Hello!
Find the coordinate where x = -1:
At x = -1, y = 1, so the coordinate is (-1, 1).
Find the coordinate where x = 2:
At x = 2, y = -2, so the coordinate is (2, -2).
Find the rate of change between the points using the slope formula:
Plug in the coordinates above:
Simplify:
Thus, the rate of change between the points is -1.
G^2+2=0,
g^2=-2
g= sqrt-2, not possible.
3g+1=0
3g=-1
g=-1/3
9 cannot be equal to zero for the last one.
Answer:
20
Step-by-step explanation:
Percentage of item shopped =60%.
No. of item shopped = 12
Then,
⇒ 60% of total item =12
Total item = 12/60*100 =20.
Therefore, number of item in the list = 20.
Answer:
D) 5
Step-by-step explanation:
Since 2x = x+5, we have x = 5.
That would be the number of permutations of 3 from 10.
= 10P3 = 10! / 7! = 10*9*8 = 720
