Find the area of the rectangle when the length is 3 yards and the width is 9 yards.
The area is length x width, which is 27 yards (squared).
which part of the coordinate plane has negative x and negative y values?
Quadrant 3
-8(11)
-88 (negative times positive equals NEGATIVE)
-3c+y-2c-2y
-5c-1y or -y-5c
1/2 (4x+2y-2)
2x+1y-1
What is the name of the perimeter of a circle?
Circumference
what is it called when a point is on the x or y axis?
intercept
-60 divided by 12
-5 (Positive and Negative equals a NEGATIVE)
Simplify this:
x+2y+4-2x+3y-2
-x+5y+2
0.5(100x+50y+1)
50x+25y+0.5
y=2/3x-2
Slope= 2/3
Y-intercept= -2
