<h3>The cost of purchasing baby chicks at $4.50 per chick represents proportional relationship</h3>
<em><u>Solution:</u></em>
in a proportional relationship, one variable is always a constant value times the other.
y = kx
Where, k is a constant
<em><u>Option 1</u></em>
The cost of purchasing hay for $26 a bale with a delivery charge of $30
Cost = $ 26 a bale + 30
This does not forms a proportional relationship
<em><u>Option 2</u></em>
The cost of purchasing baby chicks at $4.50 per chick
Let "x" be the number of chicks
Therefore,

Thus, this forms a proportional relationship
<em><u>Option 3</u></em>
The cost of purchasing fencing at $29 a linear foot with an installation fee of $300
cost = $ 29 a linear foot + 300
This does not forms a proportional relationship
<em><u>Option 4</u></em>
The cost of renting a backhoe for $79 per hour with a non-refundable deposit of $300
cost = $ 79 per hour + 300
This does not forms a proportional relationship
The given expression becomes undefined when y=5 or y = -3. The answer is option D.
Step-by-step explanation:
The value of the given expression becomes undefined when the denominator equals 0.
Hence to find the value of y which makes the expression undefined, we can equate the value of the denominator to zero and solve it .
Step 1
Equate the denominator to 0.
y^{2} - 2y -15 = 0
Step 2
Solve the above equation to get the value of y.
y^{2} - 2y -15 = 0
=> (y-5)(y+3) =0 [ Roots of the quadratic equation]
=> y = 5 or y = -3.
Hence when y = 5 or y = -3 the denominator becomes 0, which makes the expression (2y+7)/0 and hence it is undefined.
