What is the equation of the axis of symmetry?

Answer:

D. none

Step-by-step explanation:

to figure out if the point is on the graph, take the x value and plug it in to the x coordinate, do the same for y. if the values truly add up to 2, then it is on the graph. Since none of the values add up to 2, they are not on the graph.

Answer:

Step-by-step explanation:

Given:

Find the composite function (g·h)(t):

Find (g·h)(-4 + t):

The given information is,

→ g(t) = t + 5

→ h(t) = 3t - 2

Now we have to,

find the composite function (g•h)(t),

→ (g•h)(t)

→ g(h(t))

→ (3t - 2) + 5

→ 3t + 3

Let's find the (g•h)(-4 + t):

→ (g•h)(-4 + t)

→ g(h(-4 + t))

→ 3(-4 + t) + 3

→ -12 + 3t + 3

→ 3t - 9

Hence, the value is 3t - 9.

Answer:

-72

Step-by-step explanation:

Substitute -4 in the equation

h(-4) = -20 + 13(-4)

h(-4) = -20 + -52

h(-4) = -72

-72 is the final answer

Answer:

Step-by-step explanation:

You are giving away a lot of points. Usually 20 will attract our attention. I mean you put up 20 and we get 10. It's enough.

h(t) = - 20 + 13t

In this case t is going to be - 4

h(-4) = -20 + 13(-4)

h(-4) = -20 - 52

h(=4) = -72

Reduce fractions to their lowest terms equivalents

Multiply the numerators and denominators of the fractions separately

[tex]\frac{7}{15}[/tex] * 120 = convert to fraction

[tex]\frac{7}{15}[/tex] * [tex]\frac{120}{1}[/tex] = convert to fraction

[tex]\frac{7 * 120}{15}[/tex] = apply fraction rule  [tex]\frac{a}{b}[/tex] * [tex]\frac{c}{d}[/tex] = [tex]\frac{a * c}{b * d}[/tex]

[tex]\frac{7 * 120}{15 *1}[/tex] = apply rule a * 1 = a  15 * 1 = 15

[tex]\frac{120}{15}[/tex] = 8 divide the numbers

7 * 8 = 56 multiply the numbers

Answer:

Step-by-step explanation:

Write 34 in tens and units.

 A store advertises,

"Buy one and get one half off"

Which means if we buy one, half the price of one will be discounted.

In other words "50% discount on each item we buy"

We will $440 for 10 skates.

Original cost of skates = $88

After 50% discount price of one skate = $88 - $44 = $44

Cost of 10 pairs of skates = 44 × 10

                                           = $440

     Therefore, we will pay $440 for 10 skates.

All the elements of the given set {2,4,8,...,256} are - {2, 4, 8, 16, 32,64, 128, 256} that are total 8 in numbers.

The set is formed by the number of objects in a particular manner, these objects are called elements of the set. The elements of the set are written inside a curly bracket separated by a comma in a particular or specific order.

There are two methods to represent the set and its elements that are:

in this case, {[tex]2^{1},2^{2},2^{3},2^{4},2^{5},2^{6},2^{7},2^8[/tex]} as we know,

     We can solve this problem by using the fact that speed of typing is defined as the words typed in unit time.

Dana will type [tex]2.6\times 10^5[/tex] words in 48.15 hours.

It's given in the question,

Since, 1 minute = [tex]\frac{1}{60}[/tex] hours

Therefore, number of words she can type = [tex]\frac{90}{\frac{1}{60}}[/tex]

                                                                      = 90×60

                                                                      = 5400 words per hour

Number of words Dana types with the given speed in 'x' hours = Speed of typing × Time

= [tex]5400\times x[/tex]

Therefore, [tex]5400\times x =2.6\times 10^5[/tex]

[tex]5400x=260000[/tex]

[tex]x=\frac{260000}{5400}[/tex]

[tex]x=48.15[/tex] hours

Answer:

Step-by-step explanation:

Original equation

    √x+6-4 = x

   Isolate

    √x+6 = 4+x

Raise both sides to the second power

    (√x+6)2 = (4+x)2

    After squaring

    x+6 = x2+8x+16

Rearranged equation

    x2  + 7x  + 10 = 0

    This equation has two rational roots:

      {x1, x2}={-2, -5}

Original equation, root isolated

Step-by-step explanation:

apply the BODMAS method

Here, we need to find the monthly and the weekly growth rate

The monthly growth rate is 99.33 ounces and the weekly growth rate is 22.9 ounces

Weight at birth = 8 ounces

Weight at one year =75 ounces

1 pound = 16 ounces

75 pounds = 1200 ounces

Additional weight after birth = Weight at one year - Weight at birth

= 1200 ounces - 8 ounces

= 1,192 ounces

There are 12 months in a year

Growth rate per month = Additional weight after birth / 12

= 1,192 / 12

= 99.33 ounces per month

There are 52 weeks in a year

Growth rate per week = Additional weight after birth / 52

= 1,192 / 52

= 22.9 ounces per week

Answer:

  a) J(K(x)) = x; K(J(x)) = x; functions are inverses

  b) f(g(x)) = 8 -x; g(f(x)) = -x; functions are not inverses

  c) f(x) = 4 -x; f^-1(x) = 4 -x. g(x) = x -4; g^-1(x) = x +4

Step-by-step explanation:

a) Substitute for the function argument in the usual way. If the functions are inverses, their composite is the identity function.

  J(K(x)) = J(1/3x -2) = 3(1/3x -2) +6 = x -6 +6 = x . . . . functions are inverses

  K(J(x)) = K(3x +6) = 1/3(3x +6) -2 = x +2 -2 = x . . . . functions are inverses

__

b) f(g(x)) = f(x -4) = 4 -(x -4) = 4 -x +4 = 8 -x . . . . functions are not inverses

  g(f(x)) = g(4 -x) = (4 -x) -4 = -x . . . . functions are not inverses

__

c) To find the inverse function for y = f(x), solve x = f(y).

The inverse of f(x) = 4 -x is ...

  x = f(y) = 4 -y

  y = 4 -x . . . . . add y-x to both sides

  f^-1(x) = 4 -x

and for g(x) = x -4, the inverse is ...

  x = g(y) = y -4

  x +4 = y

  g^-1(x) = x +4
