Answer:
7/3
Explanation:
The slope of the line is equal to the rise/run, or in other words, the number of units the line travels upwards over the number of units the line travels to the right.
We can identify the slope using any two points on the line. Here, we can use the two points that are marked on the picture. The second point is 7 units above the first and 3 units to the right of the first, so the slope of the line is equal to 7/3.
Another way to calculate the slope of the line is the use this formula:
(y2-y1)/(x2-x1)
The first point is at the coordinate (1,-4) and second point is at the coordinate (4,3). When we plug these two coordinates into the equation, we get this:
(y2-y1)/(x2-x1)
->(3-(-4))/(4-1)
When we simply the fraction, we would get 7/3 and that would give us the slope.
I hope this helps!
To find the number of days, divide the total swam by the average:
Days = 48 / 3.2 = 15
They swam for 15 days.
Answer:
Diagram 1
Step-by-step explanation:
This diagram does not represent a function because the x value 6 is outputting 2 different y values, 4 and 6. This goes directly against the rules of a function.
Answer:
x = 0 or x = 5/2
Step-by-step explanation:
Solve for x over the real numbers:
x^2 sqrt(2 x - 5) = 0
Split into two equations:
x^2 = 0 or sqrt(2 x - 5) = 0
Take the square root of both sides:
x = 0 or sqrt(2 x - 5) = 0
Square both sides:
x = 0 or 2 x - 5 = 0
Add 5 to both sides:
x = 0 or 2 x = 5
Divide both sides by 2:
Answer: x = 0 or x = 5/2
