Answer: 34 degrees
Step-by-step explanation:
The starting temperature was -5 degrees at 5am, and after two hours, the temperature was 34 degrees at 7am. The temperature increased by 39 degrees, how did we get this answer?
You add -5 and 39
-5 + 39 = 34
A tip for adding negatives:
When you get a problem similar to -5 + 39, you can actually flip them around if you need an easier understanding. So it would be 39 - 5. Both equations still equal 34 as long as you keep the values of each number!
Answer:
Variable "m"
Step-by-step explanation:
Hello!
The equation
is perhaps the most used equation when representing a line. The parts of the equation:
- y = output, y-value, ordinate...
- m = slope, rate of growth, rise over run...
- x = input, x-value, abscissa...
- b = y-intercept
____________________________________________
Let's use an example: y = 2x + 5
We want to find the y-value when x is 2.
To solve, simply plug in 2 for x:
- y = 2(2) + 5
- y = 4 + 5
- y = 9
So, the coordinate when x is 2 is (2,9), remember that coordinates are written in (x,y) format.
