Multiply x^2-8x+15/3x * 8x/x-3

Mathematics
1 answer:
sergejj [24]3 years ago

You must follow the steps below:

 1. First, you should apply the dstributive property:

 =(x²-<span>8x+15/3x)(8x/x-3)
 =(8</span>x³-64x²+120x)/3x(x-3)

 2. As you can see, the common factor in the numerator is: "8x". So, you have:

 =8x(x²-8x+15)/3x(x-3)

 3. Then, when you simplify, you obtain:

 =8(x²-8x+15)/3(x-3)

 Therefore, the solution is: 8(x²-8x+15)/3(x-3)

How to solve an expression with variables in the exponents?
gtnhenbr [62]

Answer:

  use logarithms

Step-by-step explanation:

Taking the logarithm of an expression with a variable in the exponent makes the exponent become a coefficient of the logarithm of the base.

__

You will note that this approach works well enough for ...

  a^(x+3) = b^(x-6) . . . . . . . . . . . variables in the exponents

  (x+3)log(a) = (x-6)log(b) . . . . . a linear equation after taking logs

but doesn't do anything to help you solve ...

  x +3 = b^(x -6)

There is no algebraic way to solve equations that are a mix of polynomial and exponential functions.

__

Some functions have been defined to help in certain situations. For example, the "product log" function (or its inverse) can be used to solve a certain class of equations with variables in the exponent. However, these functions and their use are not normally studied in algebra courses.

In any event, I find a graphing calculator to be an extremely useful tool for solving exponential equations.

Here is a diagram and its corresponding equation. Find the solution to the equation.
fomenos

Answer:

The solution to the equation is:

  • <u>x = 2.5</u> or <u>x = 5/2</u>

Step-by-step explanation:

To find the solution to the equation, you only must operate the equation until you clear the x variable, with the next steps:

  • Equation: 4(x+7) = 38

And we solve:

  • 4x + 28 = 38 (we multiply 4 by x and 7)
  • 4x = 38 - 28 (we pass the +28 to subtract to the right side of the equality and operate)
  • x = 10 / 4 (we pass the 4 that is multiplying to divide to the right side of the equality)
  • <u>x = 2.5</u> (we divide)

As you can see, <u><em>the solution of the equation is </em></u><u><em>x = 2.5</em></u><u><em> or </em></u><u><em>x = 5/2</em></u>

Identify the GCF for he given set 23 and 115 A. 1 B. 23 C. 11
s344n2d4d5 [400]

Answer:

b. 23

Step-by-step explanation:

Using factor trees

23                              115

∧                                 ∧

1  23                           5  23

So,

23= 23

115= 23

If you circle the common factors in each factor tree, you get 23.

Therefore your answer is B
