Answer:

  m = StartFraction 9 minus 0 Over 0 minus 3 EndFraction; y = –3x + 9

Step-by-step explanation:

The given points are the y-intercept and the x-intercept, so they can be used directly in the intercept form of the equation of a line.

  x/(x-intercept) +y/(y-intercept) = 1

  x/3 +y/9 = 1

Multiplying by 9 gives ...

  3x +y = 9

This can be rearranged to the slope-intercept form ...

  y = -3x +9

_____

The answer selection shown above is the only one that matches the slope and y-intercept of the line through the given points.

Answer:

because m = StartFraction 9 minus 0 Over 0 minus 3 EndFraction; y = –3x + 9

Answer:

It took Albert 2 1/2 hours to ride to the park

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Speed of Albert to the park = 12 mph

Speed of Albert back home = 20 mph

Total time of the round trip = 4 hours

Distance each way = 30 miles

2. How long did the ride to the park take?

Let's recall that the formula of speed is:

Speed = Distance/Time, therefore Time = Distance/Speed

Time it took Albert to ride to the park = 30/12

Time it took Albert to ride to the park = 5/2 = 2 1/2 hours

Time it took Albert to ride back home = 30/20

Time it took Albert to ride back home = 3/2 = 1 1/2 hours

It took Albert 2 1/2 hours to ride to the park

Answer:

The cost for one pound of birdseed is $0.67

Step-by-step explanation:

Use Mariela's example first

To find the cost per pound, get the pounds to 1.

15 pounds = $10.00       Divide both sides by 15 to get 1 pound

1 pound = $0.67  

Use Mark's example to see if it is the same rate

12 pounds = $8.00   Divide both sides by 12 pounds to get one pound

1 pound = $0.67

Use Daryl's example to prove the other answers

18 pounds = $12.00    Divide both sides by 8 pounds to get one pound

1 pound = $0.67

Answer:

Senior citizen tickets = 9

Student tickets = 10

Step-by-step explanation:

We begin by converting the question into simultaneous linear equations;

Senior citizen tickets = a

Student tickets = b

4a + 6b = 96

8a + 13b = 202

to find a,

if 4a +6b = 96

a = 96/4 - 6b/4

a = 24 - 1.5b

We now substitute this into the second equation

8(24 - 1.5b) + 13b = 202

192 - 12b + 13b = 202

b = 202 - 192

b = 10

We now put the value of b in either equation

4a + 6b = 96

4a + 6(10) = 96

4a + 60 = 96

4a = 96 - 60

4a = 36

a = 9

The constant of proportionality for this relationship is  [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

Proportional relationship is the relation between two variables that vary directly with each other

∵ The equation is 3 y = 5 x

∵ x and y are proportional

- That means y = k x, where k is the constant of proportionality

∴ Put the equation in the form y = k x

- Divide both side by the coefficient of y

∵ The coefficient of y is 3

∴ Divide both sides of the equation by 3

∴ y = [tex]\frac{5}{3}[/tex] x

-  The value [tex]\frac{5}{3}[/tex]  is constant

∴ k =  [tex]\frac{5}{3}[/tex]

∵ k represents the constant of proportionality

∴ The constant of proportionality =  [tex]\frac{5}{3}[/tex]

The constant of proportionality for this relationship is  [tex]\frac{5}{3}[/tex]

Answer:

BC = 3.1666

Step-by-step explanation:

To solve this you need to know that cosine∅ = adjacent/hypotenuse. We already know that hypotenuse = 5 and that ∅ = 70*. By substituting these in you will get cosine 70* = adjacent/5. Evaluate cosine 70* on the calculator and get 0.633... Multiply both sides by 5 and get adjacent is about equal to 3.1666. Because BC is the adjacent side of the triangle, this is the length of BC.

It will need 864 meters³ of water to fill it completely

Step-by-step explanation:

The formula of the volume of a prism is V = B h, where

The swimming pool is shaped a prism

∵ The length of each side of the four sides is 12 meters

- That means its base is shaped a square with side length 12 meters

∵ Area of a square = (side)²

∴ The area of the base of the swimming pool = (12)² = 144 meters²

∴ B = 144

∵ The pool is 6 meters deep

- That means its height is 6 meters

∴ h = 6

The volume of the water in the swimming pool is equal to the volume of the swimming pool because it will be needed to fill completely

∴ The volume of the water = B h

∴ The volume of the water = 144(6)

∴ The volume of the water = 864 meters³

It will need 864 meters³ of water to fill it completely

Answer: 5 + 25n

Explanation: Let's simplify this problem using the distributive property.

