Answer:

Theory

Step-by-step explanation:

The term theory is associated to a "set of logical interrelated concepts, statements, propositions, and definitions", who are "derived from philosophical and logical beliefs from scientific data and from which questions and hypotheses can be deduced, characterize, tested and verified".

So then we can conclude that :

A set of logically interrelated concepts, statements, propositions, and definitions supported by data, testing, and verification to account for or characterize some phenomena is called theory.

200 + 10x = 120 + 15x now solve the equation to find x, the number of hours that both companies will charge the same ammount
torisob [31]

Answer:

16

Step-by-step explanation:

Given the equation, 200 + 10x = 120 + 15x, let's solve for x as follows,

Subtract 200 from both sides

200 + 10x - 200 = 120 + 15x - 200

10x = - 80 + 15x

Subtract 15x from both sides

10x - 15x = - 80 + 15x - 15x

-5x = - 80

Divide both sides by -5

\frac{-5x}{-5} = \frac{-80}{5}

x = 16

What are the real zeros of f(x) = x^3 +2x^2-5x-6
netineya [11]

First of all Horner
First we try with -3
1. 2. -5. -6.
-3. 3. 6
1. -1. -2. 0
To verify: -3^3+2*-3^2+15-6=0

Now we have this equation
(X+3)*(x^2 - x -2)=0

I dont know If you know sum and product but that is the easiest way so sum= 1 product = 2 so 2 and -1 are the answers.
You can do this too by this way : b^2-4ac= D
X= (-b(+or-)d^1/2)/2a

So all the zeros
2, -1 and -3

the point slope form of the equation of a line that passes through (8,4) and (0,2) is y-4=1/4(×-8) what is the slope intercept f
marissa [1.9K]

Answer:

\large\boxed{y=\dfrac{1}{4}x+2}

Step-by-step explanation:

The slope-intercept form of the equation of a line:

y=mx+b

m - slope

b - y-intercept → (0, b)

The point-slope form of the equation of a line:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

We have the equation of a line:

y-4=\dfrac{1}{4}(x-8)\to m=\dfrac{1}{4}

and the point (0, 2) → b = 2.

Substitute:

y=\dfrac{1}{4}x+2
