A text message plan coasts $7 per month pluse $0.46 per text. Find the monthly cost for x text messages.
1 answer:
p = 7 + 0.46x is the monthly cost for x text messages
<u>Solution:</u>
Given that, A text message plan costs $7 per month plus $0.46 per text
To find: Monthly cost for "x" text messages'
Let "x" be the number of text messages in a month
From given information,
text message plan cost per month = $ 7
Cost for 1 text = $ 0.46
Let "p" be the Monthly cost for "x" text messages
Then, we get,
p = text message plan cost per month + (Cost for 1 text)(number of text messages in a month)
Thus the monthly cost for x text messages is found

The function represents a reflection of
across the y-axis ⇒ 3rd answer
Step-by-step explanation:
Let us revise the reflection across the axes
- If the function f(x) reflected across the x-axis, then its image is g(x) = - f(x)
- If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x)
∵
∵ g(x) is the image of f(x) after reflection across the y-axis
- From the rule above reflection across the y-axis changes the sign of x
∴
∵
∵
∴
∴
The function represents a reflection of
across the y-axis
