Answer:

If you set up the actual point, then you would have to it up like (x,y).

If you only have a (x) and then a coordinate, all you have to do is either add or subtract the (x) from the other (x) in (x,y).

Using translation concepts, the equation of g(x) is given as follows:

g(x) = -\frac{35}{x + 10} - 1

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For this problem, the parent function is given by:

f(x) = \frac{1}{x}

For a horizontal compression by a factor of 1/5, we have to find f(1/5x), hence:

g(x) = \frac{1}{\frac{1}{5}}x = \frac{5}{x}

For a vertical stretch by a factor of 7, we have to multiply by 7, hence:

g(x) = \frac{35}{x}

For a reflection in the y-axis, we have to find g(-x), hence:

g(x) = \frac{35}{-x} = -\frac{35}{x}

For a translation of 10 units left, we have to find g(x + 10), hence:

g(x) = -\frac{35}{x + 10}

For a translation of 1 unit down, we have to subtract one, hence:

g(x) = -\frac{35}{x + 10} - 1

Hank’s teacher asked him to verify that the product (y – 3)(y2 + 3y + 9) is a difference of cubes. He used the distributive prop
kicyunya [14]

Answer:

a = 9

Step-by-step explanation:

expand (y - 3)(y² + 3y + 9)

= y³ + 3y² + 9y - 3y² - 9y - 27

compare the coefficients of like terms with

y³ + 3y² + ay - 3y² - ay - 27

ay = 9y and - ay = - 9y ⇒ a = 9

9+3v is greater than or equal to 6
kondaur [170]

Answer:

If you take it in terms of integers,

9+3v may or may not be greater or equal to 6. It depends on the value of the variable you put in.

For eg:- if you substitute the value for v as 2 then 9+3x2=15 which is greater than 6 but if you put in -1 for v then you will get 9+3x(-1)=6
