Answer:
-1/2
Step-by-step explanation:
The slope of a line is given by
m = (y2-y1)/(x2-x1)
= (1-2)/(3-1)
= -1/2
The slope is -1/2
Let's create a table, and use arbitrary values of x between -3 and 3 (if the solution is not in this interval, we can use another one later). If we call:
We want to find the x's for with f(x) = 0
This is the table:
And now we can evaluate f(x) in each value of x to complete the table:
The table is:
If we use this values and plot them in the cartesian plane.
We get:
And now if we plot a line that connects the points, we get the graph of the quadratic equation:
Since the problem ask us to find the value of x for which f(x) = 0, we can see both in the table and in the graph that this value is x = 2
Answer: 3^2 k^10
Step-by-step explanation:
Answer:
36
Step-by-step explanation:
Let the original quantity of marbles of the bag be y.
y=36
15.8% would round to 16%
If the number after the decimal point is 5 or greater you round the 5 up to a 6. If it had been less than a 5 it would have rounded down to 15%.
