I will mark brainliest if you are correct Tell whether x and y are in a proportional relationship. If so, find the unit rate.
Let y be the temperature x hours after midnight. The temperature is 60∘F at midnight and decreases 2∘F every 12 hour.

No they are not in a proportional relationship

Step-by-step explanation:

answer is nooo

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
