B&D seems to be correct, but as we do not know what operation is the black circle you could argue that none of the above is correct.
y = -2x + 2
slope = -2
perpendicular slope = 1/2 (-ve inverse of the slope)
coordinates (0, 1)
y - y1 = m(x -x1)
y - 1 = 1/2(x - 0)
y = 1/2x + 1
We have that
2x²<span>-3x-6=0
using a graph tool----------> to resolve the second order equation
see the attached figure
the solution is
x=-1.137
x=2.637
therefore
a=-1.137
b=2.637
so
</span>(a+2)*(b+2)-----------> (-1.137+2)*(2.637+2)--------> 0.863*4.637---> 4
the answer is 4
i think the answer might be 3
The answer is 4) 140.
If we closely examine the pattern of the series, we see that after a number is subtracted by a value, it is multiplied by the same value, and then it moves on to the next natural number.
- 10 - 2 = 8
- 8 × 2 = 16
- 16 - 3 = 13
- 13 × 3 = 39
- 39 - 4 = 35
The next step, according to the pattern, would be to multiply 4.
