Answer:

y=1/3x+7

Step-by-step explanation:

1. The given equation is y=1/3x-6 and it has to be parallel passing through (-12,3), so you just plug in the x and y values into the equation y=mx+b with 1/3 as the slope since its parallel (meaning the slope is the same for both eqts)

2. 3=1/3(-12)+b

3. 3=-4+b

4. 7=b

5. So, the equation is y=1/3x+7

5/7=        -----------

Answer:

x = 13

Step-by-step explanation:

A linear pair of angles sum to 180° , then

2x + 9 + 10x + 15 = 180 , that is

12x + 24 = 180 ( subtract 24 from both sides )

12x = 156 ( divide both sides by 12 )

x = 13

Answer:

[tex]\frac{5k -6}{10}[/tex]

Answer:

1/5k + 3/5

Step-by-step explanation:

2/5 * 2/2 = 4/10

4/10k + 1/10k = 5/10k = 1/2k

1/2k + 3/5

Lets find out slope

[tex]\\ \sf\longmapsto \dfrac{19-0}{0-(-5)}[/tex]

[tex]\\ \sf\longmapsto \dfrac{19}{5}[/tex]

Now

[tex]\\ \sf\longmapsto y=mx+b[/tex]

Answer:

$180

Step-by-step explanation:

Interest for 1 year = 10% of $300

Interest for 6 years

= (10% × 6) of $300

= 60% of $300

= (60/100) × $300

= 60 × $3

= $180

So, he will earn $180 as interest in 6 years.

The independent variable, x, represents the number of questions Riley answered correctly, and the dependent variable is the score, because the score depends on the number of questions Riley answered correctly. A function relating these variables is R(x) = [3x] So R(23) = [69], meaning 23 correct answers will give a score of 69.

In an experiment, there are two (2) main types of variables and these include:

An independent variable can be defined as the variable that is being manipulated by an experimenter or researcher. This ultimately implies that, it is typically considered to be the cause in an experiment and represented by x.

In this scenario, we can infer and logically deduce that the independent variable, x, represents the number of questions Riley answered correctly, and the dependent variable is the score, because the score depends on the number of questions Riley answered correctly. A function relating these variables is R(x) = [3x] So R(23) = [69], meaning 23 correct answers will give a score of 69.

Answer:

2

Step-by-step explanation:

2x(5+4)=(_x5)+(_x4)

lets start with 2x(5+4)

(5+4)=9

so we are left with 2x9

2x9=18

so now we have 18=(_x5)+(_x4)

lets try 2 for the blank spaces

18=(2x5)+(2x4)

2x5=10

2x4=8

10+8=18

2x(5+4)=(2x5)+(2x4)

Answer:

Part 5.1.1:

[tex]\displaystyle \cos 2A = \frac{7}{8}[/tex]

Part 5.1.2:

[tex]\displaystyle \cos A = \frac{\sqrt{15}}{4}[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaystyle \sin 2A = \frac{\sqrt{15}}{8}[/tex]

Part 5.1.1

Recall that:

[tex]\displaystyle \sin^2 \theta + \cos^2 \theta = 1[/tex]

Let θ = 2A. Hence:

[tex]\displaystyle \sin ^2 2A + \cos ^2 2A = 1[/tex]

Square the original equation:

[tex]\displaystyle \sin^2 2A = \frac{15}{64}[/tex]

Hence:

[tex]\displaystyle \left(\frac{15}{64}\right) + \cos ^2 2A = 1[/tex]

Subtract:

[tex]\displaystyle \cos ^2 2A = \frac{49}{64}[/tex]

Take the square root of both sides:

[tex]\displaystyle \cos 2A = \pm\sqrt{\frac{49}{64}}[/tex]

Since 0° ≤ 2A ≤ 90°, cos(2A) must be positive. Hence:

[tex]\displaystyle \cos 2A = \frac{7}{8}[/tex]

Part 5.1.2

Recall that:

[tex]\displaystyle \begin{aligned} \cos 2\theta &= \cos^2 \theta - \sin^2 \theta \\ &= 1- 2\sin^2\theta \\ &= 2\cos^2\theta - 1\end{aligned}[/tex]

We can use the third form. Substitute:

[tex]\displaystyle \left(\frac{7}{8}\right) = 2\cos^2 A - 1[/tex]

Solve for cosine:

[tex]\displaystyle \begin{aligned} \frac{15}{8} &= 2\cos^2 A\\ \\ \cos^2 A &= \frac{15}{16} \\ \\ \cos A& = \pm\sqrt{\frac{15}{16}} \\ \\ \Rightarrow \cos A &= \frac{\sqrt{15}}{4}\end{aligned}[/tex]

In conclusion:

[tex]\displaystyle \cos A = \frac{\sqrt{15}}{4}[/tex]

(Note that since 0° ≤ 2A ≤ 90°, 0° ≤ A ≤ 45°. Hence, cos(A) must be positive.)

Answer:

Hope it will help you.....

Step-by-step explanation:

my answer is

P=(4,8,12,16,20)

Q=(5,10,15,20)

The set for P and Q will be {4, 8, 12, 16, 20} and {5, 10, 15, 20}, respectively.

Sets are groups of clearly specified components. The number of items in a finite set is denoted by a curly bracket.

P = {x:x is a multiple of 4, x ≤ 20}

Then the set for P is given as,

P = 5 {4, 8, 12, 16, 20}

Q = (x:x is a multiple of 5, x ≤ 20 } ​

Then the set for Q is given as,

Q = 4 {5, 10, 15, 20}

Answer: y=-8

Step-by-step explanation:

If the slope is zero that means that the line does not go up (or have any rise) and therefore must be a horizontal line. Since it passes through the point (3,-8), the equation has to be y=-8.

The following correct answer is c.

This I because when you translate using this, you first start with the point (0,0), translate that point down 3 (-3 means down three when outside parenthesis) and translate it to the right 4 units (this shown in a paraptosis, and when you move to the right you say -4, but if you move to the left you say +4)

729x/64

Step-by-step explanation:

Answer:

Its 48 °

Since its a triangle, the total angle will be 180°

So,

x° + 42°+90°=180°(90° as one angle in triangle is 90°)

x°=180°-90°-42°

x°=48°

Answer: 48º c:

Step-by-step explanation:  So basically the angle at the top, lets call it A, is 42º. And the angle at the bottom right, is a right angle, which is 90º. We know this by the square at the angle. If we call this angle B, then through the fact that triangles will always have a combined angle measuremnt of 180º, we can do a + b + x = 180, which will be 42 + 90 = 132, 180 - 132 = 48 :)
