Answer:
A. 72
Step-by-step explanation:
Determinant of a 2x2 matrix: ad - bc
In that case,
24(18) - 30(12)
432 - 360
72
And we have our answer.
The answer is
(x,y)= (2,0)
For points (x1,y1) and (x2,y2)
the slope is (y2-y1)/(x2-x1)
(3,4) and (6,6), slope is (6-4)/(6-3)=2/3
(4,-4) and (2,-7), slope is (-7-(-4))/(2-4)=(-7+4)/(-2)=-3/-2=3/2
for ax+by=c
slope=-a/b
3x+4y=12
slope=-3/4
Answer:
n = 23
23 minutes to walk to his friends house
Step-by-step explanation:
If Walter walks there 8 times, and it takes him 184 minutes, you have to divide 184 by 8. You will get 23 which is your answer.
