Answer:
Step-by-step explanation:
y - 1 + y = 4
2y - 1 = 4
2y = 5
y = 5/2
x = 5/2 - 1
x = 5/2 - 2/2
x = 3/2
(3/2, 5/2)
Answer:
7 million
Step-by-step explanation:
5.6 times 10^12 is 5.6 trillion
8 times 10^5 is 800,000
5.6 trillion/800,000 is 7 million
Answer:
56
Step-by-step explanation:
Arithmetic mean is simply the sum of the all the number present divide by the total number.
From the question, we obtained the following information:
The arithmetic mean = 5.6
Total number present = 10
Sum of the numbers =?
Arithmetic mean = sum of the numbers / total number
Sum of the numbers = arithmetic mean x total number
Sum of the numbers = 5.6 x 10 = 56
Answer:
The correct option is 3.
Step-by-step explanation:
The given equation is
It can be written as
Taking out the common factor form the parenthesis.
If an expression is defined as then we add to make it perfect square.
In the above equation b=6.
Add and subtract 3^2 in the parenthesis.
.... (1)
Add 32 on both sides.
The vertex from of a parabola is
.... (2)
If a>0, then k is minimum value at x=h.
From (1) and (2) in is clear that a=2, h=-3 and k=-32. It means the minimum value is -32 at x=-3.
The equation reveals the minimum value for the given equation.
Therefore the correct option is 3.
The slope of the line is 4.83 and the y-intercept is 51
<h3>How to determine slope and the y-intercept?</h3>
From the graph, we can see that the line of the best fit touches the y-axis at y = 51
This means that:
The y-intercept is 51
The slope is then calculated as:
m = (y2 - y1)/(x2 - x1)
Using the points on the line, we have:
m = (80 - 51)/(6 - 0)
Evaluate
m = 4.83
Hence, the slope of the line is 4.83
