Answer:
C. -0.7
Explanation:
Given the equation:
First, distribute the bracket on the left-hand side:
The number that makes the given expressions equivalent is -0.7.
The correct choice is C.
The y-intercept represents the average cost, in dollars per pint, of all the raspberries Ethan bought. Therefore, option B is the correct answer.
Given that, Ethan bought 3 pints of raspberries for $5 per pint and x pints of blueberries for $3 per pint.
The average is (15 + 3x)/(3+x) per pint.
We need to find what quantity will be represented by the y-intercept of the graph.
<h3>How to find the y-intercept of the graph?</h3>Since the y-intercept always has a corresponding x-value of 0, replace x with 0 in the equation and solve for y. On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.
Now, the graph of y=(15 + 3x)/(3+x)is given below.
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept(s): (−5,0)
y-intercept(s): (0,5)
So, the y-intercept represents the average cost, in dollars per pint, of all the raspberries Ethan bought.
Therefore, option B is the correct answer.
