Answer: x > 3
Step-by-step explanation:
We have the inequality:
-4*(2*x - 7) < 10 - 2*x
We want to find the possible values for x.
first, we expand the left side.
-8x + 28 < 10 - 2x
now we want to have all the terms with x in one side and the terms without x in the other side.
-8x + 2x < 10 - 28
-6x < -18
now we divide both sides by -6, as we divide by a negative number, the direction of the inequality changes:
x > 18/6 = 3
x > 3
This means that x must be larger than 3.
ANSWER
All real numbers greater or equal to -3.
EXPLANATION
The domain of the given function are values of x that make the function defined.
We can see from the graph that, the domain are x-values greater than or equal to -3.
In other words, we can find a corresponding y-value for all x-values greater than or equal to -3.
The correct answer is option D.
First, change each mixed fraction into improper
2 3/8 = 19/8
1 3/4 = 7/4
The problem will look like: (19/8)/(7/4)
To solve, flip the second fraction, and change the division sign into a multiplication sign.
(19/8)/(7/4) = (19/8) x (4/7)
Multiply across
(19/8) x (4/7) = 76/56
Simplify.
76/56 simplified = 19/14
Change to mixed fraction
19/14 = 14/14 + 5/14 = 1 5/14
1 5/14 is your answer
hope this helps

Answer:
Yes it is a function
Step-by-step explanation:
We have to check the ordered pairs to find out if given relation is a function or not.
In an ordered pair, the first element represents the input and the second element represents the output.
The set of inputs is domain and output is range.
For a relation to be function, there should be no repetition in domain i.e there should be unique pairs of input and output.
In the given relation, the domain is {3,5,-1,-2}.
No element is repeated hence it is a function ..
