Answer:
The slope is 5/-2.
Step-by-step explanation:
Slope is y1-y2 over m1-m2 (rise over run). The first ordered pair is -2 (m1) and 11 (y1). We then subtract the second ordered pair (4 (m2) and -4 (y2)) from the first.
11 - (-4) = 11 + 4 = 15
-2 - 4 = -6
Remember, slope is rise over run (y over x), so the slope is 15/-6. Now, we must simplify. 15/-6 = 5/-2
Dean went wrong because he thought that slope was run over rise (x over y). If he had switched the two numbers, his answer would have been correct.

Answer:
x = 8
Step-by-step explanation:
The sum of the exterior angles is 360 degrees
12x+62+ 66+ 77+59 = 360
Combine like terms
12x+264 = 360
Subtract 264 from each side
12x+264-264 = 360-264
12x =96
Divide by 12
12x/12 = 96/12
x=8

Answer:
Divide the diameter by 2 and insert for radius in the equation
Step-by-step explanation:
To find the area of a circle, we can use the equation <em>A=pir^2 </em>or <em>area=pi*radius squared.</em>
The radius is half of the diameter, so just divide the diameter by 2 and plug it into the equation.
Hope this helps!
