Answer:

D

Step-by-step explanation:

First of all, you are moving right. That means that something gets added or subtracted from the x

To move right whatever number units you move right, will be subtracted from the x.

A and B are are both wrong. It is really the y that the +/- ten changes.

C is wrong because you are moving left, not right.

D is the answer. It is not intuitive, but it is how how move right.

Answer:

202°

Step-by-step explanation:

Arc I K ≅ Arc J K, Given that mArc I K = (11x + 2)°, and mArc J K = (12x – 7)°. SInce Arc I K ≅ Arc J K, then;

(11x + 2)° = (12x – 7)°

Collect the like terms

11x - 12x = -7 - 2

-x = -9

x = 9

Arc IJK = 11x+2 + 12x - 7

Arc IJK = 23x-5

Arc IJK  = 23(9)-5

Arc IJK  = 207-5

Arc IJK  = 202°

Hence the measure of Arc IJK is 202°

Answer:

Pam: $181

Amanda: $362

Julie: $452

Step-by-step explanation:

(What does Mike have to do with this problem?)

Let a = Amanda's pay

Let p = Pam's pay

Let j = Julie's pay

"Amanda made twice what Pam earned"

a = 2p

"Julie made $90 more than Amanda"

j = a + 90

j = 2p + 90

Pam earned p

Total salary

a + p + j = 2p + p + 2p + 90

Total salary

$995

2p + p + 2p + 90 = 995

5p = 905

p = 181

a = 2p = 2(181) = 362

j = 2p + 90 = 362 + 90 = 452

Answer:

Pam: $181

Amanda: $362

Julie: $452

Answer:

2x^2+10x+2

Step-by-step explanation:

12x^2 +5x+1 - ( 10x^2 -5x-1)

Distribute the minus sign

12x^2 +5x+1 -  10x^2 +5x+1

Combine like terms

2x^2+10x+2

The  number - 7/5 is LESS than -1 1/5

because -7/5 lies GREATER 5-1 /1 on a vertical number line.

Answer:

f(-6) = -12

Step-by-step explanation:

If you immediately plug in x=-6 and solve it (x^2-36)/x+6, you will not get the right answer.

You need to first expand the perfect square on the numerator (x^2-36) into (x-6)(x+6).

With the perfect square expanded, notice how you have the term (x+6) on both the numerator and denominator. You can cancel out both terms, and you will be left with (x-6).

Now you can plug in x=-6, which will give you -12.

Answer:

The set [tex]S[/tex] of non-negative integers in the inequality [tex]2x < 4[/tex] is

[tex]S = \{0, 1\}[/tex]

Step-by-step explanation:

The non-negative integers are given as [tex]\mathbb{Z}_{\ge 0} = \{ 0, 1, 2, \ldots \}[/tex]

For the inequality [tex]2x < 4[/tex], we have

[tex]2x < 4 \implies x < \dfrac{4}{2} \implies x < 2[/tex]

Therefore,

[tex]x\in \mathbb{R}:x\in(\infty, 2)[/tex]

Note: 2 is not included

The integers are

[tex]\ldots -2, -1, 0, 1[/tex]

And the non-negative integers are

[tex]0, 1[/tex]

Dado :

Para pedidos de hasta una docena; par de pantimedias Glamour Costo S / 5

Para pedidos de más de una docena; par de pantimedias Glamour Costo S / 3

Función de costo:

Para x ≤ 12

Costo, C = 5x

Para x> 12

Costo, C = 3x

Costo de 5 pedidos:

x = 5

Costo, C = 5 (5) = S / 25

Costo de 15 pedidos:

x = 15

Costo, C = 3 (15) = S / 45

Costo de 25 pedidos:

x = 25

Costo, C = 3 (25) = S / 75

Answer:

C

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{16}{AC}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

AC = 16[tex]\sqrt{2}[/tex] → C

The measure of the side of a triangle AC is [tex]16\sqrt{2}[/tex] cm.

Given that, ∠45° and AB=16 cm.

We need to find the measure of side AC.

There are three steps:

Now, [tex]sin \ C=\frac{AB}{AC}[/tex] (∵ sinα=Opposite/Hypotenuse)

[tex]sin 45^{o} =\frac{16}{AC} \\[/tex]

[tex]\implies \frac{1}{\sqrt{2} } =\frac{16}{AC}[/tex]

[tex]\implies AC=16\sqrt{2}[/tex] cm

Therefore, the measure of the side of a triangle AC is [tex]16\sqrt{2}[/tex] cm.
