Answer: negative, positive, zero, and undefined.
Step-by-step explanation: as x increases. The slope of a line can also be interpreted as the “average rate of change”.
Slope is calculated as the change in y over the change in x so you would need to do 5- (-5) which turns the negative sign to a positive making it 5+5=10 and the same thing with the 2s 2-(-2)=4 so the answer would be 10/4 or 5/2. Billy did the reciprocal.
According to the vertical angle rule we know that x is 40 degrees. The sum of all angles in a triangle make 180, so the sum of x, 60, and the third angle is 180. x is 40 so the third angle is 180-60-40 which is 80 degrees. y is an adjacent angle, which means that the sum of y and 80 degrees is 180. 180-80 is 100, so y is 100 degrees.
2 weeks = 14 days
10 / 14 = 0.71428571428
0.71428571428 * 31 = 22.1428571429
The town received about 22 inches of rain.
If you include the 2 weeks, then it would be 32 inches of rain.
Hope this helps!
So I did this:
y=x +2
y=3x-4
I used the first equation to plug into the second equation.
x+2= 3x -4
I subtracted 3 from both sides so I get
-2x+2=-4
So I subtract 2 from both sides so I get
-2x=-6
I divide -2 on both sides and so I get
x=3
Then I plug the x into either equation. I did the first equation.
y=3+2
y=5
So x=3 and y=5
