U do 21,800×12= AND THEN THATS ALL U DO GOOD LUCK!!!!!!
We know that we can take 4 out of (-16x + 8) [ we know this because we can divide 16 by 4 ( to get 4 ) and we can divide 8 by 4 ( to get 2 ) ]
we can factor out a 4 then from the parentheses to get 4(-4x + 2), but since we are multiplying by 1/4 we get
1/4(4)(-4x + 2), and since 1/4 * 4 = 1, our final answer is
-4x + 2
Answer:
r = 4.1231055
Step-by-step explanation:
So to do this, you need to find the distance between the two points:
(-7,1) and (1,3).
To do this, the distance or diameter (d) is equal to:
d = sqrt ((x2-x1)^2 + (y2-y1)^2)
In this case:
d = sqrt( (1 - (-7))^2 + (3 - 1)^2 )
d = sqrt( 8^2 + 2^2)
d = sqrt( 64 + 4)
d = sqrt( 68 )
The radius is half of the diameter, so:
r = 1/2 * d
r = 1/2 * sqrt( 68 )
r~ 4.1231055
Lets make an equation for the line first. The slope is 3 and the y intercept is -1, so we can make the equation y = 3x - 1. Then, to figure out what sign to use (<= or >= due to solid line in graph), we replace the = sign with one and see if a coordinate in the shaded area will furfill the inequality. If it doesn't, we know it needs the other inequality sign. If it does, we have found the correct inequality. So let's try y <= 3x - 1 with the coordinate (1,1). We try it, solve, and get 1 <= 2. So, the inequality for this graph is y <= 3x - 1.
