Start at -4 and go to the right 6 times on the number line and you should end up with 2
I assume that you want to know the temperature at a certain timing.
Well, you know that at 12:00 pm, the temperature was 12 F and that it decreases by a steady rate of 2 F each hour.
This means that at 1:00 pm, the temperature was 12-2 = 10 F
At 2:00 pm, the temperature was 10-2 = 8 F
At 3:00 pm, it was 8-2 = 6 F
.......and so on
You can follow this sequence to the timing you are looking for.
Answer:
2x - 6y
Step-by-step explanation:
(5x – 2y) – (3x + 4y)
5x - 2y - (3x + 4y)
Distribute the - sign
5x - 2y - 3x - 4y
Group like terms
(5x - 3x) + (-2y - 4y)
Combine like term
2x - 6y
Since f(-2) means that our x-value is -2, we can go to that position on the graph and slide up the y-axis to find the intersection this point has with the function graphed.
If I am correct the answer should be that the y value is 2!
