Answer:
No
Step-by-step explanation:
Using the given values, 25 is the largest value, so if this were a right triangle, it would be the hypotenuse.
Using Pythagoras' theorem: For this triangle to be a right triangle, √(21² + 14²) must be equal to 25.
√(21² + 14²) = 25.239 (5sf) ≠ 25
Hence the triangle formed is not right.
It would take you 15 minutes. Since one hour equals 60 minutes your equation would look like this:
4x=60
So you need divide 4 into both sides in order to find the value of x which represents one mile.
So one mile takes 15 minutes to walk or x=15.
Answer:
For functions, the two notations mean the exact same thing, but "f (x)" gives you more flexibility and more information. You used to say "y = 2x + 3; solve for y when x = –1". Now you say "f (x) = 2x + 3; find f (–1)" (pronounced as "f-of-x equals 2x plus three; find f-of-negative-one").
