Answer:
3.14
Step-by-step explanation:
Radius = 1
1^2 times pi = 1 pi
1 pi is about = 3.14
Use slope formula:
m = (y2-y1) / (x2-x1)
-1/4 = 6-2 / 1/2 - x
-1/4 = 4 / 1/2 - x
-1(1/2 - x) = 4(4)
-1/2 + x = 16
x = 16 1/2 or 33/2
5x +7=12 is an example of an open equation because it contains a pronumeral (x)
ANSWER
1a)
The given system of equation is:
and
We make x the subject in equation (2) to get;
We put equation (3) into equation (1) to get;
We expand the bracket to get,
This implies that,
This statement is false.
Hence the system has no solution.
1b)
Let us write the two systems in the slope-intercept form;
For the first equation, we have
Thus implies that,
For the second equation, we have:
We can see that, the two equations are parallel since they have the same slope.
Also the two equations will never meet since they have different y-intercepts.
Hence the system has no solution.
300 miles.
1 inch is 200 miles
half an inch is 100 miles
200 plus 100 equals 300 miles
