Step-by-step explanation:

x = -4y + 6

Now,

Substituting the value of x on 2x + 9y = 16, we get -.

2(-4y + 6) + 9y = 16

-8y + 12 + 9y = 16

y = 16 - 12

<h3>y = 4</h3>

Now,

Substituting the value of y on 2x + 9y = 16, we get -

2x + 9(4) = 16

2x = 16 - 36

2x = -20

<h3>x = -10</h3>

Hence,

The value of x is -10 and y is 4.

What is the common ratio between successive terms in the sequence? 2, –4, 8, –16, 32, –64, ... –2 –6 6 2
Nataly_w [17]

Answer:

-2

Step-by-step explanation:

You multiply each term by -2 to get the next term.

To find this for this sequence, divide the term on the right by the term on the left.

8 / -4 = -2              or          -4 * -2 = 8

-16 / 8 = -2             or         8 * -2 = -16

32 / -16 = -2           or         -16 * -2 = 32

-64 / 32 = -2           or         32 * -2 = -64

Make ratios.

12/16: 15/x

cross multiply

12(x) = 12x
16(15) = 240

12x = 240

isolate the x, divide 12 from both sides

12x/12 = 240/12

x = 20
