Answer:

the awnser is c

Step-by-step explanation:

A- 100:1 would mean it is a 10000% markup

B- 1:100 lower than b so eliminate

C- 2:1 So a is double the amount of b so it's 100%

D- 1:2 B is 100% of a so it's flipped, not what question is asking for

So process of elimination shows that C is the correct awnser

Answer:

The values of a,b,c and d are as follows:

a = 3, b = -12, c = -5, d = 10

Step-by-step explanation:

Given functions are:

[tex]f(x) = 4x^3-12x^2+10\\g(x) = x^3-2x^2+5x[/tex]

We have to find the value of f(x) - g(x). This means we have to subtract function g(x) from function f(x)

So,

[tex]f(x) - g(x) = (4x^3-12x^2+10)-(x^3-2x^2+5x)\\= 4x^3-12x^2+10-x^3+2x^2-5x[/tex]

Combining alike terms

[tex]= 4x^3-x^3-12x^2+2x^2-5x+10\\= 3x^3-10x^2-5x+10[/tex]

Now it was given that:

f(x)- g(x)= ax^3+bx^2+ cx+d

By comparing both we get

a = 3, b = -12, c = -5, d = 10

Hence,

The values of a,b,c and d are as follows:

a = 3, b = -12, c = -5, d = 10

Answer: C. 3(b-2)=24

Step-by-step explanation: See since b equals ten and by the rules of P.E.M.D.A.S the parenthesis/brackets comes first so 10-2 equals 8 and three times 8 is 24 therefore the answer is 24

Answer:

The slope is 0 because it is a straight line

Step-by-step explanation:

Answer:

undefined.

Step-by-step explanation:

You could be really formal and use the slope formula

The y values are both the same -- 4.

The x values are 3.5 and 6.5

Therefore  the slope is (6.5 - 3.5) / (4  -  4)

The denominator is 0

The slope is undefined because 3/0 is not very well behaved.

A horizontal line always gives an undefined amount.

Answer:

y=mx+b

Step-by-step explanation:

Answer:

y = (5/2)x - 5

Step-by-step explanation:

SLOPE:

The slope is rise over run, and in this case (thanks to the graph), we can do the [difference of y] / [difference of x] pretty easily. This is 5 / 2

Y-INTERCEPT:

Y-intercept is simple: where the line touches the y-axis. This happens at y = -5.

Therefore, the equation y = (5/2)x - 5

Answer:

-47

Answer:

So all the possible solutions are:

Solution Steps:

First you need to solve the real inequality to understand how to find the rest of the possible equations.

Subtract 13.2 from both sides:

So now we know the real answer, but now we must find all the possible solutions.

(Means anything greater than or equal to 217.6 when you plug it into x + 13.2 ≥ 217.6.)

Numbers that are greater than 378:

  1.)  [tex]204.4+13.2=217.6[/tex] ≥ [tex]217.6[/tex]  (True)

  2.)  [tex]217.6+13.2=230.8[/tex] ≥ [tex]217.6[/tex]  (True)

  3.)  [tex]204.3+13.2=217.5[/tex] ≥ [tex]217.6[/tex]  (False)

  4.)  [tex]0+13.2=13.2[/tex] ≥ [tex]217.6[/tex]  (False)

  5.)  [tex]13.2+13.2=26.4[/tex] ≥ [tex]217.6[/tex]  (False)

  6.)  [tex]200.4+13.2=213.6[/tex] ≥ [tex]217.6[/tex]  (False)

  7.)  [tex]-200+13.2=-186.8[/tex] ≥ [tex]217.6[/tex]  (False)

  8.)  [tex]13.2+13.2=26.4[/tex] ≥ [tex]217.6[/tex] (False)

Now put all the numbers together to form the code.

(Could either be the numbers on the side of the table or the accumulation of all the numbers in possible solutions.)

Scientific notation is simply changing a number to x times 10^n, where x is no more than 10 and more than 1.

For example, 134 would be 1.34 times 10^2.

x = -3/4

Step-by-step explanation:

Because you have the variable x and you do not know the number of fruit snacks he ate and you need to have the same variables to properly find the answer.

Answer: option B

Step-by-step explanation:

-4, 1, 3

The roots of the polynomial equation x³ - 7x = 6x - 12 is given by the values x = -4 , 1 , 3

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the polynomial equation be represented as A

Now , the value of A is

x³ - 7x = 6x - 12   be equation (1)

Now , it can be represented as 2 equations of the form

A = x³ - 7x   be equation (2)

And , B = 6x - 12    be equation (3)

On plotting the graphs of the two equations , we get

The point of intersection of the equations is at P ( -4 , -36 ) , Q ( 1 , -6 ) and R ( 3 , 6 )

Therefore , the x coordinates of the points are x = -4 , 1 , 3

Hence , the roots of the polynomial is x = -4 , 1 , 3
