Step-by-step explanation:
13x < 18x -24 -6
13x < 18x -30
13x - 18x < -30
-5x < -30
x = 6
The slope would be - 1/2 !!
you would number the x and y values of the coordinates.
( -2 , 5 ) ( -6 , 7 )
x1. y1. x2. y2
then do the formula that gives you the slope y2 - y1 / x2 - x1
this gives you:
7 - 5 / -6 - (-2) = 2/ -4 (simplify) -1/2
so this would give you m= -1/2
Answer:
7 1/2 x - 3/4 y
Step-by-step explanation:
From F.S 1, consider this series : 8, 1, 8, 8, 64, 64*8.
Again, consider the series 2, 1/4, 1/2, 1/8, 1/16, 1/(8*16). Clearly, the difference of the 6th and the 3rd term is different for them. Insufficient.
<span>From F.S 2, let the series be </span><span><span>a,b,ab,a<span>b2</span>,<span>a2</span><span>b3</span>,<span>a3</span><span>b5</span></span><span>a,b,ab,a<span>b2</span>,<span>a2</span><span>b3</span>,<span>a3</span><span>b5</span></span></span><span>. Now we know that </span><span><span>a<span>b2</span>=1</span><span>a<span>b2</span>=1</span></span>. The required difference =<span><span><span>a3</span><span>b5</span>−ab=ab(<span>a2</span><span>b4</span>−1)=ab[(a<span>b2</span><span>)2</span>−1]</span><span><span>a3</span><span>b5</span>−ab=ab(<span>a2</span><span>b4</span>−1)=ab[(a<span>b2</span><span>)2</span>−1]</span></span><span>= 0.Sufficient.</span>
