ANSWER
A.
EXPLANATION
The given equation is
This equation is already in the form:
This is called the slope-intercept form.
The slope is
and the y-intercept is 3.
The correct answer is A.
In a situation where the line is not given in the slope intercept form, then you must rewrite in this form before comparing.
Answer: C
The x row goes up every time by two and the y decreases by 4.
6-4=2 ect...
MARK THE BEST PLZ!!
There are 3 in. of snow on the ground when it begins to snow 0.5 in./h.
Initial depth of snow = 3 in.
it begins to snow 0.5 in./h. The constant rate of snow is 0.5. So slope = 0.5
Let x be the number of hours
y be the total depth of the snow
To frame linear equation we use y=mx+b
where m is the slope and b is the y intercept (initial depth of snow)
We know m=0.5 and b=3
Replace it in the equation
y = 0.5x + 3
The linear equation that represents the total depth of the snow(y), in inches, after x hours
is y= 0.5x + 3
Answer: A
Solution: To find the mean (average) of a data you add up all the data given and divide it by the amound of seperate data there is i.e there are 4 boys, boy a is 1.3m high, boy b is 1.5m high, boy c is 1.1m high and boy d is 2m high. To find the mean(average) you add up all the data (height) 1.3m + 1.5m + 1.1m + 2m = 5.9m, 5.9 is the total, to find the mean you divide the total by the amount of values (boys), there are 4 boys so you do 5.9/4 = 1.475m, so the mean is 1.475m
Basically All the data (regions) added up is 65,000 and there are five regions (values) so you divide 65,000 by 5 which is 13,000
