On what interval is the function positive?

Answers

Answer 1

Answer: (-∞,2)

Step-by-step explanation: 2 is not included in the interval since at x=2, the function crosses the x axis, meaning it is not positive, and instead 0.

All x values below 2 are positive.

y is directly proportional to x 2 . If y = 8 when x = 2 find y when x = 3

Someone help will give you 5star and brainliest

Answers

Answer:

We know that if

y ∝ x²

∴ y = k · x²

Now

y = 8 , x = 4

From above y = k · x²

⇒ 8 = k · 4²

∴ k = 1/2

Again ....

x = 5 , y = ?

y = k·x²

y = 1/2 × 5²

= 25/2 = 12.5

Ben is n years old.
Chloe is twice as old as Ben.
Dan is five years younger than Ben.
The total of Ben’s age, Chloe’s age and Dan’s age is T years.
(a) Find a formula for T in terms of n.

Answers

Answer:

T = 4x - 5

Step-by-step explanation:

Let x = Ben's age

2x = Chloe's age

x - 5 = Dan's age

Combine all the terms and simplify to form an equation.

T = 2x + x + x -5

T = 4x - 5

nth term of -7 -12 -17 -22 -27

Answers

Answer:

[tex]a_n=-2-5n[/tex]

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

The equation to calculate the nth term of an arithmetic sequence is:

[tex]a_n=a_1+(n-1)r[/tex]

Where

an = nth term

a1 = first term

r = common difference

n = number of the term

We are given the sequence

-7 -12 -17 -22 -27 ...

The first term of this sequence is a1=-7. We can calculate the common difference by subtracting two consecutive terms:

r = -12 - (-7) = -12 + 7 = -5

The nth term is:

[tex]a_n=-7+(n-1)(-5)[/tex]

Multiplying:

[tex]a_n=-7-5n+5[/tex]

Simplifying:

[tex]\boxed{a_n=-2-5n}[/tex]

3(x - 4) = 3x - 12 (expand the brackets)
3x - 12 = 2x + 6
3x = 2x + 6 + 12 (put all of the integers on one side)
3x = 2x + 18 (simplify - collect like terms)
3x - 2x = 18 (put all of the unknowns on one side)
x = 18 (simplify - collect like terms)

Therefore, we know that x is equal to 18, and so the answer is E.

3 consecutive integers is 234. What is the equation to solve this equations and what are the 3 integers?

Answers

Answer:

1. The equation to solve this equations is:

= 3x = 231

2. The three integers are 77, 78 and 79.

Step-by-step explanation:

The sum of 3 consecutive integers = 234

let x = first integer

let x+1 = second integer

let x+2 = third integer

Therefore,

= x + x + 1 + x + 2 = 234

simplified to:

= 3x = 231

b) Adding three consecutive numbers adds the smaller number to itself three times, and then adding 1 for the second number, and two for the third number. So, the sum of the three consecutive numbers is divisible by 3. Therefore, to get the second (or middle) number, divide the total by 3, and then subtract 1 and add 2 to get the first and the third numbers, respectively.

Lori needs more than 250 signatures to run for the position of class president for her middle school. She already has 75 signatures and believes that she can get 25 more signatures each day. She wants to figure out how many days, d, she should collect the signatures she needs. Which inequality and solution for d correctly represent Lori’s situation?

Answers

Answer:

75 + 25d > 250

d > 7

Step-by-step explanation:

Number of signatures needed : > 250

Amount of signatures ready = 75

Exoected number of signatures per day = 25

Number of days, d, needed signatures will be collected ;

Number of ready signatures + (expected number of signatures per day * number of days) > number of signatures needed

Mathematically,

75 + 25d > 250

25d > 250 - 75

25d > 175

d > 175 / 25

d > 7

3. Me blank el pan.O encantaO encantan Blue Ridge Hot Tubs manufactures and sells two models of hot tubs: the Aqua-Spa and the HydroLux. Howie Jones, the owner and manager of the company, needs to decide how many of each type of hot tub to produce during his next production cycle. Howie buys prefabricated fiberglass hot tub shells from a local supplier and adds the pump and tubing to the shells to create his hot tubs. (This supplier can deliver as many hot tub shells as Howie needs.) Howie installs the same type of pump for both hot tubs. He will have only 200 pumps available during his next production cycle. From a manufacturing standpoint, the main difference between the two models of hot tubs is the amount of tubing and labor required. Each Aqua-Spa requires 9 hours of labor and 12 feet of tubing. Each Hydro-Lux requires 6 hours of labor and 16 feet of tubing. Howie expects to have 1,566 production labor hours and 2,880 feet of tubing available during the next production cycle. Howie earns a profit of $350 on each Aqua-Spa he sells and $300 on each Hydro-Lux he sells. He is confident that he can sell all the hot tubs he produces.
