For the first question, x = 4
Answer:
(- 19, - 11, 5, 25)
Step-by-step explanation:
The given function is f(x) = 4x - 7
Now, we have to find the range of the given function for the given domains.
The domains are given as (2 - 5, - 1, 3, 8) i.e. (- 3, - 1, 3, 8).
Therefore, f(- 3) = 4(- 3) - 7 = - 19
f(- 1) = 4(- 1) - 7 = - 11
f(3) = 4(3) - 7 = 5
f(8) = 4(8) - 7 = 25
So, the ranges of the function are (- 19, - 11, 5, 25) (Answer)
Answer:
45-40
Step-by-step explanation:
The first interval is 15-19.
The width of this interval is: 19-15=4
The second interval is 30-34.
The width of this interval is: 34-30=4
The third interval is 40-45.
The width of this interval is: 45-40=5
The fourth interval is 45-49.
The width of this interval is: 49-45=4
<h3>Therefore the interval that is not equal to the other three is 45-40</h3>
Answer:
10
Step-by-step explanation:
let the number be n then half the number is
n , so
n + 69 = 74 ( subtract 69 from both sides )
n = 5 ( multiply both sides by 2 to clear the fraction )
n = 10
Thus the number is 10
6 divided by 3.79 = 1.583 gallons
