this makes no sense, so imma guess for u.
C
Sandwiches are $5.25 Bowls are $3.50
4x+5y=38.50
3x+9y=47.25
Answer: 11/24
Convert 3/8 to 9/24
Convert 1/12 to 2/24
Add them together to get 11/24
If I did a poor job explaining I can help more in the comments.
Answer:
The equation for the proportional relationship is y = 2.8x.
If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate.
Answer:
The average slope is 8.
Step-by-step explanation:
Let <em>f</em> be defined on the closed interval [a, b]. The average slope of <em>f </em>between a and b is the quotient
average slope = 
To find the average slope of the function
on the interval [-1, 3] you have to evaluate your function in the interval and then divide by the interval.
So,

The average slope is
