Answer:

  B, E

Step-by-step explanation:

You are give a table of values of x and f(x). You are told that g(x) = (1/2)f(x), and you are asked for points (x, g(x)) that match that description.

It can be useful to mentally, or actually, add a third column to the table that shows the values of g(x). Each of those is half the corresponding value of f(x), because that is what g(x) = (1/2)f(x) means.

Having done that, you can then compare the ordered pairs (x, g(x)) to those in the answer list to see which ones match. The ones that match are highlighted in green in the attachment:

Answer:

  a) y = (x -4)² -4

  b) (4, -4)

  c) translated 4 right, 4 down

Step-by-step explanation:

a) Apparently "graphing form" is a reference to "vertex form." That form is ...

  y = a(x -h)² +k . . . . . . parabola with vertex (h, k) and vertical scale factor 'a'

The coefficient of x² in your given equation is 1, so a=1. The values of h and k can be found as follows.

'h' is the opposite of half the x-coefficient in your equation, so is h = -(-8/2) = 4. The value of k is the square of h, subtracted from the constant in your equation: k = 12 -h² = 12 -16 = -4. (This applies when a=1, as here.) These calculations are the "cut to the chase" version of "completing the square."

The method of "completing the square" has you consider the x-terms separately from the constant term:

  y = (x² -8x) +12

To "complete the square", you want to make the terms in parentheses be a perfect square trinomial. You do that by adding the square of half the x-coefficient. In order to keep the same equation, you need to subtract an equivalent amount outside parentheses:

  y = (x² -8x +(-8/2)²) +12 -(-8/2)² . . . . . add and subtract (-8/2)²

  y = (x -4)² +(12 -16)

Then the vertex form is ...

 y = (x -4)² -4 . . . . and the vertex is (h, k) = (4, -4).

The graphing calculator plot attached confirms this vertex value.

__

The problem statement tells you that you can also find this form by averaging the x-intercepts. If you factor your equation, you get ...

  y = (x -6)(x -2)

The x-values that make these factors zero {6, 2} are the x-intercepts. Their average (6+2)/2 = 4 is the x-coordinate of the vertex (h). You can find the y-coordinate of the vertex by evaluating y when x=4: y = 4² -8·4 +12 = -4. So, the vertex by this method is (h, k) = (4, -4), and the equation in graphing form is ...

  y = (x -4)² -4 . . . . as above.

__

b) As we saw above, the vertex coordinates are (h, k) = (4, -4).

__

c) The vertical scale factor 'a' is 1, so the only transformation done on the graph is to move the parent vertex (0, 0) to the location (4, -4). That is, the graph has been translated 4 units right and 4 units down. (In the attached, the parent function is shown with a dashed line.)

Step-by-step explanation:

Since the sum of the digits must be an integer, the number itself must also be a multiple of 5.

Lowest common multiple of 5 and 9 = 45.

Therefore the number could be 45 or 90.

5(9 + 0) =/= 90, so 90 is incorrect.

Since 5(4 + 5) = 45, 45 is the answer.

Answer: 45

Step-by-step explanation:

We know that it has to be a 2-digit number. Its the multiple of 9. We see there is a number in the question. Five. I simply took 9 and multiplied it by 5 which gave me a total of 45.

Answer:

[tex]2\sqrt{10}[/tex]

Step-by-step explanation:

Take [tex]a^{2} +b^{2} +c^{2}[/tex], let x represent a, 9 represent b, and 11 represent c.

Now, plug your variables into the equation:

[tex]x^{2} +9^{2} =11^{2}[/tex]

Simplify:

[tex]x^{2} +81=121[/tex]

Subtract:

[tex]x^{2} =40[/tex]

Take the square root of 40:

Answer:

The answer is

[tex]y = 2x + 13[/tex]

Step-by-step explanation:

Remember:

[tex]Slope-intercept form: \: \\ y = mx + b \\ \\ m = slope \\ b = y - intercept[/tex]

[tex]M = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

First: Find the slope.

[tex]M = \frac{13 - 5}{0 - ( - 4)} = \frac{8}{4} = 2[/tex]

.

Second: Solve for the y-intercept

[tex]y = mx + b \\ 5 = 2( - 4) + b \\ 5 = - 8 + b \\ \frac{+ 8 = + 8 \: \: \: \: \: \: \: \: }{13 = b} [/tex]

.

Third: Plug in.

[tex]y = mx + b \\ y = 2x + 13[/tex]

Answer:

Step-by-step explanation:

this is okay  ... use the point-slope formula [y-y1=m(x-x1)] with your given point.. also m is the slope.. which as is.. is undefined.. so just leave it like that.. the teacher is making this too abstract thou.. to make sense

y-2=m(x-(-3))

y-2 = m(x+3)

y-2 = mx +3m

y = mx +3m +2

that's all you could do for now.. until the slope is defined  :)

Answer:

y-2=m(x-(-3))

y-2 = m(x+3)

y-2 = mx +3m

y = mx +3m +2

Answer:

52% of the grid is shaded. You would need 7 more squares in order to get 80%.

Step-by-step explanation:

There are 25 boxes. You want to figure out how much each box is worth.

So,

You divide 100 by 25. You will get an answer of 4.

So now you know how much each box is worth.

There are 13 boxes shaded in, so you multiply 13 by 4 to get 52.

Keep adding boxes in order to get 80%. For example, 52%, 56%, 60%, until you get to 80%. Then see how many boxes you added up to get 80%.

We would need 7 more squares in order to get 80%. Thus, 52% of the grid is shaded.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

There are 25 boxes. we want to figure out how much each box is worth.

So,

100 / 25 = 4

Now, we know how much each box is worth.

There are 13 boxes shaded in,

so 13 x 4 = 52.

Keep adding boxes in order to get 80%.

For example, 52%, 56%, 60%.

Answer:

Number of tickets sold in advance = 310

Number of tickets sold  at the door = 340

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

For the school play, the advance tickets cost $3, while tickets at the door cost $5. Thirty more tickets were sold at the door than in advance, and $2630 was collected. How many of each kind of ticket were sold?

The explation of the answer is now given as follows:

Let a represents number of tickets sold in advance. Therefore, we have:

a = number of tickets sold in advance at $3 each

a + 30 = number of tickets sold  at the door at $5 each

The total amount collected can be represented by this equation:

3a + 5(a + 30) = 2630

Solving for a, wee have:

3a + 5a + 150 = 2630

8a = 2630 - 150

8a = 2,480

a = 2,480 / 8

a = 310

Therefore, this implies:

Number of tickets sold in advance = 310

Number of tickets sold  at the door = a + 30 = 310 + 30 = 340
