There is no number line given, so I will use the "keep change flip" method.
Hope this helps.
You can use the definition of logarithm to evaluate x and get the solution of the given equation.
The solution to the given equation is given by: Option A: x= -3
<h3>What is the definition of logarithm?</h3>
If a raised to power b equates to c, then we can say that logarithm of c with base a is b.
Or symbolically:
<h3>How to use definition of logarithm to solve the given equation?</h3>
We can reverse the definition of log to get back to representation in powers.
Thus,
I used the fact that
Thus, the solution of given equation is given by Option A: x = -3

<h3>
Answer: Irons cost = $310</h3>
==============================================================
Explanation:
r = cost of irons
w = cost of woods
These costs are in dollars. They are some positive real number.
The irons cost $90 more than the woods, so r = w+90
The total cost is $530, leading to r+w = 530
We can apply substitution to solve for w
r+w = 530
(r) + w = 530
(w+90) + w = 530 .... replace r with w+90
w+90+w = 530
w+w+90 = 530
2w+90 = 530
2w+90-90 = 530-90 ... subtract 90 from both sides
2w = 440
2w/2 = 440/2 .... divide both sides by 2
w = 220
A set of woods golf clubs cost $220
This must mean
r = w+90
r = 220+90
r = 310
The set of irons cost $310
---------------------
Check:
(woods cost)+(irons cost) = (220) + (310) = 530
This confirms the answer.
Answer:
Following are the solution to the given question:
Step-by-step explanation:
For point a:
For point b:
For point c:
Once again, we have k = 2 though with Chebyshev discrepancy of witness numbers in the same number of standard deviations off mean = at least 75 percent.
99 degrees warmer because since -27 a negative number you have to add 27 to get to 0 so Alaska is then 72 degrees which is a positive number so you add 72+27 and get 99
