Answer: The number can be used to express the change in temperature= -14
Step-by-step explanation:
Given: The temperature in evening dropped by
.
Thus, the change in temperature = 
Since the temperature in evening is dropped or decreased , thus in integers the change in temperature = 
Therefore, the number can be used to express the change in temperature= -14
Answer:
Yes, this is a function
Step-by-step explanation:
You know this because it passes the vertical line test.
I hope this helps!
So hmm notice the picture below
thus

so, is clearly not 0, so it has to be 1.74
Answer:
<u>Slope = 3</u>
Step-by-step explanation:
Slope is calculated as the "Rise/Run" of a straight line. The Rise is the change in the value of y, or the amount y changes per change in x. Run is the change in the x value. A line with a run of 3 and a rise of 9 is calculated as:
Rise/Run = 9/3 or 3
This means that the value of y will increase by 3 for every increase of 1 in the value of 3.
Slope in "m" in the slope-intercept form of a straight line equation: y = mx + b
The line y = 3x + 2 tells us the it has a slope of 3 and intercepts the y axis at x = 2.
Example points (y = 3x + 2)
(0,2)
(1,5)
(4,14)
Note that y changes by 12 when x changes by 4. Rise/Run = 12/4 or 3.
56.8 * 7 = 397.6
He travel 397.6 miles in all.
