Answer:
x= -11/10
Step-by-step explanation:
-6.75 + 21/4 - 3.25 - -11/10= -3.65
The answer to this would be 1/3
Step-by-step explanation:
let v is the speed of the wind,
the equation of the speed:
(550 + v ) × 5 = (550 - v) × 6
2750 +5v = 3300 - 6v
11v = 3300 - 2750
11v = 550
v = 550/11
v = 50
therefore, the speed of the wind =
50 mph
Answer:
x=-3
Step-by-step explanation:
1-7x-7=15
We move all terms to the left:
1-7x-7-(15)=0
We add all the numbers together, and all the variables
-7x-21=0
We move all terms containing x to the left, all other terms to the right
-7x=21
x=21/-7
x=-3
The domain of the function where the function is decreasing is (-∞, 1). Then the correct option is D.
<h3>What are domain and range?</h3>
The domain means all the possible values of the x and the range means all the possible values of the y.
The function is given below.
f(x) = x² - 2x + 5
The equation can be written as
f(x) = x² - 2x + 1 + 4
f(x) = (x - 1)² + 4
Then the domain of the function where the function is decreasing will be (-∞, 1).
Then the correct option is D.
More about the domain and range link is given below.
