Find the location of A' given that A is (7, 1).
SSSSS [86.1K]

Answer:

We conclude that the location of A' is: A'(6, 1)

Step-by-step explanation:

Given

  • A(7, 1)

To determine:

The location of A'

Translation Rule:

As we have to translate 1 unit left, meaning we need to subtract 1 unit from the x-coordinate of point A(7, 1) to determine the location of A'.

In other words, the translation rule is:

A(x, y) → A'(x-1, y)

as

A(7, 1)

so

A(7, 1) → A'(7-1, 1) = A'(6, 1)

Therefore, we conclude that the location of A' is: A'(6, 1)

Which of the following is being constructed in the image?
madam [21]
The answer is C, a perpedicular bisector. The distances of the mark along the given line are equidistance. Where the x is located, where the two dashes would intersect is where a 90 degre angle to the line would pass through.

For two weeks, Gabrielle raised money by selling magazines. She raised $72 during the second week, which brought her total to $1
Mila [183]

Ok so if Gabriel’s total is 122$ and she made 72$ The second week your equation would be 122= 72x  now if you subtract 72 from both sides that cancels out the 72 leaving you with 50=x.

Let f(x) = x² + x - 6 and g(x) = 3x - 6, what are f ⋅ g and f/g. state the resulting function and it's domain.
Lady bird [3.3K]

Answer:

f \cdot \: g  = 3 {x}^{3}  - 3 {x}^{2} - 24x  + 36

Domain: All real numbers

\frac{f}{g} =  \frac{x + 3}{3}

Domain: x≠2

Step-by-step explanation:

The given functions are

f(x) =  {x}^{2}  + x - 6

and

g(x) = 3x - 6

f \cdot \: g = f(x) \cdot \: g(x)

This implies that:

f \cdot \: g  = (3x - 6)( {x}^{2}  + x - 6)

We expand to get:

f \cdot \: g  = 3x ( {x}^{2}  + x - 6) - 6( {x}^{2}  + x - 6)

We expand to get:

f \cdot \: g  = 3 {x}^{3}  + 3 {x}^{2} - 18x - 6{x}^{2}  -  6 x  + 36

We group like terms to get:

f \cdot \: g  = 3 {x}^{3}  - 3 {x}^{2} - 24x  + 36

This is a polynomial function, the domain is all real.

Also;

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

\frac{f}{g} =  \frac{ {x}^{2} + x  - 6 }{3x - 6}

Factor to get:

\frac{f}{g} =  \frac{(x - 2)(x + 3)}{3(x - 2)}

Cancel common factors:

\frac{f}{g} =  \frac{x  + 3}{3}

The domain is all real numbers, except numbers that will make the denominator zero.
