Answer:

f(8) = -9

Step-by-step explanation:

Substitute 8 in for x.

f(8) = -2(8) + 7

f(8) = -16 + 7

f(8) = -9

The options that shows the Commutative Property of Multiplication is:

A) 4x5=5x4

C) (3 x 2) × 7 = 3 ×(2 x 7)

Answer:

  215.6 cm^2

Step-by-step explanation:

The top and bottom "wings" are 3.25 cm by 12.25 cm, so each has an area of ...

  A = LW

  A = (12.25 cm)(3.25 cm) = 39.8125 cm^2

The left and right "wings" are 3.25 cm by 7.25 cm, so each has an area of ...

  A = (7.25 cm)(3.25 cm) = 23.5625 cm^2

The middle rectangle is 12.25 cm by 7.25 cm, so its area is ...

  A = (12.25 cm)(7.25 cm) = 88.8125 cm^2

Then the total area is ...

  area = middle rectangle + 2×side wings + 2×top/bottom wings

  = 88.8125 +2(23.5625) +2(39.8125) = 215.5625 . . . cm^2

The area of the figure is about 215.6 cm^2.

Answer:

[tex]y = 25x +1950[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (30,2700)[/tex]

[tex](x_2,y_2) = (50,3200)[/tex]

Required

Determine the linear function

We start by calculating the slope (m)

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

So, we have:

[tex]m = \frac{3200 - 2700}{50 - 30}[/tex]

[tex]m = \frac{500}{20}[/tex]

[tex]m = 25[/tex]

The equation is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y - 2700 = 25(x - 30)[/tex]

[tex]y - 2700 = 25x - 750[/tex]

Make y the subject

[tex]y = 25x - 750 + 2700[/tex]

[tex]y = 25x +1950[/tex]

Answer:

  x = 2

  NK = 16

Step-by-step explanation:

The Pythagorean theorem can be used to find LN:

  LN² +LC² = NC²

  LN² = NC² -LC² = 65^2 -63^2 = 256

  LN = √256 = 16

  LN = NK = 16 . . . . each of NM, LN, NK is the inradius, so they are congruent

__

  LN = NM = 8x = 16

  x = 2

Answer:

b.

Step-by-step explanation:

1. You have the following parent function given in the problem above:

f(x)=x³ (This is the simplest form. We need to translate it 3 units left and 2 units down)

2. If you take the parent function and make y=f(x+3), then you have:

(The function is shifted 3 units left on the x-axis).

3. Then you if you make y=f(x+3)-2, as following, you obtain:

 (The function is shifted 2 units down on the y-axis).

4. Therefore, that is how you obtain the final function.

The answer is the graph shown in .b

Answer:

The other guy is wrong. The correct answer is Option C.

Step-by-step explanation:

It is a translation 2 units left, so (x+2)^2 is what you need here. It shifts up 3 units so that adds +3 on the outside. So f(x) = (x+2)^2 +3 or OPTION C

Answer:

C-D is: [tex]\mathbf{4b^4 -2a^b^2 -6b^4}[/tex]

Step-by-step explanation:

We are given:

[tex]C = 7a^4+ + 5a^2b2 - 3b^4\\D=5a^4 + 7a^2b^2 + 3b^4[/tex]

We need to find C-D.

Finding C-D we actually have to subtract D from C

So, finding C-D

[tex]C-D\\= 7a^4+ + 5a^2b2 - 3b^4-(5a^4 + 7a^2b^2 + 3b^4)\\=7a^4+ + 5a^2b2 - 3b^4-5a^4-7a^2b^2-3b^4[/tex]

Now, combining the like terms.

Like terms are those that have same variables and exponents.

In our case, [tex]7a^4\: and\: 3b^4, 5a^2b^2\: and\: -7a^b^2, -3b^4\:and\:-3b^4[/tex]

[tex]=7a^4 - 3b^4+5a^2b^2 -7a^b^2 -3b^4-3b^4\\=4b^4 -2a^b^2 -6b^4[/tex]

So, we get C-D is: [tex]\mathbf{4b^4 -2a^b^2 -6b^4}[/tex]

Answer:

His daughter has walked 13 steps

Step-by-step explanation:

Unit Conversion

Each step of the father is 65 cm long and each step of his daughter is 4 dm long.

Recalling that 1 dm = 10 cm, then each step of the daughter is 4*10 = 40 cm long.

Now we can compare both measures. When the father has walked 8 steps, this distance is 8*65 = 520 cm, and the daughter has walked 520/40 = 13 steps.

His daughter has walked 13 steps

Answer:

x=25°

Step-by-step explanation:

Using the "Z rule," m∠DCB has the same value with m∠EAD so they are both x.

Look at D, the other side should be 130° since it'll be 180 when you add 130 and 50.

in our triangle DBC we have 130° and 2x. So 2x = 50 and x=25

Answer:

[tex]\frac{x-5}{x+1}[/tex], [tex]x\neq -1, x\neq -9[/tex]

Step-by-step explanation:

x^2 + 4x - 45

= (x+9)(x-5)

x^2 + 10x + 9

= (x+9)(x+1)

So the fraction goes to

[tex]\frac{(x+9)(x-5)}{(x+9)(x+1)}[/tex] which is [tex]\frac{x-5}{x+1}[/tex].

Since the denominator cannot be 0, x^2 + 10x + 9 cannot be equal to 0. Therefore x cannot be -1 or -9.
