Which of the following are written in point-slope
form?
a) y = 4x + 6
b) y + 3 = -2(x – 6)
c) x + y = 10
d)y- 1 = 5(x + 7)

Answer: y = 800

Step-by-step explanation:

3(y + 200) = 3000

3y + 3(200) = 3000

   3y + 600 = 3000

              3y  = 2400     [Subtract 600 from both side]

                y   = 800      [Divide 3 in both side to solve for y]  

Answer:

18

Step-by-step explanation:

Given the data:

180kg, 250kg, 200kg, 209kg, 195kg, 205kg, 190kg, 188kg, 192kg

The interquartile range (IQR) = Q3 - Q1

Reordering the data:

180, 188, 190, 192, 195, 200, 205, 209, 250

Q3 = 3/4(n+1)th term

Q3 = 3/4(10) = 7.5 th term = (205+209)/2 = 207

Q1 = 1/4(n+1)th term

Q1 = 1/4(10) = 2.5th term = (188+190)/2 = 189

Q3 - Q1 = 207 - 189 = 18

Answer:

The answer is D

Step-by-step explanation:

We want to see which of the given values is a solution of the inequality:

x < 4

The correct option is A, x = 3.

So the inequality:

x < 4

This means that the variable must be a number smaller than 4.

Then we just need to select the option that is smaller than 4, the only option that meets this requirement is option A, x = 3

Also, as you can see in the number line, the only number that is in the shaded part is x = 3 (from the ones in the options).

Answer:

2.5 years

Step-by-step explanation:

Given data

Principal= Rs 24000

Final amount A= Rs 30000

Rate r= 10%

The simple interest expression is

A=P(1+rt)

substitute

30000=24000(1+0.1*r)

30000=24000+2400t

30000-24000=2400t

6000=2400t

t= 6000/2400

t=2.5

Hence the time is 2.5 years

Answer:

A

Step-by-step explanation:

given the sequence above using using two as a first term the only formula fits the sequence above is A

Answer:

A

Step-by-step explanation:

There is a common ratio r between consecutive terms

r = 8 ÷ 2 = 32 ÷ 8 = 128 ÷ 32 = 4

This indicates the sequence is geometric with nth term ( explicit formula )

[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 2 and r = 4 , then

[tex]a_{n}[/tex] = 2 . [tex]4^{n-1}[/tex] → A

Answer:

m∠2 = 104°

m∠3 = 76°

m∠4 =  104°

Step-by-step explanation:

∠1 and ∠3 are vertical angles

That means they are of the same value.

∠2 and∠4 are also vertical angles and we can find the value like this:

Sum of all angles = 360°

Total value of found angles = 152°

Number of angles need to be found = 2x (note: this is 2x because both angles are the same)

Equation = 360 - 152 = 2x

208 = 2x

x = 208/2

x = 104

So angle m∠4 = 104°

and m∠2 = 104°

Answer:

The pool that they buy is the circular pool which Marsha wants

The cost of the circular pool is $471.25

Step-by-step explanation:

The parameters of the swimming pools which each of Pete and Marsha wants to buy is given as follows;

The dimensions of the pool Pete wants = 18 feet wide, 20 feet long and 6 feet deep

The dimensions of the circle shaped pool Marsha wants = 20 feet across and 6 feet deep

The price of water, P = 25 cents per cubic foot

The pool they decide to buy = The pool that costs less to fill

The volume of water to fill the pool Pete wants, V₁ = 18 ft. × 20 ft. × 6 ft. = 2,160 ft.³

The cost of filling the pool Pete wants, C₁ = V₁ × P

∴ C₁ = 2,160 ft.³ × 25cents/ft.³ = 54,000 cents = 540 Dollars

The volume of water to fill the pool Marsha wants, V₂ = π·(20 ft.)²/4 × 6 ft. ≈ 1,884.96 ft.³

The cost of filling the pool Marsha wants, C₁ = V₁ × P

∴ C₁ ≈ 1,884.96 ft.³ × 25 cents/ft.³ ≈ 47,124 cents = 471.24 Dollars

The pool that they buy is the circular pool that Marsha wants and it costs $471.24 to fill
