Step-by-step explanation:

Answer:

1,200+1,200=2,400

Step-by-step explanation:

Solving the quadratic function, it is found that the range is of:

between 200 and 250; inclusive

The profit for x tours is modeled by the following equation:

[tex]p(x) = -2x^2 + 900x - 40000[/tex]

It is concave down, so the monthly profit will be of at least $60,000 between the two roots when [tex]p(x) = 60000[/tex]. Thus:

[tex]60000 = -2x^2 + 900x - 40000[/tex]

[tex]2x^2 - 900x + 10000 = 0[/tex]

Simplifying by 2:

[tex]x^2 - 450x + 50000 = 0[/tex]

Which has [tex]a = 1, b = -450, c = 50000[/tex]

Then:

[tex]\Delta = (-450)^2 - 4(1)(50000) = 2500[/tex]

[tex]x_{1} = \frac{-(-450) + \sqrt{2500}}{2} = 250[/tex]

[tex]x_{2} = \frac{-(-450) - \sqrt{2500}}{2} = 200[/tex]  

At least $60,000 includes $60,000, thus the interval is inclusive, and the correct option is:

between 200 and 250; inclusive

Question 3:

O (9 x 80) + (9 x 1) 729

Step-by-step explanation:

Distributive Property is used in algebraic expressions, to divide the equation, to make it easier to solve. For question 1,  since it was 20, you must subtract 8 from that answer, because 20 is 1 more than 19. For question 2, (2 x 9) + (2 x 3) would be the same thing as 2(9+3).

Answer:

Step-by-step explanation:

Two angles are alternate and has same measurement because line l and line m are parallel so to find x:

4x - 50 = 2x + 30

4x - 2x = 30 + 50 add/subtract like terms

2x = 80 divide both sides by 2

x = 40

Answer:

1.) Carries energy

Step-by-step explanation:

A good summary of an ATP molecule is a molecule that transfers energy between cells... meaning it carries energy from cell to cell. Furthermore, energy cannot be destroyed, and cannot be absorbed, only changed and transformed. This leaves us with two options, (1. Carries energy, and 4. None of the above). Since we already have a basic understanding of what an ATP molecule does, we can confidently determine that the correct answer is that an ATP molecule can best be described as carrying energy.

Step-by-step explanation:

Just factor, you got this!

Answer:

A system of linear equations is a collection of two or more linear equations, and a solution to a system of linear equations consists of values of each of the unknown variables in the system that satisfies all of its equations, or makes them true.

(5x² - 13x -28)/(x-4) = (x-4)(5x+7) so x = -7/5  and x = 4 are the two factors of the given polynomial.

The factors of a polynomial are those values of x for which the given polynomial satisfies.

According to the given question we have to divide a polynomial            (5x² - 13x -28) by (x - 4).

(5x² - 13x -28)/(x-4) = (x-4)(5x) + (7x - 28).

(5x² - 13x -28)/(x-4) = (x-4)(5x+7).

So, the obtained factor is (5x+7) = 0.

∴ 5x + 7 = 0

5x = -7

x = -7/5 is a factor of the given polynomial and by substituting these value in x.

(5x² - 13x -28)

5(-7/5)² - 13(-7/5) - 28 = 0

5(49/25) + 91/5 - 28 = 0

49/5 + 91/5 - 28 = 0

140/5 - 28 = 0.

28 - 28 = 0

0 = 0     ( hence satisfied that -7/5 is a factor of the given polynomial ).

#SPJ2

Answer:

.03 or 3%.

Step-by-step explanation:

Important:

I = interest

P = principal (investment)

R = simple interest rate

T = years

Formula: I = PRT

Given:

I = $240

P = 2000

T = 4 years

R = ?

Plug into formula:

240 = 2000(R)4

Multiply right side 2000*4

240 = 8000R

Divide both sides by 8000.

R = 240/8000

R = .03

The simple annual interest rate was .03 or 3%.

Therefore it .03 or 3%

Answer:

y=3

Step-by-step explanation:

Using the point slope formula

y-y1 = m(x-x1)

where m is the slope and (x1,y1) is a point on the line

y-3 = 0(x--3)

y-3 = 0(x+3)

y-3 =0

y-3+3 = 0+3