In this problem, the 5 "distributes" through the parentheses which means that it multiplies by each of the terms inside.

So we have 5(1) + 5(5n) which simplifies to 5 + 25n.

Answer:

NO

Step-by-step explanation:

The equation y = 15/x is not a linear function. A linear process follows the form y = a + bx and graph as a straight line. The given equation doesn't track that form or behavior; hence, it is not linear.

No, the equation y = 15/x is not a linear function. In Mathematics, a linear function is defined by the equation y = a + bx, where a is the y-intercept, b is the slope, x is the independent variable, and y is the dependent variable. In this equation, the relationship between x and y is direct, meaning if x increases or decreases, y will also increase or decrease at a constant rate.

However, in the equation y = 15/x, the relationship between x and y is inverse. If x increases, y decreases, and vice versa. Furthermore, the form of the equation doesn't follow the standard form of a linear equation (y = a + bx) because the x variable is in the denominator. Therefore, it is not linear because it will not graph as a straight line.

Answer:

i) $500 at 5% simple interest for two years.

   Interest = 550 - 500 = $50

ii) $500 at 3% compounded monthly for 2 years.

   Interest = 530.88 - 500 = $30.88

I would take the first option i)$500 at 5% simple interest for two years.

Step-by-step explanation:

i) $500 at 5% simple interest for two years.

  Initial amount, P = $ 500

  Rate of interest, r = 0.05

  Time in years, t = 2

 Therefore Final amount A = P(1 + rt) = 500(1 + (0.05  2) ) = $550

  Therefore Interest = 550 - 500 = $50

ii) $500 at 3% compounded monthly for 2 years

   Initial or Principal Amount, P  = $500

   Rate of interest, r =0.03

   number of conversions, m = 12

    Time in years, t = 3

 Therefore final amount,   = $530.88

Therefore Interest = 530.88 - 500 = $30.88

I would take the first option i) $500 at 5% simple interest for two years.

so

by proportion

Find out the distance traveled by the vehicle in 23,000 revolutions

Simplified expression for total amount spent is 10(2.05 + m)

Step-by-step explanation:

Expense = 8.50 + 6.25 × m

Expense = 12 + 3.75 × m

Total Amount = 8.50 + 6.25m + 12 + 3.75m = 20.5 + 10m = 10(2.05 + m)

Sabra spends a total amount represented by the simplified expression 20.50 + 10m after m months on both the cooking and movie clubs.

To find the total amount of money Sabra spends on both clubs after m months, we need to consider the costs of joining each club and the ongoing monthly fees.

Sabra's cooking club costs $8.50 to join and $6.25 per month. This can be represented by the expression:

Sabra's movie club costs $12 to join and $3.75 per month. This can be represented by the expression:

To find the total amount spent on both clubs, we sum these expressions:

So, the total amount of money Sabra spends on both clubs after m months can be expressed as 20.50 + 10m

Answer:

46

Step-by-step explanation:

47.84 / 1.04, which is 46

The opening price of Company A's stock before the 4% increase to the closing price of $47.84 was $46.00.

To calculate the opening price of Company A's stock at the beginning of the day, before the 4% gain, we need to work backwards from the closing price. Since the stock closed at $47.84 after gaining 4%, we can represent the closing price as 104% of the opening price. Thus, the equation to find the opening price (OP) is:

OP x1.04 = $47.84

Now we solve for OP:

OP = $47.84 / 1.04

OP = $46.00

The opening price of Company A's stock at the beginning of the day was $46.00.

45 metres

Step-by-step explanation:

You have to get the base to answer the question.

Do this by dividing 315 by 15 then timesing by 2

You get 42.

Do 42^2 = 1764

Do 15 ^2 = 225

Because you want the hypotenuse you add them

1764 + 225 =1989

Do the square root of 1989 which is 45 to the nearest metre

Answer:

25.80

Step-by-step explanation:

Area = 315 [tex]m^{2}[/tex]

Area = l*b

315 = 15 *b

b= 315/15

b = 21

From Right angled Triangle ,

Hypotenuse square = side square + side square

[tex]x^{2}[/tex] = [tex]21^{2}[/tex] + [tex]15^{2}[/tex]

[tex]x^{2}[/tex] = 441 + 225

[tex]x^{2}[/tex] = 666

apply sq root on both sides, the we get

[tex]\sqrt{x^{2}} = \sqrt{666}[/tex]
