Answer:
Debra’s rate is 3 Words Per Minute (WPM)
Explanation:
In order to find a rate, you need to put the unit (words) over the time (minutes):
27words/9minutes
You then have to simplify this expression:
3words/1minute
You can further simplify this to “3 words per minute” or “3 WPM”
y/9 +5 =0
subtract 5 from each side
y/9 = -5
multiply both sides by 9
y = -5 * 9
y = -45
Argon because when you compare the place values, 0.78 which is the amount of nitrogen and 0.93, the amount of argon in air. 0. Is the same so move to the next number, 0.7 and 0.9. 9 is the largest number so 0.93, ( Argon) is more
Answer:
- x-intercept (12.5, 0)
- y-intercept (0, -5)
Step-by-step explanation:
The slope of the line is ...
... (change in y)/(change in x) = (-3 -(-5))/(5 - 0) = 2/5
The y-intercept is given: (0, -5).
The slope-intercept form of the equation can be written from this information as ...
... y = (2/5)x - 5
Solving this for y=0 (to find the x-intercept), we have
... 0 = (2/5)x - 5
... 5 = (2/5)x
... 5·(5/2) = x = 12.5
So, the x-intercept is 12.5, and the y-intercept (given) is -5.
