An equation is formed when two equal expressions. The cost per pound of wheat flour is $0.55 and the cost of per pound of rye flour is $0.55.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the cost of a pound of wheat flour be x and the cost of a pound of rye flour be y.
A baker purchased 13 lb of wheat flour and 14 lb of rye flour for a total cost of $14.85.
13x + 14y = $14.85
x = (14.85-14y)/13
A second purchase, at the same prices, included 15 lb of wheat flour and 12 lb of rye flour.
15x + 12y = $14.85
Substitute the value of x from the above equation and solve for y,
Substitute the value of y in any one of the equations formed,
13x + 14(0.55) = 14.85
13x = 7.15
x = 0.55
Hence, the cost per pound of wheat flour is $0.55 and the cost of per pound of rye flour is $0.55.

Answer:
linear function is always a straight line
As it is wave function
So it is non linear function
Option C
The explicit formula for the arithmetic sequence is
<em><u>Solution:</u></em>
Given that the arithmetic sequence is:
3, -3, -9, -15, -21, ...
To find: Explicit formula for the arithmetic sequence
<em><u>The nth term of an arithmetic sequence is given by:</u></em>
Where is nth term of sequence
n is the term's location
is the first term of sequence
d is the common difference between terms
In an arithmetic sequence, the difference between successive terms is constant. This means that we can move from any term to the next one by adding a constant value.
In the given sequence:
3, -3, -9, -15, -21, ...
d = difference between any two terms in sequence
d = -3 - (3) = -6
Substituting the values in above formula,
Thus the explicit formula to find any term in sequence is found
You have a lot of different questions here, I can help with the first part.
The range is the highest minus the lowest.
26 - 10 = 16
The mean is the result when you add them all up and divide by 10.
170 / 10 = 17
The median is the middle number in order.
The middle is at 15.
The mode is the number that shows up the most.
14 appears twice, every other number appears only once.
