Answer:
i) y∝x => y = kx and k = 2.5
ii) When x = 7, y is 17.5
Step-by-step explanation:
If y is directly proportional to x then according to the question
y∝x which means y =kx where k is any constant
From the above example
8y=20x comparing it with y = kx
y = (20/8)x
y = 2.5x
Here k = 2.5
i) y∝x => y =2.5x
ii) if x=7 then y = ?
From above
y=2.5x
Put x = 7
y = 2.5 x 7
y = 17.5

I have to do a Hinduism poster for the teacher who does not really like me so can anybody I really don't care who give me tips on what should I put in it??????????????????
Answers
- Hindu symbols
- This will be a great start to a Hindu themed poster as the symbols mean a lot, and you could even put a message with the symbols
- Ganesha (sacred elephant) or Hanuman (The monkey god)
- Putting sacred animals in the poster will really bring out the theme and idea of the poster itself.
- A temple
- Putting a temple in the poster will overall represent the theme of this poster, as Hindu's spend a lot of time in their temple's
- Murti (statue or image of the god being worshipped0
- To top it off add a religious symbol in there
Hinduism: A major religion started in South Asia, which was developed by Vedic Religion
95% of the Hindus live in India.
Over 900 million people are considered to be Hindu.

−2x − 10 = 15 I'm really un smart
Answers
Answer:
x = -12.5
Step-by-step explanation:
your goal is to get x alone so
-2x - 10 = 15
(add ten to both sides)
-2x = 25
(divide -2 to both sides)
x = -12.5
remember that whatever u do to one side of the equation, you have to do to the other so they even out!

Step-by-step explanation:
Hello There!
It says the tree has a cone like structure
The formula for volume of a cone is
[tex]V=\pi r^2\frac{h}{3}[/tex]
where r = radius and h = height
note it says to use 3.14 for pi
so given the dimensions all we have to do is plug in the values into the formula
[tex]V=3.14*2^2*\frac{6}{3}\\2^2=4\\4*3.14=12.56\\\\\frac{6}{3} =2\\2*15.56=25.133[/tex]
Our last step is to round to the nearest foot
So we can conclude that the tree has a volume of 25.13ft³

Answer:
2x = 6
Step-by-step explanation:
Simplify the following algebraic expressions.
- 6x + 5 + 12x -6
2(x - 9) + 6(-x + 2) + 4x
3x2 + 12 + 9x - 20 + 6x2 - x
(x + 2)(x + 4) + (x + 5)(-x - 1)
1.2(x - 9) - 2.3(x + 4)
(x2y)(xy2)
(-x2y2)(xy2)
Solution
Group like terms and simplify.
- 6x + 5 + 12x -6 = (- 6x + 12x) + (5 - 6)
= 6x - 1
Expand brackets.
2(x - 9) + 6(-x + 2) + 4x = 2x - 18 - 6x + 12 + 4x
Group like terms and simplify.
= (2x - 6x + 4x) + (- 18 + 12) = - 6
Group like terms and simplify.
3x2 + 12 + 9x - 20 + 6x2 - x
= (3x2 + 6x2) + (9x - x) + (12 - 20)
= 9x2 + 8x - 8
Expand brackets.
(x + 2)(x + 4) + (x + 5)(- x - 1)
= x2 + 4x + 2x + 8 - x2 - x - 5x - 5
Group like terms.
= (x2 - x2) + (4x + 2x - x - 5x) + (8 - 5)
= 3
Expand and group.
1.2(x - 9) - 2.3(x + 4)
= 1.2x - 10.8 - 2.3x - 9.2
= -1.1x - 20
Rewrite as follows.
(x2y)(xy2) = (x2 x)(y y2)
Use rules of exponential.
= x3 y3
Rewrite expression as follows.
(-x2y2)(xy2) = -(x2 x)( y2 y2)
Use rules of exponential.
= - x3 y4
Simplify the expressions.
(a b2)(a3 b) / (a2 b3)
(21 x5) / (3 x4)
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
(4x - 12) / 4
(-5x - 10) / (x + 2)
(x2 - 4x - 12) / (x2 - 2 x - 24)
Solution
Use rules of exponential to simplify the numerator first.
(a b2)(a3 b) / (a2 b3) = (a4 b3) / (a2 b3)
Rewrite as follows.
(a4 / a2) (b3 / b3)
Use rule of quotient of exponentials to simplify.
= a2
Rewrite as follows.
(21 x5) / (3 x4) = (21 / 3)(x5 / x4)
Simplify.
= 7 x
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
Multiply terms in numerator and denominator and simplify.
(6 x4)(4 y2) / [ (3 x2)(16 y) ] = (24 x4 y2) / (48 x2 y)
Rewrite as follows.
= (24 / 48)(x4 / x2)(y2 / y)
Simplify.
= (1 / 2) x2 y
Factor 4 out in the numerator.
(4x - 12) / 4 = 4(x - 3) / 4
Simplify.

Factor -5 out in the numerator.
(-5x - 10) / (x + 2) = - 5 (x + 2) / (x + 2)
Simplify.
= - 5
Factor numerator and denominator as follows.
(x2 - 4x - 12) / (x2 - 2x - 24) = [(x - 6)(x + 2)] / [(x - 6)(x + 4)]
Simplify.
= (x + 2) / (x + 4) , for all x not equal to 6
Solve for x the following linear equations.
2x = 6

Believe me, it's worth the extra work to do this!!
Given the sequence -3, -6, -12, -24, you can easily see that the first term,
a is -3. The common factor is 2. Note how (-3)*2=-6, and so on.

So, a = -3 and r=2.
