Answer:
The other app my teacher told me to use to get the answer after i figure out says it is 1
Step-by-step explanation:
14 science fiction, 2 romance, 4 biography, 10 adventure...total of 30 books
P(biography) = biographies / total books = 4/30 which reduces to 2/15 <=
Part 1. x/1.6=3 (the slash is a fraction bar)
Part 2. x= 4.8
Answer:
The total number of cups of coffee is 12x - 3 ⇒ last answer
Step-by-step explanation:
- Madden and Jenn both worked at the coffee shop today
- Madden's total cups of coffee made is represented by f(x) = 7x - 4
- Jenn's total cups of coffee made is represented by g(x) = 5x + 1
- We want to write a function represents the total cups of coffee they
made together
∵ f(x) represents the number of cups of coffee that Madden made
∵ f(x) = 7x - 4
∵ g(x) represents the number of cups of coffee that Jenn made
∵ g(x) = 5x + 1
- To find the total cups they made together we will add the two
functions f(x) and g(x)
∵ f(x) + g(x) = (7x - 4) + (5x + 1)
- Add like terms
∴ f(x) + g(x) = (7x + 5x) + (-4 + 1)
∴ f(x) + g(x) = 12x + (-3)
-Remember (+)(-) = (-)
∴ f(x) + g(x) = 12x - 3
* <em>The total number of cups of coffee is 12x - 3</em>
Answer:
Domain: input values, independent variables
Range: output vales, dependent variables
Step-by-step explanation:
Think of it like a graph: the domain are the x-values and the range is the y-values. if you're doing a problem with time, the time will go on the x-axis and cannot be influenced by the y-values, but the y-vales are depending on what the x-values are (independent/dependent). for the input/output, usually when solving equations on a graph, you plug in the x-value and find the y-value. you're INPUTTING the x-value to receive the OUPUT.
