8 0

Answer:

(8,0)

Step-by-step explanation:

First equation

2 x- 4y = 32

2 x = 32 + 4 y

x = 32 + 4 y DIVIDED BY 2

x = 32/ 2 + 4 y/ 2

x = 16 + 2 y

Second equation

8 x − 8 y = 96

Factorize

8 ( x − y ) = 96

Transfer the 8 and put value of x

16 + 2 y − y = 96 /8

16 + y = 12

y = 12 − 16

y = − 4

Get the value of x

x = 16 + 2 y

x = 16 + 2 × − 4

x = 16 + ( − 8 )

x = 8

Prove that if a and b are positive integers whose sum is a prime p, their greatest common divisor is 1.

Tasya [4]

Proof by contadiction.

Let assume there exist such positive integers $a$ and $b$ whose sum is a prime number $p$ , that their greatest common divisor is greater than 1.

$a,b\in\mathbb{Z^+}\\d=\text{gcd}(a,b)>1\\\\a=de\\b=df\\e,f\in\mathbb{Z^+}\\\\a+b=p\\de+df=p\\d(e+f)=p\\$

Since $p$ is a prime number and $d>1$ , then $d=p \wedge e+f=1$ , but we assumed earlier that $e,f\in\mathbb{Z^+}$ , and there are no two positive integers that sum up to 1.

Which of the function below could possibly have created this graph ?

lina2011 [118]

ANSWER

$f(x) = - {x}^{4} + {x}^{3} + 3 {x}^{2}$

EXPLANATION

The given graph rises on the left and falls on the right.

This implies that the degree of the function is even.

Since the graph opens downward, the coefficient of the leading term must be negative.

The graph graph of the function also has 3 intercepts with one of them having an even multiplicity.

This means that the degree must be 4.

Therefore the last choice is correct.

A. Complete the table if y varies

serious [3.7K]

Direct variation is represented by the equation y = k × x and inverse variation is represented by y = k/x

Table 1:

y = k × x

30 = k × 5

30 = 5k

k = 30/5

k = 6

So,

y = 30

y = 30 k = 6

y = 30 k = 6x = 5

y = 30 k = 6x = 5Equation: y = 6x

y = k × x

y = 10 × 8

y = 80

So,

y = 80

y = 80 k = 10

y = 80 k = 10x = 8

y = 80 k = 10x = 8Equation: y = 10x

y = 3x

18 = 3x

x = 18/3

x = 6

So,

y = 18

y = 18k = 3

y = 18k = 3x = 6

y = 18k = 3x = 6Equation: y = 3x

y = 2x²

72 = 2x²

x² = 72/2

x² = 36

x = √36

x = 6

So,

y = 72

y = 72k = 2

y = 72k = 2x = 6

y = 72k = 2x = 6Equation: y = 2x²

Table 2:

y = k/x

5 = k/6

5 × 6 = k

30 = k

So,

y = 5

y = 5k = 30

y = 5k = 30x = 6

y = 5k = 30x = 6Equation: y = 30/x

y = k/x

y = 36/4

y = 9

So,

y = 9

y = 9k = 36

y = 9k = 36x = 4

y = 9k = 36x = 4Equation: y = 36/x

y = 60/x

20 = 60/x

20x = 60

x = 60/20

x = 3

So,

y = 20

y = 20k = 60

y = 20k = 60x = 3

y = 20k = 60x = 3Equation: y = 60/x

y = 24/x

y = 24/12

y = 2

So,

y = 2

y = 2k = 24

y = 2k = 24x = 12

y = 2k = 24x = 12Equation: y = 24/x
