The quadratic function f(x) has a vertex at (5,-5) and opens downward.

If g(x) = (x + 5)2 + 5, which statement is true?


A. The axis of symmetry of f(x) is x = 5, and the axis of symmetry of g(x) is x = -5.

B. The axis of symmetry of f(x) is x = -5, and the axis of symmetry of g(x) is x = -5.

C. The axis of symmetry of f(x) is x = 5, and the axis of symmetry of g(x) is x = 5.

D. The axis of symmetry of f(x) is x = -5, and the axis of symmetry of g(x) is x = 5.

Answers

Answer:

The correct answer is A.

Step-by-step explanation:

We're told that f(x) has its vertex at 5, -5 and opens downward.  This tells us that it's axis of symmetry is x = 5.

The format of the function g(x) shows us that its axis of symmetry is x = -5.  We're shown this because of the (x + 5)² component.

So the correct answer is A.

Using the properties of the quadratic function we can review the different answers, the correct one is

D. The axis of symmetry of f(x) is x = -5,

the axis of symmetry of g(x) is g(x) = 5.

The quadratic function is a quadratic polynomial that has a parabolic form and a general equation

        g (x) = a x² + bx + c

where a, b, c are the coefficients, x is the independent variable and g the dependent

If the function has real roots it can be written in vertex form

       g (x) = a (x-h) ² + k

where (h, k) are the coordinates of the vertex

The quadratic function has several properties:

The graph of this function opens up if the coefficient "a" is positive and down if it is negative, The axis of symmetry is parallel to the y axis, passing through the vertex of the function The vertex of the parabola corresponds to the maximum or minimum of the curve

The function can be written as a vertex value that cancels the binomial is where the symmetry axis passes

in this case, for the parabola to open downwards, the curve must be:

               g (x) = - (x + 5) ² + 5

this is the expression in vertex form, let's find the value that cancels the binomial,

              x + 5 = 0

              x = -5

at this point where the axis of symmetry passes

The value of the function for this point is

              x = -5

         g (x0 = - (-5 + 5) ² + 5

          g (x) = 5

Using the properties of the quadratic function we can review the different answers, the correct one is

D. The axis of symmetry of f(x) is x = -5, and the axis of symmetry of g(x) is

g(x) = 5

Find the length of the missing side. Simplify all radicals.

Answers

Answer:

b = 9√5 (see below)

Step-by-step explanation:

Using the Pythagorean Theorem, you can find the missing side. The two sides connect to the right angle are the legs, and the sloping side across from the right angle is the hypotenuse.

We know that:

a² + b² = c²

—where a and b are legs and c is the hypotenuse.

Plug in the known values:

a² + b² = c²

18² + b² = 27²

324 + b² = 729

b² = 405

√b² = √405

b = √81 √5

b = 9√5

Answer:

20

Step-by-step explanation:

A^2+B^2=C^2

18^2+B^2= 27^2

324+B^2= 729

-324           -324

        B^2  = 405

         B= [tex]\sqrt{405)\\[/tex]

Nick is buying one DVD player and some DVDs. At Electronics-R-Us, the DVD player is $60 and the DVDs are $12 each. At Movies-n-More, the DVD player is $80 and movies are $10 each. If the cost at the two stores is equal, how many DVDs did Nick purchase?​

Answers

if he buys 5 DVDs at electronic-r-us plus the player it would be a total of $120
60+12(5)=60
if he buys the player plus 4 movies at movies-n-more the total would also be $120
80+12(4)=60
so in total he purchased 9 DVDs

3x+4=9x-8= ????????????

Answers

3x+4=9x-8=2 the answer would be 2
Answer:

Simplifying
3x + 4 = 9x + -8

Reorder the terms:
4 + 3x = 9x + -8

Reorder the terms:
4 + 3x = -8 + 9x

Solving
4 + 3x = -8 + 9x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-9x' to each side of the equation.
4 + 3x + -9x = -8 + 9x + -9x

Combine like terms: 3x + -9x = -6x
4 + -6x = -8 + 9x + -9x

Combine like terms: 9x + -9x = 0
4 + -6x = -8 + 0
4 + -6x = -8

Add '-4' to each side of the equation.
4 + -4 + -6x = -8 + -4

Combine like terms: 4 + -4 = 0
0 + -6x = -8 + -4
-6x = -8 + -4

Combine like terms: -8 + -4 = -12
-6x = -12

Divide each side by '-6'.
x = 2

Simplifying
x = 2

The slope:

m = (14 - 10)/(3 - 1) = 4/2 = 2

The y-intercept:

10 = 2(1) + bb = 10 - 2b = 8
