,-4), (5,-4)?

navik [9.2K]

Answer:

In order to find the slope (m), and the y-intercept of this coordinate pair, you must complete rise over run.

This is represented by y2-y1, x2-x1. This can be represented like so:

-4-0 = -4

5--4 = 9

Here, we have concluded that our slope is -4/9.

Now, we must convert this into point slope form. Point slope form is y-y1=m(x-x1). This will look like this in our situation:

y+4=-4/9(x-0)

To solve, distribute the -4/9 first, which will leave you with:

y+4=-4/9x+0

Now, subract the 4 to both sides of the equation.

Our final answer looks like: y=-4/9-4.

<em>SLOPE: -4/9</em>

<em>Y INTERCEPT: -4 </em>

What is halfway between 6 and -10

Anastasy [175]

We can find the number that is halfway between 6 and -10 by finding their average.

Number = (-10+6)/2 = -4/2 = -2

Therefore, the number halfway between them is -2.

Please help me:

lora16 [44]

Answer:

6 units

Step-by-step explanation:

This coordinate is a three dimensional coordinate, which involves positive and negative x,y, and z axis.

The y axis is from left to right, i.e from negative to positive.

So 6 unit left is = -6 but it explains moving left .

Thank you

Ed needed to extend the string on his kite. The current string was eight and three fourths feet. He cut a piece of string that m

Pani-rosa [81]

The new length of the string is (13 + 1/4) feet, then the correct option is the last one (counting from the top)

<h3> What is the new length of the string?</h3>

We know that the current string was (8 + 3/4) feet in length. Then they add another piece that measures 4.5 feet.

The new length of the string is given by the addition of the above two lengths, we will get:

L = (8 + 3/4) feet + 4.5 feet

We can rewrite the second length as a mixed number:

4.5 = 4 + 1/2 = 4 + 2/4

Replacing that we get:

L = (8 + 3/4) ft + 4.5 ft

= (8 + 3/4) ft + (4 + 2/4) ft

= (8 + 4) ft + (3/4 + 2/4) ft

= 12ft + 5/4ft = 12ft + (4/4 + 1/4)ft = (13 + 1/4)ft

The new length of the string is (13 + 1/4) feet, then the correct option is the last one (counting from the top).
