Answer:

418.6

Step-by-step explanation:

you set the price to equal 300 dollars, so marking up 40% would equal taking 300 x 1.4

this equals 420, however you need to substract 1.4 because you rounded 299 to 300 giving 418.6

Answer:

299 ×40%=119.6

so the final price is 299+119.6=418.6

Answer:

x=15

Step-by-step explanation:

Since 13+6+2x-18= 4x-29, use this equation.

Combine like terms:

1+2x= 4x-29

-1            -1

2x= 4x-30

-4x     -4x

[tex]\frac{-2x=-30}{-2}[/tex]

x=15

Answer:

A. [tex]h(x)=f(x+1)[/tex]

Step-by-step explanation:

Let's start doing exactly what each function says.

[tex]g(x) = 3x+3[/tex]

At this point, let's see what the various h-s do. Let's call each [tex]h_A... h_D[/tex] to understand which flavor of it we're talking about.

[tex]h_A(x)=f(x+1) = 3(x+1)=3x+3 = g(x)\\h_B(x)=2f(x)=2\cdot3x= 6x \ne g(x)\\h_C(x)=f(x-1)=3(x-1)=3x-3\ne g(x)\\h_D(x)= f(x)+1= 3x+1\ne g(x)[/tex]

Answer:

4e^2

Step-by-step explanation:

12 e^5

-----------

3 e^3

Divide the constants

12/3 = 4

We know that  dividing exponents with the same base means subtracting the exponents

e^5 / e^3 = e^(5-3) = e^2

4e^2

We want to see if the statement "The relationship among the triple constraint variables is such that if any one changes, at least one other is likely to be affected." is true or false. This is true.

A relationship among the triple constraint variables is written as:

y = f(x, z)

Where the 3 variables are x, y, and z and represent cost, scope, and time.

This means that if either x or z changes, also does y.

And we always can rewrite the relationship in two other forms:

x = g(z, y)

z = h(x, y)

Then we can see that always that one variable changes, at least one other variable changes in response, then the statement is true.

i hope this helped im not sure if this is right i tried to do the math but pls leave a thanks if helped

so the answer would be 8+9n≥80. The reason why is because he has $80 and he saved $8 and he earned $9 for each hour but we do not know how many hours so that is why it is n. and it says minimum so u might think that it might be ≤ but my sister says to think the opposite so the symbol will be ≥.

Hope this helps ^_^

Answer:

top one

Step-by-step explanation:

You are not including -2 (else it would be a greater or equal sign) so the dot has to be empty. You can rule out the middle options.

At this point you either remember that "greater than" means "to the right of" or you pick a convenient number, ie, 0. see that your inequality is true (zero is greater than -2) and you pick the graph where the solid line includes 0.
