<span>1/(x+a) - 1/(x+b) = 1/a x 1/b

First, rewrite this as    </span><span>1/(x+a) - 1/(x+b) = (1/a)(1/b)  (do not use "x" to indicate                                                                                       mult.)

Then the LCD is (x+a)(x+b)(ab)

so the first term becomes (x+b)(ab), and
the second becomes (x+a)(ab), and 
the third becomes (x+a)(x+b).

Thus, we now have   (x+b)(ab) - (x+a)(ab) = (x+a)(x+b)(b) + (x+a)(x+b)(a).

Now, with the fractions gone, can you solve thios for x?</span>

Largest Possible GCF (Greatest Common Factor)
Ipatiy [6.2K]

Answer:

<h2>96 and 48</h2>

Step-by-step explanation:

To solve this problem we have to find the largest possible greatest common factor, which is 48.

Now, numbers 96 and 48 have as Greatest Common Factor 48, that's the largest number possible that is common to both numbers because

48/48 = 1

96/48 = 2

Therefore, the answer is 96 and 48, because they don't have repetitive digits.

Answer: C

Step-by-step explanation:

We are given the information that:

  1. The airplane is at 50,000 feet
  2. It descends 2,500 feet in 1 minute
  3. x = minutes

For  ease of solving this question, let's set the number of minutes (x) to 1.

  • In one minute, we know the plane will drop to 47,500 feet. (50,000 - 2,500(x))

There are multiple ways to write this equation bu shifting around negative and positive values. Another way to write this equation would be (-2,500(x) + 50,000). That would be choice C.

Try it out~

(-2,500(x) + 50,000)\\ (-2,500(1) + 50,000)\\ (-2,500 + 50,000)\\47,500

It works, so our answer is C.

Observe the graph below. The scale factor used to dilate ABC was...
Lera25 [3.4K]

Answer:

3

Step-by-step explanation:

AB = 1 unit

A'B' = 3 units

The scale of dilation = A'B'/AB

Therefore:

scale of dilation = 3 units / 1 unit = 3

This means that ABC was dilated or enlarged in size by multiplying every of its segment by 3. In essence, A'B'C' is 3 times the size of ABC.
