2/x + 9 is the answer

Answer:

9 + \frac{2}{x}

Step-by-step explanation:

I guess this exercise is about translating the problem directions to math language...

The first part states "nine more than...". Usually, "more than" can be translated to addition, in this case the addition of 9 and an expression that needs to be determinated. This can be translated to math language as:

9 + ...         (1)

The second part of the statement says "the quotient of two and a number x". Quotient means division, in this case the division of 2 and x. Then we have:

... + \frac{2}{x}          (2)

Putting (1) and (2) together, the answer is

9 + \frac{2}{x}

Which equation represents a parabola that opens upward has a minimum at x=3 and has a line of symmetry at x=3
umka2103 [35]

Answer:

y=x^2-6x+5

Step-by-step explanation:

Let us consider the equation y=x^2-6x+5

For a quadratic equation in a standard form, y=ax^2+bx+c, the axis of symmetry is the vertical line x = \frac{-b}{2a}.

Here in this case we have, a=1, b=-6 , c =5

Putting the values we get,

x = \frac{-(-6)}{2\times 1} = \frac{6}{2} =3

We can see that the axis of symmetry is x=3 and the graph is giving minimum at x=3.

Therefore, the required equation is y=x^2-6x+5. Refer the image attached.

Choose as many answers as apply.
alexandr1967 [171]

Answer:

  • multiplying a multi-digit number by itself several times (finding the power of a number)
  • finding a square root
  • statistical calculations

Step-by-step explanation:

We don't know what your introduction tells you, but the above-listed operations are ones I choose to use a calculator for. I also use a calculator for ordinary arithmetic, such as division by numbers with 2 digits or more. (It is simply faster and requires no scratch paper.)

If statistical calculations are not done with a calculator, they at least require the availability of suitable tables.

___

All of these operations can be done by hand without a calculator, and were in times passed. Lifetimes of effort were involved in generating some of the original math tables for statistics, trig, logarithms, and other functions readily evaluated using a modern calculator.

If you vertically compress the linear parent function, F(x) = x, by multiplying by 1/2 , what is the equation of the new functio
ElenaW [278]
Vertical compression of a function is moving the graph of the function towards the x axis.
It is done by multiplying F(x) with IaI<1, the absolute value of a is less than 1. Then we get f(x)=a*F(x).

If we have a function F(x)=x, and we multiply it by a=1/2, we get:

f(x)=a*F(x)=a*x=(1/2)*x.

This linear function is vertically compressed because the the graph of a new function is closer to the x axis.
