Interchange the x and y and solve for the resulting y.
x = 4y^2 - 2
(x + 2) = 4y^2
(x + 2)/4 = y^2
+/- sqrt(x + 2)/2 = y
The graph of these two is below.
The original is in red
The inverse is in blue and green
The expression which represents Sherly's total income is 7e + 13n.
<h3>What is Cost Price?</h3>
The cost price represents the specific value that represents unit price purchased.
Here,
total pair of earrings = e
total pair of necklaces = n
Cost of 1 pair of earring = $ 7
Cost of 1 necklace = $ 13
earning from earring = 7e
earning from necklace = 13n
Total earning = earning from earring + earning from necklace
Total earning = 7e + 13n
Thus, the expression which represents Sherly's total income is 7e + 13n.

Answer:
21/128
Step-by-step explanation:
Area = L * w
L = 7/8
w = 3/16
Area = 7/8 * 3/16
Numerator of the answer = numerator * numerator = 3 * 7 =21
denominator of the answer = denominator * denominator = 8 * 16 = 128
Answer is 21 / 128. This fraction cannot be reduced.
The answer is A
