6x+y=4x+11y find the formula

Mathematics
1 answer:
atroni [7]3 years ago
7 0

Answer:

x=5y Hope this helped.

Step-by-step explanation:

6x+y=4x+11y

Step 1: Add -4x to both sides.

6x+y+−4x=4x+11y+−4x

2x+y=11y

Step 2: Add -y to both sides.

2x+y+−y=11y+−y

2x=10y

Step 3: Divide both sides by 2.

2x

2

=

10y

x=5y

Write a quadratic function with zeroes 0 and 8.
Jlenok [28]

Answer:

x^2-8x=0

Step-by-step explanation:

the quadratic function should be as follows:

x^2-8x=0

Now let's confirm that the zeros of the function are 0 and 8

x^2-8x=0=x(x-8)=0

Therefore we can see that if x = 0

0^2*8*0=0\\0=0

the equation is fulfilled

And we also have (x-8)

for this expresion to be equal to zero:

x-8=0\\x=8

thus, if x = 8

8^2-8*8=0\\64-64=0\\0=0

the equation is also fulfilled

The zeros of the quadratic function x^2-8x=0 are 0 and 8.

Answer:

<h3>Q 17</h3>

a is supplementary with 36 and b is supplementary with 113.

  • a = 180 - 36 = 144
  • b = 180 - 113 = 67

Correct choice is D

<h3>Q 2</h3>
  • LM = 1/2(AB + DC) = 1/2(46 + 125) = 85.5
<h3>Q 3</h3>

Diagonals of a rectangle are congruent

  • KM = LN
  • 6x + 16 = 49
  • 6x = 33
  • x = 33/6
  • x = 5.5

Correct choice is A

Determine the greatest common divisor of the elements of the set \[ s = \{ n^{13} - n \mid n \in \mathbb{z} \}. \]
Kay [80]

Answer:

2730

Step-by-step explanation:

We want to determine the greatest common divisor of the elements of the set  S = \{ n^{13} - n \mid n \in \mathbb{Z} \}.

We apply the Fermat's little theorem which states that if p is a prime number, then for any integer a, the number aᵖ − a is an integer multiple of p.

Now, n^{13} \equiv n \mod p if p-1 divides 12.

Since the  of 12 are 1,2,3,4, 6, 12, the corresponding primes are 2, 3, 5, 7, 13.

Therefore, the gcd of the elements in 2^{13}-2 and 3^{13}-3$ is 2 \cdot 3 \cdot 5 \cdot 7 \cdot 13.

2*3*5*7*13=2730

Therefore, the gcd of the elements in set S is 2730.
