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

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.

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]

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

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.

Answer: D 1 hour 56 minutes
Answer:
D. 1 hour 56 minutes
Step-by-step explanation:
Well, if you add 2 hours to 12:14, it would be 2:14, so you know it's less than 2 hours. B and D are the only choices that have 1 hour. So, if Aaron left at 2:10, you have to subtract 4 minutes from 2 hours. That would be 1 hour and 56 minutes Aaron spent at the mall.

In Aunt Peggy’s backyard there are cows and chickens. There are 20 more chickens than cows. The total number of legs is 130. How many chickens and how many cows are there? (Each cow has 4 legs, each chicken has 2 legs.) PLZ HELP! Will mark brainliest
Answer:
There are 15 cows and 35 chickens
Step-by-step explanation:
So first you take 20 and multiply it by two since there are two legs on each chicken. You get 40.
Then you subtract 40 from 130. You get 90.
Since the cow has double the legs of the chicken, you can count the cow as two chicken.
You divide 90 by 3. You get 30.
To get the number of chicken you divide 30 by 2 and you get 15.
You add 15 and 20 together and you get 35 chickens.
To get the number of cows you divide 30 by 2 and you get 15.
So you have your answer. 35 chicken and 15 cows.
