#1 The first term of the sequence is 8 and the common difference is 12.
First Five Terms are:
The Sequence is (highlight one): Arithmetic or Geometric
Answer:
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.
What is a sequence ?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.

The value of x from the given angles is 6.3.
Given that, m∠4=(10x+5)° and m∠5=(20x−15)°.
What are angles of parallel lines?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.

Damon is 7 years older than his brother Mark. The sum of Damon and marks age is 29
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

[tex](2 \times 7) - (9 \times 6) = - 40[/tex]
Solve showing steps. Use Insert equation to get the symbol and Ctrl with . For exponents x2 + 3x - 4 = 0 9x2 + 12x + 4 =0 (leave answer as a fraction) x2 - 2x - 3 = 0 x2 - 6x + 9 = 0 2x2 - 4x - 3 = 0 (round to two decimal places)*
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]

can somebody please help!!! asap!! thank you, anything is appreciated!!
Answer:
I believe its true, Im reallly sorry if its wrong
Step-by-step explanation:
For the function f(x) = x + 2, find f-'(x).
[tex]f(x) = x + 2[/tex]
[tex]y = x + 2[/tex]
Subtract the sides of the equation minus 2
[tex]y - 2 = x[/tex]
So ;
[tex] {f}^{ - 1}(x) = x - 2 [/tex]

Two supplementary angles are in the ratio 2:7. Find the measure of the Acute angle.
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

The first term in an arithmetic sequence is 12. The third term in the sequence is 4. The tenth term in the sequence is -24.
A. Write the function that could be used to find the nth term of the arithmetic sequence
B. Daelyn said that the recursive formula for this sequence could be described as, “to find the next term of the sequence, add -4 to the previous term.” Do you agree or disagree that this statement is equivalent to the explicit formula that you created in part A? Explain.
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.
