Answer:
<h2>24</h2>
Step-by-step explanation:
Given the following logarithmic expressions
, we are to find the value of 
Substituting x = a³, y = a⁷ and z = a⁻² into the log function
we will have;

Hence, the value of the logarithm expression is 24
Answer:
x = -1, y = -4
Step-by-step explanation:
Let's solve our system of equations by substitution.
y = 5x + 9y = −x + 3
Step: Solve = 5x + 9 for y:
y = 5x + 9
Step: Substitute 5x + 9 for y in y = −x + 3:
y = −x + 3
5x + 9 = −x + 3
5x + 9 + x = −x + 3 + x (Add x to both sides)
6x + 9 = 3
6x + 9 + −9 = 3 + −9 (Add -9 to both sides)
6x = −6
6x/ 6 = −6/6(Divide both sides by 6)
x = −1
Step: Substitute −1 for x in y = 5x + 9:
y = 5x + 9
y = (5)(−1) + 9
y = 4(Simplify both sides of the equation)
So our answers are y = -4 and x = -1.
Answer:
I believe the one that is selected is correct.
Step-by-step explanation:
1/5k - 2/3j and -2/3j + 1/5k
If you switch the subtraction to addition, 2/3 becomes negative, while 1/5 stays the same.
The median is the middle of a list of numbers from least to greatest.
I will set up the numbers from least to greatest for you.
5, 6, 6, 8, 9.
To determine the median, cross out the smallest number with the largest number until you can no longer do so.
5, 6, 6, 8, 9.
6, 6, 8.
6.
Your median is 6.
I hope this helps!
