Step-by-step explanation:

Answer:

x=8 and y=−3

Answer:

x = -5

Step-by-step explanation:

-3x - 4 = 11

add 4 to both sides

-3x = 15

divide by -3

x= -5

plug it in to check:

-3 (-5) - 4 = 11

-3 times -5 is 15

15 - 4 = 11

Answer:

Step-by-step explanation:

The linear equation for the function is f ( x ) = y = ( 2/3 ) x - 3

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation be f ( x ) = y

Now , the value of the function f ( 3 ) is given in the equation as

f ( 3 ) = -1

And the value of the function f ( 6 ) is given in the equation as

f ( 6 ) = 1

So ,

when x = 3 , y = -1

and when x = 6 , y = 1

Now , we have two points A ( x₁ , y₁ ) and B ( x₂ , y₂ )

A ( x₁ , y₁ ) = A ( 3 , -1 )

B ( x₂ , y₂ ) = B ( 6 , 1 )

Now ,

To find the slope of the equation , we use

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values , we get

Slope m = ( 1 - ( -1 ) ) / ( 6 - 3 )

              = 2 / 3

Now , the equation of line will be y - y₁ = m ( x - x₁ ) ,

So , substituting the value of m , we get

y - ( -1 ) = ( 2/3 ) ( x - 3 )

y + 1 = ( 2/3 )x - 2

Subtracting 1 on both sides , we get

y = ( 2/3 )x - 3

Therefore , the equation of line will be y = ( 2/3 )x - 3

Hence , The linear equation for the function is f ( x ) = y = ( 2/3 ) x - 3

Answer:

x = -2.5 + 3y

Step-by-step explanation:

Simplifying

12y + -4x = 10

Reorder the terms:

-4x + 12y = 10

Solving

-4x + 12y = 10

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12y' to each side of the equation.

-4x + 12y + -12y = 10 + -12y

Combine like terms: 12y + -12y = 0

-4x + 0 = 10 + -12y

-4x = 10 + -12y

Divide each side by '-4'.

x = -2.5 + 3y

Simplifying

x = -2.5 + 3y

Answer:

Yes, it does form a triangle

Step-by-step explanation:

According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that the given side lengths DO form a triangle. 6.4+12.9=19.3 which is more than 14.2.

Step-by-step explanation:

Prime numbers : numbers divisible only by 1 and itself

They include ;

{2, 3, 5, 7 , 11}

Largest prime number that is a factor of 35

Factor of 35

35 = 1 * 5 * 7

Largest prime number , multiple of 35 = 7

Factors of 15

15 = 1 * 3 * 5

Smallest prime number, multiple of 15 = 3

7 * 3 = 21

Is b) Step-by-step explanation:

The length and the width of the rectangular garden will be ( x + 21) and x - 2 respectively.

Quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given that the area of a rectangular garden is represented by the polynomial is shown x² + 19x - 42. The length and the width will be calculated by factorizing the given quadratic equation.

x² + 19x - 42 = 0

x² -21x + 2x - 42 = 0

x ( x - 21 ) + 2 ( x - 21 ) = 0

( x + 2 ) ( x - 21 ) = 0

Therefore, the length and the width of the rectangular garden will be ( x + 21) and x - 2 respectively.

Answer:

1 + ln 2 - ln x

Step-by-step explanation:

ln ( 2e /x)

We know that ln ( a/b) = ln ( a) - ln (b)

ln (2e) - ln (x)

We also know that ln ( a*b) = ln a  + ln b

ln ( 2) + ln e  - ln x

We know that the ln e = 1

ln 2 + 1 - ln x

Changing the order

1 + ln 2 - ln x

Answer:

a(n) = 12 + 8n

a1 = 20

a4 = 44 = 20 + 8.3

.......

=> this is a arithmetic with a1 = 20

f(x) = 4 - x

Step-by-step explanation:

'f(x) = blah-blah' is the same as saying 'y = blah-blah', except it is also telling you that the x-y relationship is a function.

I notice that for each case, x + y = 4, so    y = 4 - x

Or in 'function' terminology,                       f(x) = 4 - x
