Write a sentence explaining why all solutions of rational equation must be checked

Mathematics
1 answer:
algol [13]3 years ago
4 0

Answer:

  Some found solutions may be extraneous, so they must all be checked in the original equation.

Step-by-step explanation:

All "solution" values that make any denominator of a rational expression zero must be excluded from the solution set. Every solution must be checked to make certain it is not excluded.

Please help asap pleaseeee (picture shown)
Paraphin [41]

The correct answer is 3x+90=180

<em>Because you add the 2x and the x and you get 3x then there is a 90 degree angles so you add that and =180</em>

<em>Once you put it in the equation you can subtract 90 from 180 and you get 90 which you then divided by 3x and x equals 30</em>

URGENT ! what is the common difference of the arithmetic series 14+12+10+8
k0ka [10]

Explanation:

An arithmetic sequence has a common difference, meaning you use addition or subtraction to get from term to term, and each term in the sequence is an equal distance apart.

A geometric sequence has a common ratio, meaning that you use multiplication or division to get from term to term.

If you look at this sequence:

14-2 = 12

12-2 = 10

10-2 = 8

8 -2 = 4

etc.

Because you are subtracting 2 each time, 2 is the common difference, and the sequence is arithmetic.

lukranit [14]

Answer:

Difference = 283.2\ miles/hour

Step-by-step explanation:

Given

Average\ Speed = 34.8\ miles/hour

Highest\ Speed = 318.0\ miles/hour

Required

Determine the difference in the highest speed and the average speed

Difference = Highest\ Speed - Average\ Speed

Difference = 318.0\ miles/hour - 34.8\ miles/hour

Difference = 283.2\ miles/hour

<em>Hence, the highest speed is 283.2 miles/hour faster than the average speed</em>
