Answer:

false statement

Step-by-step explanation:

5+x^2=2x^2+13

5+x^2-2x-13=0

-8+x^2-2x^2=0

-8-x^2=0

-x^2=8

x^2=-8

this statement is false for any value of x because the power function with an even exponent is always postive or 0

What is f(-3) if f(x) =|2x-1|-5
dangina [55]
F(x) = |2x-1|-5

f(x) = |2*(x)-1|-5

f(-3) = |2*(-3)-1|-5 ... replace every x with -3

f(-3) = |-6-1|-5

f(-3) = |-7|-5

f(-3) = 7-5

f(-3) = 2 which is the final answer

Side Note: the vertical bars mean "absolute value" which represents distance. Negative distance makes no sense which is why absolute value results are never negative.

spayn [35]

Answer:

The competition took 12.5 minutes.

Step-by-step explanation:

Let the time taken by Achilles to complete the competition is h hours.

Now, Achilles runs at a speed of 13 mph while the Turtle moves at a speed of 1 mph.

So, the competition was 13h miles long.

Now, Turtle will take h hours to complete h miles of the competition.

Now, given that (13h - h) = 2.5

⇒ 12h = 2.5

⇒ h = 0.208 hours.

⇒ h = 12.5 minutes.

Therefore, the competition took 12.5 minutes. (Answer)
