The graph of y = StartAbsoluteValue x EndAbsoluteValue is transformed as shown in the graph below. Which equation represents the
iogann1982 [59]

Using translation concepts, it is found that the equation of the transformed function is:

y = |x + 3| - 2.

<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 in it's definition.

The absolute value function is given by y = |x|, and has vertex at (0,0). After the transformations, the function has vertex (-3, -2), which means that:

  • It was shifted 3 units to the left, hence x -> x + 3.
  • It was shifted 2 units down, hence y -> y - 2.

Thus, the equation of the function is now given by:

y = |x + 3| - 2.

Express the situation as a system of two equations in two variables. Be sure to state clearly the meaning of your x- and y-varia
expeople1 [14]

Answer:

9 TV ads and 20 radio ads

Step-by-step explanation:

He has $37,000 to spend. He has to sum that amount of money between the TV and radio ads. Each TV ad costs $3000 while each radio ad costs $500, so the equation that represents that is 37000 = 3000x  + 500y  

The same happens with the amount of voters he needs to reach, the equation is 130000 = 10000x + 2000y

The system that represents this is

\left \{ {{3000x+500y=37000} \atop {10000x+2000y=130000}} \right.

And the augmented matrix is

\left[\begin{array}{cc|c}3000&500&37000\\10000&2000&130000\end{array}\right]

First we divide the first row by 3000 and the second by 10000:

\left[\begin{array}{cc|c}1&1/6&37/3\\1&1/5&13\end{array}\right]

Then we multiply the second row by (-1) and we add the first row:

\left[\begin{array}{cc|c}1&1/6&37/3\\0&-1/30&-2/3\end{array}\right]

Now we multiply the second row by -30:

\left[\begin{array}{cc|c}1&1/6&37/3\\0&1&20\end{array}\right]

Finally, to the first row we add the second one multiply by (-1/6):

\left[\begin{array}{cc|c}1&0&9\\0&1&20\end{array}\right]

So, x = 9 and y = 20

That means 9 TV and 20 radio ads will contact 130,000 voters using the allocated funds

<span>On the day of a child's birth, a sum of money is to be invested into a certificate of deposit (CD) that draws 6.2% annual interest compounded continuously. The plan is for the value of the CD to be at least $20,000 on the child's 18th birthday.  
</span>
let \ P \ = Initial \ amount 

Let \ R \ = Annual \ Interest  \ as \ a \ decimal 

Let \ x \ = Solution 

x=Pe^r^t 

Let \ variable \ a = 20,000 \ , \ r = 0.062 \ and \ t = 18 
<span> 
</span>Use \ Substitution \ to \ solve 

The substitution<span> method is used to eliminate one of the variables by replacement when solving a system of equations
</span>
P= \dfrac{20,000}{e0.062.18} = \dfrac{20,000}{e1.116} = \dfrac{20,000}{3.0526} = 6,551<span>
