The first term of the sequence is -3.
According to the formula each next term will be obtained by multiplying the previous term by 2.
So, next terms will be:
Second term = 2 x First Term = 2 x (-3) = - 6
Third term = 2 x (-6) = -12
Fourth term = -24
Fifth term = -48
Sixth term = -96
So, the sequence will be:
-3, -6, -12, -24, -48, -96 ...
Answer:
Given equation:
when we complete the square , we take half of the value of 8 , then square it, and added to the left sides, we get;
∵8 is the value
Notice that, we add this both sides so that it maintains the equality.
then;
[ ]
Simplify:
The number must be added to complete the square is,
First to figure out the problem you need to distribute the 3 and the 4. You get, 3x-3-8=4+4x+5. Now you need to combine the coefficients. After doing this you will have 3x-11=9+4x. Now to get x by itself you need to subtract 3x from both sides. You will have -11=9+x. Then you subtract 9 from both sides and you end up with x=-20
3(x-1)-8=4(1+x)+5
3x-3-8= 4+4x+5
3x-11=9+4x
-3x -3x
-11=9+x
-9 -9
-20=x
Answer:
10
Step-by-step explanation:
Answer:
x=47, y=68
Step-by-step explanation:
Add the two equations. Then we get
-y=-68
y=68
Substituting the value of y in the first equation,
8x-6(68)=-32
8x-408=-32
8x=376
x=47
