Answer:
1. C: y = 3x - 5
2. B: y = -3x - 9
Step-by-step explanation:
1.
y = 3x + 9; (2, 1) (parallel)
(x₁, y₁)
y - y₁ = m(x - x₁)
y - 1 = 3(x - 2)
y - 1 = 3x - 6
+1 +1
-------------------
y = 3x - 5
----------------------------------------------------------------------------------------------------------
2.
y = (1/3)x - 6 ; (-3, 0) (perpendicular)
(x₁, y₁)
y - y₁ = m(x - x₁)
y - 0 = -3(x - (-3))
y - 0 = -3(x + 3)
y - 0 = -3x - 9
+0 +0
----------------------
y = -3x - 9

The answer in simplest form is [tex]20\frac{30}{11}[/tex] .
What is fraction in simplest form?When the numerator (top) and denominator (bottom) of the fraction do not have any common factors, the fraction is said to be in its simplest form. When the top and bottom of a fraction are whole numbers that are coprime to one another, the fraction is said to be in its simplest form.Any fraction can be easily found in its simplest form. By dividing both the numerator and denominator by the greatest common factor that entirely divides them, we need to simplify the fraction's numerator and denominator. Both the numerator and the denominator should still be whole numbers after division. Reducing fractions is another name for this process of simplifying fractions.Given fraction is [tex]5*4\frac{6}{11}[/tex].
So we convert the mixed fraction into an improper fraction to calculate further.
[tex]4\frac{6}{11} =\frac{50}{11}[/tex]
Next, we calculate the above fraction given in the question
[tex]5*\frac{50}{11}[/tex] = [tex]\frac{250}{11}[/tex]
So now we convert obtained improper fraction to mixed fraction which is its simplest form,
[tex]\frac{250}{11} = 20\frac{30}{11}[/tex]

The graph of y = 2x^2 - 8x + 7 is identical to the graph of y = a(x-h)^2 + k$ for some real numbers $a, h, k$.
What is the value of $k$?
The form:
y = a(x-h)^2 + k
Is the vertex form of the quadratic equation, by finding the vertex, we conclude that k = -1.
How to get the value of k?For any quadratic equation of the form:
y = a*x^2 + b*x + c
With a vertex (h, k), we can rewrite the equation as:
y = a*(x - h)^2 + k
And the value h of the vertex is given by:
h = -b/(2a)
In this case, the quadratic equation is:
y = 2x^2 - 8x + 7
Then the value h of the vertex is:
h = -(-8)/(2*2) = 2
Evaluating the quadratic equation in x = 2 we will get the value of k, so we have.
y = 2*(2)^2 - 8*2 + 7 = -1
Then the vertex is (2, -1), which means that the value of K is -1.

A seafood market sells Maryland crabs for $10.50 per Ib and Alaskan crabs for $8.50 per lb. The owner can bring 500 lbs of crabs to sell at a weekend seafood festival. How much
money can the owner earn at the festival? Show your work and explain your reasoning.
Provided the owner can bring 500 lbs of crabs to sell at the weekend seafood festival, they can earn between $4,250 and $5,250, depending on which type of crabs or their different combinations.
How are the total earnings determined?The total earnings can be determined using mathematical operations of multiplication, division, addition, and subtraction.
The total earnings are the products (multiplication results) of the units of each type of crab and their selling prices.
The selling price of Maryland crabs per Ib = $10.50
The selling price of Alaskan crabs per lb = $8.50
The total quantity of crabs the owner can bring to the seafood festival = 500 lbs
If the owner decides to bring in Maryland crabs, they can earn $5,250 ($10.50 x 500)
If the owner decides to bring in Alaskan crabs, they can earn $4,250 ($8.50 x 500)
If the owner decides to bring a combination of Maryland and Alaskan in the ratio of 50:50, they can earn $4,750 ($10.50 x 250) + $8.50 x 250)
Thus, if the owner sells Maryland crabs, the total earnings are $5,250, but if they sell Alaskan crabs, they earn $4,250.

What are Congruent triangles?Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.
Given is a geometrical diagram as shown in the image.
We can prove ΔDFC ≅ ΔAEB as follows -
AE = CF [Given]
Add length EF on both sides of the equation, we get
AE = CF ...[1]
∠ 1 = ∠ 2 [Given] ...[2]
Given is ∠ 1 = ∠ 2. Than the tangent of both angles will be same. On solving the tangent ratio, we get -

Our range is 0 x 10, We could also graph this with x along with the x-axis and w along the y-axis then every minute 50x gallons are gone
We have 500 gallons of the water tank and it drains at the rate of 50 gallons per minute,
.Let's suppose after 5 minutes,
W = 500 - 50 * 5W = 500 - 250W = 250
After 5 minutes, 250 gallons are left in the water tank.
Here the lowest value is 0 so our maximum time is once the tank emptied, or when w is equal to 0.
0 = 500 - 50x
50x = 500X = 500/50X = 10

Answer: -The probability of setting his alarm is 1-0.1=0.9
-The probability of being in time is therefore calculated as:
0.9 x 0.95 + 0.1 x 0.25
= 0.88

What is the number rounded to 3 decimal placesA decimal is a number that is made up of integers and non-integers. The integers are separated from the non-integers by a decimal point.
In order to round off a number to 3 decimal places, there must be 2 numbers to the right of the decimal point.
In order to round off a number to 3 decimal places, if the ten thousandth figure is equal to five or greater than 5, one is added to the thousandth figure. If the ten thousandth figure is less than 5, there is no change in the thousandth digit.
The ten thousandth is greater than 9, so one is added to the thousandth digit. The number becomes 387. 870

The population of a city decreases by 1.7% per year. If this year's population is 366,000, what will next year's population be, to the nearest individual?
The population of the city next year, after decreasing, will be 359,778
Here, we are given that the population of a city decreases by 1.7% per year.
This, means that the city's population will decrease by 1.7% in 1 year, (1.7 × 1.7)% in 2 years and so on.
The population of the city this year is given to be 366,000.
Thus, next year, the population will decrease by-
1.7% of 366,000
= 1.7/100 × 366,000
= 17/10 × 3,660
= 17 × 366
= 6,222
Thus, the city's total population next year will be-
366,000 - 6,222
= 3,59,778
Hence, the city's population to the nearest individual comes out to be 359,778.
