5^(x+7)=(1/625)^(2x-13)
We move all terms to the left:
5^(x+7)-((1/625)^(2x-13))=0
Domain of the equation: 625)^(2x-13))!=0
x∈R
We add all the numbers together, and all the variables
5^(x+7)-((+1/625)^(2x-13))=0
We multiply all the terms by the denominator
(5^(x+7))*625)^(2x+1-13))-((=0
We add all the numbers together, and all the variables
(5^(x+7))*625)^(2x-12))-((=0
We add all the numbers together, and all the variables
(5^(x+7))*625)^(2x=0
not sure if this is right :/
The question given is incomplete, I googled and got the complete question as below:
You are a waterman daily plying the waters of Chesapeake Bay for blue crabs (Callinectes sapidus), the best-tasting crustacean in the world. Crab populations and commercial catch rates are highly variable, but the fishery is under constant pressure from over-fishing, habitat destruction, and pollution. These days, you tend to pull crab pots containing an average of 2.4 crabs per pot. Given that you are economically challenged as most commercial fishermen are, and have an expensive boat to pay off, you’re always interested in projecting your income for the day. At the end of one day, you calculate that you’ll need 7 legal-sized crabs in your last pot in order to break even for the day. Use these data to address the following questions. Show your work.
a. What is the probability that your last pot will have the necessary 7 crabs?
b. What is the probability that your last pot will be empty?
Answer:
a. Probability = 0.0083
b. Probability = 0.0907
Step-by-step explanation:
This is Poisson distribution with parameter λ=2.4
a)
The probability that your last pot will have the necessary 7 crabs is calculated below:
P(X=7)= {e-2.4*2.47/7!} = 0.0083
b)
The probability that your last pot will be empty is calculated as:
P(X=0)= {e-2.4*2.40/0!} = 0.0907
Solution: Below! ^^
Detailed explanation:
Hii! I'm sorry, I can't graph the line for you, but I'll try to give you the best possible explanation.
First, note that the question provides us with the info that the y intercept is -8. This is a very valuable piece of information!
This means that the line crosses the y axis (since it's the y intercept) at the point (0,-8). Plot it on the co-ordinate plane.
Next, this question also provides us with the fact that the slope of the line is 1/4. This is yet another valuable piece of information!
What this tells us is: from that point (0,-8), you need to go up 1 unit, then over 4, and so forth, until you obtain a line.

Answer:
8
Step-by-step explanation:
The distance or the length between two points can be computed using the formula:
X₁ = x-coordinate of first point
X₂ = x-coordinate of the second point
Y₁ = y-coordinate of first point
Y₂ = y-coordinate of the second point
When we right down the coordinates of a point, we always start with the X and then the Y.
(X,Y)
You have the following coordinates or points
Point 1: (-3,4)
Point 2: (5,4)
Based on that we have the following given:
X₁ = -3
X₂ = 5
Y₁ = 4
Y₂ = 4
Now we just fill in the formula:
