I NEED A HELP !!!!! how can i find the domain of the graph that i attached??!?!?
1 answer:
The correct answer is: {x ∈ R : x ≥ 2}
Explanation:
<span>Domain is the set of values of the independent variables for which a function or relation is </span>defined. In this question, any value of x less than 2 will have an imaginary outcome; therefore, they are not included in the domain of the given function g(x) =
Hence the domain will be any value of x greater than or equal to 2, where x is a real value. It is denoted by {x ∈ R : x ≥ 2}.

Answer:
Step-by-step explanation:
Speed of the bee = 15 miles per hour.
Formula to represent the speed of the bee will be,
Speed =
Distance = Speed × Time
Therefore, function representing the distance will be,
F(t) = s × t
Where t = time
s = speed
A). F(t) = 15t
B). If t = 20 minutes ≈ hours
F(t) = 15t
F(20) = = 5 miles
C). If f(t) = 12 miles
F(t) = 15t
By substituting these values in the function,
12 = 15t
t = = 0.8 hours ≈ 48 minutes
If this is your equation: 
Solution:
LCD for 5 and 5x is 5x
←cross product
20x + 30 = 5x² + 25x ←simplify with distributive property
0 = 5x² + 5x - 30 ←use inverse operations to collect all terms on one side
0 = x² + x - 6 ←if possible divide by numerical GCF (This case 5)
0 = (x + 3)(x - 2) ←Factor
x = -3 or x = 2
Please check by substitution in original equation... Both work

Answer:
The dimensions of the screen are
Length:102 feet
Width: 82 feet
Step-by-step explanation:
we know that
The area of the rectangle (movie screen) is equal to
where
L is the length
W is the width
we have
so
----> equation A
The screen is 20 feet longer than it is wide.
so
---> equation B
substitute equation B in equation A
solve for W
solve the quadratic equation by graphing
the solution is W=82 ft
see the attached figure
Find the value of L
therefore
The dimensions of the screen are
Length:102 feet
Width: 82 feet
