The solution set of a linear system whose augmented matrix is [a b c d] is the same as the solution set of Ax = d, where A = [a

Charra [1.4K]

Answer:

True

Step-by-step explanation:

First statement

[a b c | d][x]

[a b c]x=d

ax+bx+cx=d

Second statement

Ax=d

Given that A = [a b c]

[a b c]x=d

ax+bx+cx=d

Then, they are going to have the same solutions

If 3^2x+1=3^x+5 what is the value of x?

atroni [7]

Did you mean this? 3^2x+1=3^x+5 => 3^(2x+1) = 3^(x+5)? If so, then 2x+1 is necessarily equal to x+5, so that 2x+1=x+5. Thus, x = 4 (answer).

Those parentheses are not optional; they must be part of your problem statement and solution.
