Perform the operation (9x^2+6x-7)+(-9x-5)

asambeis [7]

Answer:

9 $x^{2}$ -3x-12

9 $x^{2}$ +6x-7-9x-5

(Group liked terms)

9 $x^{2}$ +6x-9x-7-5

( subtract the numbers ) -7-5= -12

9 $x^{2}$ +6x-9x-12

( add similar elements ) 6x-9x=-3x

9 $x^{2}$ -3x-12

Line segment AB is one unit long. If point C cuts AB so that AC = 0.618, what is the ratio of AC to CB? a. 1 c. 1.32 b. 1.618 d.

Alecsey [184]

By the segment addition postulate,
AB = AC+CB
since C is somewhere between A and B

We know AC is 0.618 and AB = 1
CB = x for now

AB = AC+CB
1 = 0.618+x
1-0.618 = 0.618+x-0.618 ... subtract 0.618 from both sides
0.382 = x
x = 0.382

So CB is 0.382 units long

To find the ratio of AC to CB, divide the values
AC/CB = 0.618/0.382 = 1.618 (approximate to 3 decimal places)

Answer: Choice B) 1.618
