You are fishing at Lake hilton and intend to catch two types of fish: salmon and trout. Local fishing laws allow you to catch at most 10 salmon and at most 8 trout. You intend to capture more salmon than trout. You need to catch at least 5 fish for the family dinner tonight. Let x = the number of salmon and y = the number of trout. Which of the following inequalities are needed to represent this system? Choose all that apply. *
y > x
x ≤ 8
x + y > 5
y ≤ 10
y ≥ 0
x ≤ 10
x > y
x ≥ 0
x + y ≥ 5
y ≤ 8
Answers
Answer:
x+y >= 5
y<=8
x<=10
x>y
Step-by-step explanation:
x+y is greater or equal to 5 because you need at least 5 for dinner.
y is less than equal to 8 because the fishing laws state you can't have more than 8 trout.
x is less than equal to 10 because the fishing laws state you can't have more than 10 salmon.
x>y because you intend to catch more salmon than trout

A line has a slope of 3, is increasing, and passes through the point (2,7). What is its y-intercept?
Answers
The y-intercept is 1.
First, we need to put this into point slope form which is y-7=3(x-2)
Next, multiply using the distributive property. y-7=3x-6
Lastly, we want to get y by itself so add 7 on both sides. y=3x+1.
Using the slope intercept form, y=mx+b where b is the y-intercept, we can see that the line will cross the y-axis at 1.
Hope this helps✨❤️
The y-intercept of the line is 1
Using the slope - intercept relation :
y = bx + cc = Intercept; b = slope point (2,7)
Substituting the values into the relation :
7 = 3(2) + c
7 = 6 + c
c = 7 - 6
c = 1
Therefore, the y-intercept of the line is 1.

Answer:
area is 100m bc u do 10 times 10
Step-by-step explanation:
Answer:
139.27 meters squared
Step-by-step explanation:
So what you're doing is calculating the square's area and half of the circle's area.
The square's area is 100m^2 since 10*10=100
For the circle part, you use πr^2. You know the diameter of the circle, and radius is half of the diameter, so 10/2=5.
π*5^2 = 78.54 m^2
Since you have half of a circle you divide this by 2.
39.27
Finally you add your two areas together
100+39.27=139.27 meters ^2

The stock of Company A lost $2.55 throughout the day and ended at a value of $57.45. By what percentage did the stock decline?
Answers
Given:
Loss = $2.55
Value of stock after loss = $57.45
To find:
The percentage by which the stock decline.
Solution:
We have,
Loss = $2.55
Value of stock after loss = $57.45
Value of stocks before loss = Value of stock after loss + loss
= $57.45 + $2.55
= $60
Now,
[tex]\text{Percentage by which the stock decline}=\dfrac{\text{loss}}{\text{initial value}}\times 100[/tex]
[tex]\text{Percentage by which the stock decline}=\dfrac{2.55}{60}\times 100[/tex]
[tex]\text{Percentage by which the stock decline}=4.25%[/tex]
Therefore, the stocks of the company declined by 4.25%.
