12 3 4 5 6 7 8 9 10 time remaining 46: 34 what is the rule for the reflection? ry=x(x, y) → (–y, –x) ry=–x(x, y) → (–y, –x) ry=x(x, y) → (y, x) ry=–x(x, y) → (y, x

Solution:

Keep in mind:

When a point (a,b) is reflected across a line , y=x the coordinate of new point after reflection becomes (b,a).

Also , when  point (a,b) is reflected across a line , y= -x the coordinate of new point after reflection becomes (-b,-a).

So, option (B)  r ,(Line, y=–x),Preimage → (x, y) → (–y, –x)→image,  and Option (C) r (Line, y=x),Preimage→ (,x, y) → (y, x) →Image, are true options describing the rule of reflection across  lines, y=x,and  y= -x.

The answer is B. Just took the test.

Step-by-step explanation:

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
