Given that Kimora’s cell phone company charges her $35 a month for phone service plus $.05 for each text message sent.
Kimora's cell phone bill for one month is $52.
We need to determine the number of text messages Kimora sent for one month.
Also, we need to write and equation and solve it.
<u>The equation:</u>
Let x denote the number of text messages Kimora sent for one month.
Thus, the equation is given by
Therefore, the equation for the number of text messages Kimora sent for one month is
<u>Solving the equation:</u>
We need to solve the equation
Subtracting both sides of the equation by 35, we get;
Dividing both sides of the equation by 0.05, we get;
Therefore, the number of messages sent is 340.
Answer:
The correct option is the last one.
Step-by-step explanation:
To transform the graph of into
the following steps are fulfilled:
1) Move the graph 2 units to the right:
Let then
Notice that the cut point has been moved to x = 2.
2) Reflect on the x axis:
To reflect a graph on the x-axis we do Then
3) Stretch according to factor 2.
For this we do
Then we have
4) Move up the graph in two units:
We do
Then
These steps coincide with those listed in the last option. Therefore the correct option is the last one.
"Translate 2 units on the right, reflect on the x-axis, stretch according to the factor 2 and translate 2 units"
