Answer:
(x, y) = (-2, 7), (0, -1), (3, -13), (-1, 3)
Step-by-step explanation:
To fill in the y-values, you need to put the x-value in the equation and evaluate.
<u>for x=0</u>
y = -4(0) -1 = -1
<u>for x=-1</u>
y = -4(-1) -1 = 4 -1 = 3
__
To fill in the x-values, we can solve for x and then do as we did above.
y = -4x -1
y +1 = -4x . . . . add 1
-(y +1)/4 = x . . . divide by -4
<u>for y=7</u>
x = -(7 +1)/4 = -2
<u>for y=-13</u>
x = -(-13+1)/4 = -(-12/4) = 3
__
Then the table is ...
If you wanna divide 9's on your fingers, its really easy...
Example: If you wanna do 3x9 you hold up your 10 fingers and put down your fourth finger... it would look like your saying 36, and that is your answer.
Another example: If you wanna do 6x9 you hold up your 10 fingers and put down your 7th finger... It would look like you are saying 63 and that is your answer.
I hope this helps, tell me if you have any questions.<span />
Answer:
X=20
Step-by-step explanation:
The 3 angles all add up to 180º because they are a straight line.
3x + 80 + 2x = 180
5x + 80 = 180
5x + (80-80) = 180-80
5x = 100
5x/5 = 100/5
X=20
Hope this helps!
