nalin [4]

Answer:

1. 1/4 4 1 4 4 16 64 1024

2. 118

Step-by-step explanation:

1. 16 is obtained as 1024/64 = 16

before 16 goes: 64/16 = 4

before 4 goes: 16/4 = 4

before the second 4 goes: 4/4 = 1

before 1 goes: 4/1 = 4

before the third 4 goes: 1/4

2. From row 1 to row k, there are k² numbers (notice that rows finished in 1, 4, 9, etc., all perfect squares). 12² = 144, so 140 is on 12th row.

A number in row k is 2k less than the number directly below it. For example, 3 is on 2nd row, then is 2*2 = 4 units less than the number directly below it, which is 7.

The number above 140 is on the 11th row, then above 140 is 140 - 2*11 = 118.

Solve for x. -3x - 8 = 10

irinina [24]

Steps to solve:

-3x - 8 = 10

~Add 8 to both sides

-3x - 8 + 8 = 10 + 8

~Simplify

-3x = 18

~Divide -3 to both sides

-3x/-3 = 18/-3

~Simplify

x = -6

Best of Luck!

What is the y=Mx+b of this equation

Monica [59]

Answer:

$y = - 6x - 8$

Step-by-step explanation:

The y-intercept is where the line itersects the y-axis, which is the dark vertical line. This is -8 represented as the constant in the equation.

To find the slope, find the rise over run. Every time the line goes over 1 it goes down 6, so the slope would be -6.
