My little sister needs help with this question. . .

Choose the equation that is based on the description “nine more than twelve times a number equals one.”

\bold{A.~9x~+~12~=1}

\bold{B.~9x~+~1~=12}

\bold{C.~12x~+~1~=9}

\bold{D.~12x~+9~=1}

But- I think for the answer for her will be is :

B. Just saying in my opinion.

Please make an explanation to this. . .

Or, maybe you can show proof how you got the answer ?

Answer:

Answer- D

Step-by-step explanation:

It says' nine more than' so that means a +9 is there. It says '12 times' so multiply by 12.

Taking x.

12 multiplied by x and then if we add 9 our answer is 1

so 12x+9=1

Whenever there is equal to something it means it's =something. As u said it might be B, B is wrong cuz it says equal to one and not equal to 12.

Hope it helps!

Mr. Castillo earns 270,920.64 a year. What is his monthly salary?
lozanna [386]

We need to divide for this. Since there are 12 months in a year, we divide his yearly salary by 12.

270,920.64÷12=22,576.72


So, Mr.Castillo's monthly salary is $22,576.72.

What is the slope of the line that passes through the points (-4, -9) and (5, 3)
egoroff_w [7]

Answer:

4/3

Step-by-step explanation:

Moving from (-4, -9) to (5, 3), x (the 'run') increases by 9 from -4 to 5, and y (the 'rise') increases by 12 from -9 to +3.  Thus, the slope of the line connecting the two points is

m = rise / run = 12/9 = 4/3

It may help to think of the change in x (9) as the horizontal leg of a right triangle and the change in y (12) as the vertical leg.  Then  

m = (vertical leg length) / (horizontal leg length) = 12/9 = 4/3

Task 3:
Natalija [7]

Answer:

A.   4.5 ft

B.    4 ft

C.    1 ft

Step-by-step explanation:

If you pretend that h is replacing y and d is replacing x and you would graph the equation, then you would get a parabola that opens down.

You would need to find the vertex of the parabola.  The ordered pairs would be (d, h) instead  of the normal (x, y).  

A.  The maximum height will be the h value of the vertex

B.   Let h = 0 and solve the equation for d.  That will give you distance from the stump that the frog landed.

C.  The distance from the log at the maximum height is the d value of the vertex

So, that is what is needed to be done.

Without me going thru all the work, the vertex is (1, 4.5) and the solutions to the equation when h = 0 are 4, -2  (discard -2 since a distance cannot be negative)

So the answer to A is 4.5 ft.

The answer to B is 4ft.

The answer to C is 1 ft.

Now, can you find the vertex on your own and can you solve the equation when h = 0?  I hope so.  OK?
