Answer:
Amplitude:2, period:0.9 and phase shift:7
Step-by-step explanation:
In a function with the form y=Asin(Bx+c)+D, and given the function f(x) = –2sin (7x + 7), we get that:
A is the amplitude: 2
Period is given by 2pi/B, so 2pi/7=0.9
Phase shift is c: 7
-3x+4=15
-3x=15-4
-3x=11
x= -11/3
4(-11/3)-y= -19
-44/3-y= -19
-y= -19+44/3 multiply by (-1)
y=19-44/3
y=19•3/3-44/3
y=57/3-44/3
y=13/3
(x,y)=(-11/3, 13/3)
Answer:
a=6, b=-5
a=12, b=-5
Step-by-step explanation:
We have the equation
we will try to resolve for in terms of and
Then
Note that if the denominator is 0, then the division is undefined and therefore there would be no solution for x.
Then, the denominator is 0 if
.
Then, for the pairs
a=6, b=-5 and a=12, b=-5, there is no solution for x.
Answer:
6,9,7,10,8,11..
Step-by-step explanation:
If you notice that in the given sequence 6, 9, 7, 10, 8 the first element is 6 and then 3 is added in 6 to make it 9. Then 2 is subtracted from 9 which makes it 7 and then again 3 is added in 7 which makes it 10. After that again 2 is subtracted from 10 to make it 8. Now by following this method now we will add 3 in 8 which will give us the next item which is 11.
Thus the sequence we get is:
6,9,7,10,8,11...
