Brandon found that a solution of x = 1 was extraneous for his function. What would be a possible denominator in Brandon's function?2x + 4

x2 + 3x + 9

3x - 11

x2 + 3x - 4

Answers

Answer 1
Answer: An extraneous solution is obtained when the simplified version of the function drives to a value thas does not belong to the domain of the complete function.

So, if x = 1 is an extraneous solution, it does not belong to the original domain.

if when you replace x = 1 in the expression of the denominator it results in 0, then it is an extraneous solution, because you cannot accept it as a valid solution.

Then we must check which of the expressions listed in the options drive to that possibility.

The promising choice is x^2 + 3x - 4.

Inded,  If you substitute x = 1, you get (1)2 + 3(1) - 4 = 1 + 3 - 4 = 4 - 4 = 0.

And the answer is x^2 + 3x - 4.

Rounding up this number of people to nearest ten thousand.

9 has a 'ones' value

Going to the right from left:

Second last zero has a 'tens' value.

Third from last zero has a 'thousands' value

4 has 'ten thousands' value

Round up 4 and because it is less than five it converts to zero

This gives an answer of  830,000.

10 over 7 x 3 over 8

Answers

When you multiple fractions, you just multiple numerators and denominators.

10 / 7 × 3 / 8 = (10 × 3) / (7×8) = 30 / 56

Now reduce the fraction:

30 / 56 = 15/28

Final answer: 15/28

Canada Olympic Park features sports training and entertainment facilities.The monster Zip line produces average speed of 120 kilometers per hour. A smaller line produces speeds represented by the function d=50h where d is the distance in kilometers after h hours. How much farther could you travel on the Monster Zip line in 0.25 hoursThe answers I can choose are

18km

16km

20km

17.5km

​

Answers

Answer:

17.5 Km

Step-by-step explanation:

In Monstor zip line, it's 120 km /hour

so in 0.25 hours, it's 0.25 * 120 = 30 Km

in another small

d = 50*h

= 50*0.25

= 12.5 km

so you travel (30-12.5)km farther on the monster zip line = 17.5 Km
