7x - 4 / (x-8)(x+5) = a/x-8 + 3/x+5

Find for a

Step-by-step explanation:

You divide each term by -2

Answer:

slope -intercept form

y = -328.275 x + 3142.15

Step-by-step explanation:

Step(i):-

Given that the points are (2, 2485.6) and (6,1172.5)

The slope of the line

               [tex]m = \frac{y_{2}- y_{1} }{x_{2}-x_{1} }[/tex]

              [tex]m = \frac{1172.5-2485.6 }{6-2 }[/tex]

            [tex]m = - 328.275[/tex]

Step(ii):-

Equation of the straight line passing through the Point (2,2485.6)

[tex]y - y_{1} = m(x-x_{1} )[/tex]

y - 2485.6 = (-328.275)(x-2)

y - 2485.6 = -328.275x+656.55

  y =  -328.275x+656.55 + 2485.6

y = -328.275 x + 3142.15

Final answer:-

slope -intercept form

y = -328.275 x + 3142.15

Answer:

-3=-8, -2=-4, 1=8, 3=16, 4=20

Step-by-step explanation:

Answer:

5, 12, 19, 26, 33

Step-by-step explanation:

This is an arithmetic sequence since there is a common difference between each term. In this case, adding 7 to the previous term in the sequence gives the next term. In other words, an=a1 + d(n − 1) .

Arithmetic Sequence:  d=7

This is the formula of an arithmetic sequence.an=a1 + d(n-1)

Substitute in the values of

a1=5 and d=7. an=5 + (7) (n − 1)

Simplifly each term : an=5 + 7n − 7

Subtract  7  from 5.

an=7n − 2

Answer:

D. [tex]\sqrt{65}[/tex]

Step-by-step explanation:

The computation of the  length of a diagonal (AC or BD) of the rectangle is shown below:

As we know that

The Diagonal length of AC is

[tex]= (x_2 - x_1)^2 + (y_2 - y_1)^2\\\\= (9 -2)^2 + (8 - 4)^2\\\\= (7)^2 + (4)^2[/tex]

[tex]= \sqrt{49 + 16}\\\\= \sqrt{65}[/tex]

Therefore correct option is D.

Answer:

[tex]1\dfrac{3}{32}\ \text{inches}^2[/tex]

[tex]4\dfrac{1}{4}\ \text{inches}[/tex]

Step-by-step explanation:

w = Width of a stamp = [tex]\dfrac{7}{8}\ \text{inch}[/tex]

l = Length of a stamp = [tex]1\dfrac{1}{4}\ \text{inch}[/tex]

Area is given by

[tex]A=lw\\\Rightarrow A=\dfrac{7}{8}\times 1\dfrac{1}{4}\\\Rightarrow A=\dfrac{7}{8}\times \dfrac{5}{4}\\\Rightarrow A=\dfrac{35}{32}\\\Rightarrow A=1\dfrac{3}{32}\ \text{inches}^2[/tex]

The area of each stamp is [tex]1\dfrac{3}{32}\ \text{inches}^2[/tex]

Perimeter is given by

[tex]P=2(l+w)\\\Rightarrow P=2(\dfrac{7}{8}+\dfrac{5}{4})\\\Rightarrow P=2\times \dfrac{17}{8}\\\Rightarrow P=\dfrac{17}{4}=4\dfrac{1}{4}\ \text{inches}[/tex]

The perimeter of each stamp is [tex]4\dfrac{1}{4}\ \text{inches}[/tex].

Answer:

254.34 cm²

Step-by-step explanation:

A = πr2 Use the formula.

A = π(9)2 Substitute. Use 9 for r.

A ≈ 3.14 × 92 Substitute. Use 3.14 for π.

A ≈ 3.14 × 81 Evaluate the power.

A ≈ 254.34 Multiply.

The area of the DVD is about 254.34 cm².

There are 3 kilograms weight must be removed from the first case and placed in the second is that they both equal.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Fruit weight = 53 kilograms

And, Another weight = 47 kilograms

Now,

Let number of kilograms weights to remove and add = x

So, We can formulate;

⇒ 53 - x = 47 + x

Solve for x as;

⇒ 53 - 47 = x + x

⇒ 6 = 2x

⇒ 2x = 6

⇒ x = 3

Thus, There are 3 kilograms weight must be removed from the first case and placed in the second is that they both equal.

Answer:

it has no pic

Step-by-step explanation:

The expression that can be factored into the form (ax + b)(ax - b), where a and b are rational numbers, is 4n² - 81.

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

Here,

A.
4n² - 81,
This can be factored as (2n - 9)(2n + 9), which is of the form (ax + b)(ax - b).

B.

2n² - 49,
This can be factored as (n - 7√2)(n + 7√2), but not in the form (ax + b)(ax - b).

C.

2n² + 49:

This cannot be factored into the form (ax + b)(ax - b) using rational numbers. We can factor it over the complex numbers as (n + i√49/2)(n - i√49/2), where i is the imaginary unit, but this does not satisfy the conditions of the problem.

D.

4n² + 81,
This cannot be factored into the form (ax + b)(ax - b)

Therefore, the expression that can be factored into the form (ax + b)(ax - b), where a and b are rational numbers, is 4n2 + 81.

Step-by-step explanation:

Function A rate of change:

Using two given pairs of values, (4, 32) and (8, 44):

Rate of change = ∆y/∆x

= (44 - 32)/(8 - 4)

= 10/4

Rate of change = ⁵/2
