Answer:

The unknown number is 2171\frac{209}{221}.

Step-by-step explanation:

Let the unknown number is x

Now we will write the equation to get the value of x.

55\frac{1}{4}% of x = 1200

\frac{221}{4}% of x = 1200

\frac{221x}{400}=1200

x=\frac{1200\times 400}{221} [By cross multiplication]

x = \frac{480000}{221}

x=2171\frac{209}{221}

Therefore, the unknown number is 2171\frac{209}{221}

Which equation reveals the minimum or the maximum value of f(x) without changing the form of the equation?
erik [133]

Answer:

A): f(x) = (x – 1)² + 2

Step-by-step explanation:

The quadratic function, f(x) = (x – 1)² + 2 is in <u>vertex form</u>: y = a(x - h)² + k, where:

  • The vertex of the graph is (h,k).
  • The value of <em>a</em> determines whether the graph opens up or down. If <em>a</em><em> </em>is <u>positive</u>, the graph opens up and the vertex is its minimum point. If <em>a </em>is <u>negative</u>, then the graph opens down, and the vertex is its maximum point.
  • The value of <em>h</em> determines how far left or right the parent function is translated.
  • The value of<em> k</em> determines how far up or down the parent function is translated.

The function, f(x) = (x – 1)² + 2, provides the pertinent information that allows us to determine the parabola's <u>minimum value</u>, as the value of <em>a</em> is a <u>positive</u>, which implies that the parabola is <em>upward facing</em>, and the vertex, (1, 2) is the minimum point.

Translate the English phrase into an algebraic expression: the quotient of A and the difference of 3 and B.
xxMikexx [17]

Hey there! I'm happy to help!

Quotient means we are dividing. We are dividing A by the difference of 3 and B. Difference means subtract, so our algebraic expression is A/(3-B).

Have a wonderful day! :D

N bisects MO. MN = 7x - 15, NO = 2x + 5. Find x
mrs_skeptik [129]

Answer:

x = 4

Step-by-step explanation:

I don't see a picture, so I'm assuming that M, N, O are points on a line segment with endpoints M and O.

Point N bisects segment MO, so it's in the middle of that segment.  That means the distance from M to N and the distance from N to O are equal.

7x - 15 = 2x + 5

5x - 15 = 5

5x = 20

x = 4
