For a rectangle with length 3x+4 and perimeter of 10x+18, what is the width of the rectangle
Answer:
The answer to this question is B
Step-by-step explanation: By simplifying both equations to a x = ? both equations lead up to x = -7. Inversely, you can multiply both sides of the first equation by -3 and get the same equation as the second equation.
A function is a relationship that each input (element of the domain) is paired with exactly one output (element in the range).
In function notation, f(x), the “x” is the input and the entire “f(x)” represents an output.
That means the last two options are wrong. They’re purposely switched up in what they say.
The correct answer is the second one, because that one is saying “each input will be paired with exactly one output.”
