When hav epoins (x1,y1) and (x2,y2)
slope is (y2-y1)/(x2-x1)
(-3,4) and (5,-1)
slope=(-1-4)/(5-(-3))=-5/(5+3)=-5/8
slope=-5/8
Answer:
On average, the land moved 0,14 cm each year.
Step-by-step explanation:
To know how much did, on average, the land move, we should divide the total number of cm over the total number of years:
x=24.8 cm/175 years
x=0,1417 cm each year
If we divide years over cm we will get x in years each cm, which is wrong.
Because the problem asks for the answer rounded to the hundredths place:
x= 0,14 cm each year
Answer:
The answer is 14
Step-by-step explanation:
14x2=28
14x3=42 so the greatest common factor is 14
We need the cross product of the two vectors.
a x b
=<2,-2,-3> x <3,2,2>
=
i j k
2 -2 -3
3 2 2
=<-4+6, -(4+9), 4+6>
=<2,-13,10>
The second vector is obtained by reversing the direction, namely <-2,13,-10>
Thus the two vectors are <2,-13,10> and <-2,13,-10>.
Answer:
17. xy + z = 51
18 yz - x = 18
21. 5z + ( y - x ) = 20
22. 5x - ( y2 - 4x ) = -10
23 . x2 + y2 - 10z = 70
24. z3 + ( y2 - 4x ) = 1
25. y + xz / 2
26 .3y + x2 / z = 30
Step-by-step explanation:
17.(6 x 8)+3=
48+3=51
18.(8 x 3)- 6 =
24 - 6 = 18
21. 15 + ( 8 - 3 )
15 + 5=
20
22 .30 - (64 - 24)=
30 - 40=
-10
23. 36 + 64 - 30
100 - 30
70
24. 9 + (16 - 24 )=
9 + -8 =
1
25. 8 + 48 / 2
56 / 2
28
26. 24+ 36/3
60/3=
30
