- Choice A
- Choice D
- Choice E
- Choice F
So basically everything but choices B and C are functions.
====================================
Explanation:
- A. This is a function as there are no repeated input x values. Each input (x) leads to exactly one output (y).
- B. This is not a function. We have the input 2 lead to more than one output (1 and 4 at the same time)
- C. This is not a function. Similar to choice B, we have multiple outputs for a given input. In this case, x = 20 has more than one output.
- D. This is a function. Any x input will produce only one y output. When graphed, it passes the vertical line test.
- E. This is a function. This graph passes the vertical line test. It is not possible to draw a vertical line through more than one point on the blue curve, so that's what I mean by "passing the vertical line test".
- F. This is a function. At any given hour (x), there is exactly one temperature (y) possible. The thermometer is not going to produce multiple readings at any one specific moment in time.
A= 153.9 mm sq
Formula for area is pi times radius squared
It would be $1.50 because if the soda's $1 then subtract it and divide that by the quantity.
What does the spinner look like
Answer:
The equation is
y = $ 12.35 x
Step-by-step explanation:
Cost of one bag of rocks = $ 12.35
Let there are x bags of rocks, so that the total cost is y.
So, the cost of 1 bag = $ 12.35
cost of x bags = $12.35 x
The total cost is
y = $12.35 x
It is the equation of a straight line which passes from origin and the slope is 12.35.
