A=|3x-6| + 2 , xeR
prove that:
A=3x-4 for every x≥2
Answer:
We know that the function IxI is such that:
IxI = x if x ≥ 0
IxI = -x if x < 0.
In this case, we have:
A = I3x - 6I + 2
If we do the same as above, we can write:
A = (3x - 6) + 2 if (3x - 6) ≥ 0
Let's look at the condition in the right, let's isolate the variable:
(3x - 6) ≥ 0
3x ≥ 6
x ≥ 6/3 = 2
Then the condition:
(3x - 6) ≥ 0
is equivalent to:
x ≥ 2
Then we can write:
A = (3x - 6) + 2 if x ≥ 2
If we simplify it further, we get:
A = 3x - 6 + 2 if x ≥ 2
A = 3x - 4 if x ≥ 2
This is what we wanted to prove.
Explain the survival of the fittest.
Answer:
Survival of the Fittest
There has been gradual evolution of life forms with new forms arising at different periods of history. Any population has built-in variations in characteristics which adapt it better to environment.The characteristics which enable some population or individuals to survive better in natural conditions (climate, food, physical factors) would out-breed others (Survival of the fittest).Adaptability is inherited and fitness is the end result of ability to adapt and get selected by nature.help plz I am being timed will give brainliest
Answer:
-3/4
Step-by-step explanation:
2 1/2 = 5/2 = 10/4
1 3/4 = 7/4
when you subtract, you add and change the sign of the second term (add the opposite)
-10/4 + 7/4 = -3/4

(8x+12)
(3x-8)
Answer:
x = 16, y = 140
Step-by-step explanation:
(8x + 12)° and (3x - 8) are adjacent angles and are supplementary, sum to 180°
8x + 12 + 3x - 8 = 180
11x + 4 = 180 ( subtract 4 from both sides )
11x = 176 ( divide both sides by 11 )
x = 16
Then
8x + 12 = 8(16) + 12 = 128 + 12 = 140
(8x + 12) and y are alternate angles and are congruent , so
y = 140

Step-by-step explanation:
5√2/2 is the value of x in the triangle.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The hypotanenuse is 5 cm
The angle opposite to right angle is 45 degrees.
As it is a right angle one angle is 90 degrees.
This is a right angled isosceles triangle whose sides are in the ratio 1:1:√2.
In an isosceles right triangle, the equal sides make the right angle. They have the ratio of equality, 1 : 1.
So 5/√2.
Multiply numerator and denominator by √2
We get 5√2/2
Hence, 5√2/2 is the value of x in the triangle.

The sequence follows a times -1 pattern: 6, -6, 6, -6. Write a formula for the (n)th term of the sequence. Your “n” term must start with 1
Answer:
The formula for the nth term of the sequence is:
[tex]a_n=a_1\cdot r^{n-1}[/tex]
Step-by-step explanation:
Given the sequence
6, -6, 6, -6
A geometric sequence has a constant ratio r and is defined by
[tex]a_n=a_1\cdot r^{n-1}[/tex]
Computing the ratios of all the terms of the adjacent terms
[tex]\frac{-6}{6}=-1,\:\quad \frac{6}{-6}=-1,\:\quad \frac{-6}{6}=-1[/tex]
The ratio of all the adjacent terms is the same and equal
so
r = -1
so substituting r = -1 and [tex]a_1=6[/tex] in the geometric sequence
[tex]a_n=a_1\cdot r^{n-1}[/tex]
[tex]a_n=6\left(-1\right)^{n-1}[/tex]
Thus, the formula for the nth term of the sequence is:
[tex]a_n=a_1\cdot r^{n-1}[/tex]

Answer:
8 bulbs
Step-by-step explanation:
In the model, each + represents a dollar
4 +s for the shipping cost, 20 +s for the total cost.
Therefore we have 2x (since each bulb is $2) + 4 = 20
2x = 16
x = 8
Step-by-step explanation:
x is the number of bulbs.
We have $2x + $4 = $20.
=> $2x = $16, x = 8.
Hence Sheila can order 8 flower bulbs.

