How do i find the middle top number of a 2x2 matrix?

Step-by-step explanation:

the awnser is 04

So if we don't unnecessarily confuse ourselves by taking  bases, a 2x2 matrix will always have rank 2 unless one row or column is a scalar multiple of the other*, in which case it will have rank 1. (and also it'll have rank 1 if you have a row or column of zeroes, and rank 0 if it's the zero matrix).

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
