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:

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%.**