Michela’s skateboard ramp is at an incline of 40°. When she attempts a trick on the ramp, she finds that it is too steep. She adjusts the ramp to half of the original incline. What is the measurement of the incline now?
Answer:
22.7604763 degrees
Step-by-step explanation:
Note that the answer is NOT 20 degrees.
She adjusted the ramp to half the original incline
Therefore we have tan 40 = x = 0.839099631.
We want an incline of y degrees where tan y = x/2 = 0.839099631/2 = 0.419549815
Taking the arctan of both sides, we get
y = arctan(0.419549815) = 22.7604763 degrees

Triangle P R Q is shown. The length of P R is 4, the length of R Q is 6, and the length of P Q is 5. Law of cosines: a2 = b2 + c2 – 2bccos(A) Find the measure of AngleQ, the smallest angle in a triangle whose sides have lengths 4, 5, and 6. Round the measure to the nearest whole degree. 34° 41° 51° 56°
Answer:
41°
Step-by-step explanation:
Using cosine rule : since the 3 sides are given
p = 6 ; q = 4 ; r = 5
q² = p² + r² - 2prCosQ
2prCosQ = p² + r² - q²
COS Q = (p² + r² - q²) / 2pr
Cos Q = (6² + 5² - 4²) / 2*6*5
Cos Q = 45 / 60
Cos Q = 0.75
Q = Cos^-1 (0.75)
Q = 41.409622
Q = 41° ( nearest degree)

Area is the amount of space that a two dimensional object or figure occupies.
The area of the big rectangle = length * width = 12 * 4 = 48 ft²
Area of hole = length * width = 2 * 2 = 4 ft²
Amount of carpet required = 48 ft² - 4 ft² = 44 ft²

if perimeter and length of a rectanguar field are 154m and 42m respectively, find its breadth
Answer:
Assuming you mean width not breadth (What is that)
The width would be: 35m
Step-by-step explanation:
Now its pretty staight forward
We know that the length is 42m
And the permineter is 154m
We know that the perimeter is the 2 widths and 2 lengths all added up to each other (basically very side added up)
An eaution could be used like, 2w+2l=154
We know length is 42 so
2w+2*42=154
Now just solve for W
2*42=84
2w+84=154
154-84= 70
70=2w
70/2=35
w=35

After 11months, he weighed 140 kilograms. He gained weight at a rate of 5.5 , point, 5 kilograms per month. Let yyy represent the sumo wrestler's weight (in kilograms) after xxx months.
Answer:
y = 5.5x + 79.5
Step-by-step explanation:
Given that:
Weight gained after 11 months = 140 kg
Rate of weight gain = 5.5kg per month
Weight in kg after x months = y
Representing the equation in the form:
y = mx + c
m = rate of water gain = slope = 5. 5
.the intercept c, can be obtained thus ;
x = 11 ; y = 140
140 = 5.5(11) + c
140 = 60.5 + c
140 - 60.5 = c
79.5 = c
Hence,
y = 5.5x + 79.5

A hair stylist offers haircuts and hair coloring to his customers. A haircut costs $18 and hair coloring costs $42. Yesterday, the hair stylist had 12 customers and earned a total of $288. How many of the hair stylists customers received hair coloring yesterday
Answer:
haircut =9 and hair color= 3
Step-by-step explanation:
Step one:
GIven data
let the haircut be x
and hair color be y in numbers.
so
18x+42y=288------------1
x+y=12---------------------2
from 1
x=12-y, put this in 2, we have
18(12-y)+42y=288
216-18y+42y=288
collect like terms
24y=288-216
24y=72
divide both sides by 24
y=72/24
y=3
put y= 3 in 2
x+3= 12
x= 12-3
x=9
