Arithmetic

Step-by-step explanation:

Since the common difference remains the same between terms, its arithmetic!

The first five terms of the given AP is 8, 20, 32, 44 ,56.

A sequence is a list of numbers written in form of a constant difference or ratio.

According to the given question the given question the first term (a₁) of the AP is 8 and the common difference (d) is 12.

This is an AP because given in the question it self of common difference.

We know than n term of an AP is aₙ = a₁ + (n-1)d.

Given,

a₁ = 8.

a₂ = 8 + (2-1)12

a₂ = 8 + 12

a₂ = 20.

Similarly.

a₃ = 32.

a₄ = 44.

a₅ = 56.

Step-by-step explanation:

plug in the answer

The value of x from the given angles is 6.3.

Given that, m∠4=(10x+5)° and m∠5=(20x−15)°.

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

From the figure given below,

m∠4+m∠5 = 180° (Adjacent angles adds upto 180 degree)

⇒ (10x+5)°+(20x−15)° = 180°

⇒ 10x+20x+5-15 = 180°

⇒ 30x-10 = 180°

⇒ 30x=190

⇒ x=190/30

⇒ x=6.3

Therefore, the value of x from the given angles is 6.3.

Answer:

I believe its true, Im reallly sorry if its wrong

Step-by-step explanation:

Answer:

A-> a(n)=a+(n-1)d

B-> Yes, I do agree

Step-by-step explanation:

A=   a+(n-1)d

where a=the first term

           n=the term's location

           d= the difference between two adjacent terms

B= I agree

a3=12+2d=4.........equation 1

          2d=-8

             d=-4

a10=12+9d=-24.....equation 2

            9d=-36

              d=-4

Hence, to find the next term of the sequence, add -4 to  the previous term.

Answer: the range is 41, when finding the range you're finding the difference between the largest number and the smallest number so 42-X=1=41

Step-by-step explanation: when finding the domain you're simplifying the number, but since 41 can't be simplified it remains as 41

... The End

Answer:

Damon is 18, Damon's brother is 11 years old.

Step-by-step explanation:

So, the total age of them both is 29. Damon is 7 years older, so we use 29-7=22. Now, 22 is Damon's brother's age times 2, so we use 22/2=11. 11 is Damon's age is 11+7=18, and His brothers age is 11.

Answer:

daman's age = (7+x)

let his brother's age be 'x'

according to the question,

(7+x) + x =29

7+x+x = 29

2x = 29 - 7

2x = 22

x = 22÷2

x = 11 = age of daman's brother

age of daman = 7+11 = 18

Answer:

40°

Step-by-step explanation:

Ratio of two supplementary angles = 2 : 7

The angles are 2x , 7x

2x + 7x = 180  {Supplementary}

       9x = 180

         x = 180/9

x = 20

Acute angle = 2x = 2*20 = 40

Let's solve your inequality step-by-step.

122<−2(8x+3)

Step 1: Simplify both sides of the inequality.

122<−16x−6

Step 2: Flip the equation.

−16x−6>122

Step 3: Add 6 to both sides.

−16x−6+6>122+6

−16x>128

Step 4: Divide both sides by -16.

−16x /−16 > 128 /−16

x<−8

Step-by-step explanation:

Here all the given equations are in the form of

[tex]ax^2+bx+c=0[/tex]

The value of [tex]x[/tex] can be determined by the perfect square method as follows:

[tex]ax^2+bx+c=0[/tex]

[tex]\Rightarrow x^2+\frac{b}{a}+\frac{c}{a}=0[/tex]

[tex]\Rightarrow x^2+2\times\frac{b}{2a}+\left(\frac{b}{2a}\right)^2-\left(\frac{b}{2a}\right)^2+\frac{c}{a}=0[/tex]

[tex]\Rightarrow \left(x+\frac{b}{2a}\right)^2=\left(\frac{b}{2a}\right)^2-\frac{c}{a}[/tex]

[tex]\Rightarrow x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\;\cdots(i)[/tex]

Now, for [tex]x^2+3x-4=0[/tex]

[tex]a=1, b=3, c=-4[/tex]

So, from equation (i)

[tex]x=\frac{-3\pm\sqrt{3^2-4\times1\times(-4)}}{2\times1}[/tex]

[tex]\Rightarrow x=\frac{3\pm\sqrt{9+16}}{2}[/tex]

[tex]\Rightarrow x=\frac{3\pm5}{2}[/tex]

[tex]\Rightarrow x=\frac{3+5}{2},\frac{3-5}{2}[/tex]

[tex]\Rightarrow x= 4, -1[/tex]

Similarly, for [tex]9x^2+12x+4=0[/tex]

[tex]a=9, b=12, c=4[/tex]

So, from equation (i)

[tex]x=\frac{-12\pm\sqrt{12^2-4\times9\times4}}{2\times9}[/tex]

[tex]\Rightarrow x=\frac{-12\pm0}{18}[/tex]

[tex]\Rightarrow x=\frac{-2}{3}[/tex]

For [tex]x^2-2x-3=0[/tex]

[tex]a=1, b=-2, c=-3[/tex]

[tex]x=\frac{-(-2)\pm\sqrt{(-2)^2-4\times1\times(-3)}}{2\times1}[/tex]

[tex]\Rightarrow x=\frac{2\pm\sqrt{16}}{2}[/tex]

[tex]\Rightarrow x=\frac{2\pm4}{2}[/tex]

[tex]\Rightarrow x=\frac{6}{2},\frac{-2}{2}[/tex]

[tex]\Rightarrow x=3.00, -1.00[/tex]

For [tex]x^2-6x+9=0[/tex]

[tex]a=1, b=-6, c=9[/tex]

[tex]x=\frac{-(-6)\pm\sqrt{(-6)^2-4\times1\times9}}{2\times1}[/tex]

[tex]\Rightarrow x=\frac{6\pm0}{2}[/tex]

[tex]\Rightarrow x=3.00[/tex]

For [tex]2x^2-4x-3=0[/tex]

[tex]a=2, b=-4, c=-3[/tex]

[tex]x=\frac{-(-4)\pm\sqrt{(-4)^2-4\times2\times(-3)}}{2\times2}[/tex]

[tex]\Rightarrow x=\frac{4\pm\sqrt{40}}{4}[/tex]

[tex]\Rightarrow x=\frac{4\pm2\sqrt{10}}{4}[/tex]

[tex]\Rightarrow x=\frac{4+2\sqrt{10}}{4},\frac{4-2\sqrt{10}}{4}[/tex]

[tex]\Rightarrow x=2.58, -0.58[/tex]

It would be A.

Step-by-step explanation:

You can simply add the numbers to coordinates to see if matches.

For example, if you add the x + 2 to -3 and 2, its -1 and 4. Then if you add y+3 to -1 and 1, it's 2 and 4. I hope that makes sense :)
