Answer:
Slope:-1/4 y-int: 3
Step-by-step explanation:
You can you the formula y1-y2/x1-x1 or you can look at it and find out if that makes sense
To solve this, we have to complete the square of
To do this with halve the and get rid of the x, then get rid of the power on , and then put them all in brackets, and the square the bracket, like so:
becomes
However does not equal
If we expand we get instead.
So to make it equal, all we do is subtract 1.
So when we complete the square of , we get
---------------------------------------------------------
So becomes:
x + 1 = ±√6
x = -1 ± √6
______________________________
Answer:
x = -1 ± √6
Answer:
Equivalent equation of is
And the number of sides does a polygon have is, n =9.
Step-by-step explanation:
Given:
The sum of the interior angles, 's' in a n-sided polygon can be determined
using the formula is: .....[1]
where n is the number of sides.
We can write the equivalent equation of [1]
Divide both sides by 180;
Simplify:
Add 2 to both sides of an equation:
Simplify, we get;
......[2]
Now, to find the value of n ;
Given: s =1260°
Substitute this value in [2] we get;
or
n = 7+2 =9
Therefore, the number of sides in a polygon is, n=9
The correct answer is 3.
The formula for the law of sines is the following:
P/sin P = Q/sin Q = R/sin R
So, if you break these up into two different equations, you will have:
P/sin P = Q/sin Q and P/sin P = R/sin R
To solve, get P alone on one side of the equation by multiplying the other side by sin P:
P = Q sin P/sin Q and P = R sin P/sin R
When you look at the answers, you'll see that the second equation is an option.
Answer:
The answer is C
