6.50-2.25=x
x is how much Jackson's lunch was
Well, in the first one, 2 degrees below zero is -2 degrees, and then it says that it dropped 14 degrees, which means it dropped -14 degrees, so to know the total amount it dropped you would just have to add -2 plus -14 which is -16 degrees, so your answer for the first question would be the last answer, -16 degrees.
For the second question, just know that whenever a negative number is BY ITSELF in parentheses, that means it is used like a positive number in the equation. So (-12) automatically becomes 12. Now, since the problem is asking for a SUM, (the answer to an ADDITION problem; when you add instead of subtract), you would turn that minus symbol to a plus symbol, and add normally to get your final answer; 30 + 12 = 42. To check if this is correct, just type in <span>30 – (–12) to a calculator and you'll get the same answer! :D
Hope this helps! :3</span>

Answer:
y = 20 + 40x
Step-by-step explanation:
You can see that where x = 0, y = 20, which gives us the y intercept. We can also see that for each step on the grid, x increases by 0.5, and y increases by 20. Which means that y increases at a rate of 20/0.5 - or 40 - with respect to x.
