Answer: D
Step-by-step explanation:
So the problem is
4x-5=7+4y
solve for y
easy
minus 7 from both sides
4x-5-7=7-7+4y
4x-12=0+4y
4x-12=4y
divide both sides by 4
x-3=y
y=x-3
Answer:
Point A.
Step-by-step explanation:
We know that the temperature dropped 15 degrees, and that it was initially of 5°C. So, by midnight, the temperature will be of -10°C (5-15=-10).
We also know that the distance between points is of 5°C. So, the point that we have to mark is point A, which represents -10°C.
