if x²+y²=6xy then prove that 2log(x+y)=logx+logy+3log2
Answer:
Given that
x² + y² = 6xy
or, (x + y)² - 2xy = 6xy
or, (x + y)² = 8xy
or, (x + y)² = 2³xy
Taking (log) in both sides, we get
log (x + y)² = log (2³xy)
or, 2 log (x + y) = log (2³) + logx + logy
or, 2 log (x + y) = 3 log2 + logx + logy

-4.5x > -21
Can someone help me ASAP
Step-by-step explanation:
-4.5 x > -21
4.5 = 9/2
WHEN DIVIDING INEQUALITIES WITH NEGATIVE SIGNS, THE GREATHER THAN SIGN WILL CHANGE TO LESS THAN.
-9/2x > - 21
Divide both sides by 9/2 or 4.5
-9/2x / - 9/2 > - 21 / - 9/2
x < 21 × 2/9
x < 7 × 2/3
x < 14/3
x < 4.66666667

Keith and his 6 friends are taking a trip. The total cost of the trip is $1,145.55. The total cost of the tickets for the amusement park was $341.25. The total cost of three hotel rooms was $454.65. The total cost for the show they were going to see was $153.65. The rest of the money they paid was used to purchase gas for their trip. Use this information to answer the questions below.
Answer and explanation:
Question is incomplete
Question will likely ask how much is the rest of the money paid for gas.
We use algebra to find how much is the rest of the money paid for gas
So given
total cost of the trip = $1,145.55
total cost of tickets for amusement park = $341.25
The total cost of three hotel rooms = $454.65
total cost for the show they were going to see = $153.65
Let's call rest of money spent on gas x
Hence the equation for total cost with all expenditures,
$341.25+$454.65+$153.65+x=$1,145.55
Solve for x
$949.55+x=$1145.55
x=$1145.55-$949.55
x= $196
Therefore amount spent on gas for the trip =$196

purchase furniture of rs.50000 at 10% discount (accounting equation
Answer:
5000
Step-by-step explanation:
50000 / 10= 5000
Cost of the furniture of 50000 rupees with 10% discount is 45000 rupees
What is Discount?A deduction from the usual cost of something
Here Cost of the furniture = 50000 rupees
Discount = 10%
Then the discount price is = total cost × 10%
[tex]50000(\frac{10}{100})=5000[/tex] rupees
Then the purchased amount = Total price - Discount

Answer:
Angle sum property of a triangle is 180°
So,
Angle T + Angle U + Angle V =180°
(5x +7) + (2x + 7) + (6x + 10) = 180 °
5x + 7 + 2x + 7 + 6x + 10 = 180°
13x + 24 = 180 °
13x = 180 - 24
13x = 156
x = 156/13
X = 12
Angle U = 2x + 7 = 24 + 7 = 31
Angle T = 5x +7 = 60 + 7 = 67
Angle V =6x + 10 =72 +10 =82
For second questionx + x + x =3x
And according to the theorem of triangle of sum
3x = 180 °
x = 180 / 3
x = 60°
In first box u have to write 180 °
And in second one 60°

Just find the equation of the line, which is y = 1/3x -3, and then determine what the symbol is going to be. Since the line is dotted, it will either be < or >. When the shaded area is on top of the line, it's >. Remember that by saying left on the bottom or right on top.

What slope would make the lines
parallel?
y = -3x + 9
y = [?]x + 4
Answer:
- 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 9 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + 4 ← is the equation of a parallel line

if f(x)= x^2 and g(x) = 4f (x)-1 then which of the following is the value of g (-3)
view image below to see answer choices
Answer:
27Step-by-step explanation:
Given
f(x)= x^2-2 and g(x) = 4f (x)-1
g(x) = 4(x^2-2) - 1
g(x) = 4x²-8-1
g(x) = 4x²-9
Get g(-3):
g(-3) = 4(-3)²-9
g(-3 = 4(9) - 9
g(-3) = 36-9
g(-3) = 27

Describe how to create an equivalent equation from an equation that has fractions or decimals. Explain how to decide what numbers to use to multiply. Also, explain any other important things to remember when using this process.
Answer:
i hope this helps :)
Step-by-step explanation:
So, with an equation with decimals, we can use the same method we used to clear fractions—multiply both sides of the equation by the least common denominator. Look at the decimals and think of the equivalent fractions. Notice, the LCD is 100. By multiplying by the LCD, we will clear the decimals from the equation.
Answer: If the equation have fractions in it, then find the LCM of all the denominators.Then multiply both side of the equation by that LCM.
If the equation has decimal, then count the maximum number of places after decimal. Then multiply by "1 and then that many zeros".
Steps: If the equation have fractions in it, then find the LCM of all the denominators.Then multiply both side of the equation by that LCM.
For example:
[tex]\frac{2}{3}x-\frac{5}{4}=\frac{1}{2}[/tex]
Here denominators are 3,4 and 2. So the LCM of them is = 12
Multiply both sides by 12.
[tex]12(\frac{2}{3}x-\frac{5}{4})=12(\frac{1}{2})\\8x-15=6[/tex]
If the equation has decimal, then count the maximum number of places after decimal. Then multiply by "1 and then that many zeros".
For example: 0.324x - 0.92 = 0.526
Here maximum number of places after decimal is = 3.
So we will multiply both sides by 1000.
1000(0.324x - 0.92) = 1000(0.526)
324x - 920 = 526

Given :
Lulu tells her little brother, Jack, that she is holding 20 coins, all of which are either dimes or quarters.
They have a value of $4.10. She says she will give him the coins if he can tell her how many of each she is holding.
To Find :
How many dimes and quarters in Lulu holding?
Solution :
4.10 dollar = 410 cents
Let, number of dimes and quarter are x and y.
So, x + y = 20 ...1)
Also, 10x + 25y = 410 ...2)
Putting value of 1) in equation 2), we get :
10x + 25( 20 - x ) = 410
10x + 500 - 25x = 410
15x = 90
x = 6
y = 14
Therefore, number of dimes and quarters are 6 and 14 respectively.
Hence, this is the required solution.

Select the correct answer. Which statement is true about the extreme value of the given quadratic equation? y = -3x2 + 12x − 33 A. The equation has a maximum value with a y-coordinate of -21. B. The equation has a minimum value with a y-coordinate of -21. C. The equation has a minimum value with a y-coordinate of -27. D. The equation has a maximum value with a y-coordinate of -27.
Step-by-step explanation:
y = -3x² + 12x - 33
y = -3[x² - 4x + 11]
y = -3[(x - 2)² + 7]
Since the coefficient of x² is negative, the curve concaves downwards and has an absolute maximum value. This happens when x = 2, y = -21.
Therefore the correct option is A.
