Answer:
5
Step-by-step explanation:
f(4) falls into the category x > -1 because 4 > -1. Therefore, we use the function f(x) = 2x - 3. f(4) will then equal 2(4) - 3 = 5.
Answer:
5 and 61
Step-by-step explanation:
Using Pythagoras' identity in the right triangles
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
(1)
c² = a² + b² = 3² + 4² = 9 + 16 = 25 ( take the square root of both sides )
c =
= 5
(2)
c² = a² + b² = 11² + 60² = 121 + 3600 = 3721 ( take the square root of both sides)
c =
= 61
That would be a ray. A mathematical ray has an endpoint but continues forever in a direction, unlike a line which continues in both directions.

Step-by-step explanation:
Hope this helps it was super confusing and i didnt rlly understand it. pls let me know if itss wrong and i will edit my answer. If right, mark be brainlist!
The slope form is this y=mx+b
where "m" is the slope so;
m= 3/4
