<span>7x - 2 = 2y
7x = 2y + 2
so
</span>7x = 2y + 2<span>
3x = 2y - 1
----------------subtract
4x = 3
x = 3/4
</span>7x - 2 = 2y
7(3/4) - 2 = 2y
21/4 - 2 = 2y
21/4 - 8/4 = 2y
13/4 = 2y
so
y = 13/4 * 1/2
y = 13/8
answer
<span>(3/4, 13/8)</span>

Answer:
Q(18) is a mathematical representation of the weight in pounds of a puppy after 18 months.
Q(30) = 27.5 ; This means that the weight of puppy after 30 months will be 27.5 pounds
Step-by-step explanation:
Given the expressions :
Q(18)
Q(30) = 27.5
Function Q gives a puppy's weight in pounds as function of its age in months
What does each expression represent in this situation?
A function is generally represented in the form a(x) ;
Hence, Q(18) is a mathematical representation of the weight in pounds of a puppy after 17 months
Q(30) = 27.5 ; This means that the weight of puppy after 30 months will be 27.5 pounds. 27.5 is the result of working out the function Q at 30.
