Answer:
20
Step-by-step explanation:
6^2 = 36 (the exponent only applies to the 6, not the entire parentheses)
(76-36) = 40
(6 - 4) = 2
40 / 2 = 20
Answer:
x = -7
Step-by-step explanation:
This is an exponential equation.
We need to take log(or ln) of both sides and use logarithm property to solve this.
So, let's take ln of both sides, so we have:
Now, we will use this property shown below to further simplify:
So, we now have:
The value of x is -7
The common denominator is 3 because
example: 3x4= 12 and 3x3= 9
If the bracelets was 5$ each it could be p = 5b
Answer:
x1 = -1, x2 = 2, x3 = -4, x4 = 0
If it wants everything in terms of what x4 equals then the system is inconsistent since x4=0
Step-by-step explanation:
Once you have it in that reduced row echelon form it's super easy.
The first column is x1, second is x2 and so on.
The first row says x1 + 0x2 + 0x3 + 0x4 = -1, or in other words x1 = -1. You can do this for all the rows.
this does mean that x4 = 0, so if the instructions are saying it wants everything n terms of x4, you can't do that so it is inconsistent.
