Answer:
From the information given
x is time for which she ran at speed of 6mi/h and
y is time for which she biked at speed of 12.5 mi/h
total time = 3.5 h
total distance = 34 mi
so
6x + 12.5y = 34 and
x + y = 3.5
x = 3.5 - y
6 ( 3.5 - y) + y = 34
6.5y = 13 which gives
y = 2 and this
x = 1.5
so suze ran for 1.5 h and biked for 2 h
CHECK
speed of run X time of run + speed of biking x time of biking must be = total distance covered
6 × 1.5 + 12.5 × 2 = 9 + 25= 34 mi
which is true
Answer:
(4,-3)
Step-by-step explanation:
It is discovered using its notion that the domain and range of the function are given by (C) D: [–4, ∞) and R: [0, ∞).
<h3>
What are the domain and range of a function?</h3>
- The domain of a function is the set of values that can be plugged into it. This set contains the x values in a function like f(x).
- A function's range is the set of values that the function can take.
- This is the set of values that the function returns after we enter an x value.
To find the domain and range:
- The given function in the problem is:

- Because the square root function does not exist for negative numbers, the domain is denoted by:
≥
→
≥ 
- Therefore, it is discovered using its notion that the domain and range of the function are given by (C) D: [–4, ∞) and R: [0, ∞).
- The range of the square root function is
≥
, which remains the same as there are no vertical translations.
Therefore, it is discovered using its notion that the domain and range of the function are given by (C) D: [–4, ∞) and R: [0, ∞).

Answer:
158 natural numbers
158 natural numbers from 78 to 234, and 699 whole numbers from 24 to 721. Step-by-step explanation: Natural numbers are positive integers (whole numbers), so all numbers from the range of 78 to 234 would be included, including 78 and 234 itself.
