Answer: The domain is 3/7, -6, and 4.
Step-by-step explanation:
In the case of rational expressions, we can input any value except for those that make the denominator equal to 0 (since division by 0 is undefined). In other words, the domain of a rational expression includes all real numbers except for those that make its denominator zero.
Darnell is building a triangular community garden plot.
Which set of lengths can be used to create the plot perimeter?
Recall the triangle inequality theorem which states that the sum of any two sides must be greater than the third side.
Let us analyze each of the given options.
Option A:
a = 20 feet
b = 12 feet
c = 34 feet
Option B:
a = 8 feet
b = 10 feet
c = 19 feet
Option C:
a = 5 feet
b = 8 feet
c = 14 feet
Option D:
a = 12, feet
b = 14 feet
c = 20 feet
As you can see, only option D satisfies the triangle inequality theorem
Therefore, option D is the correct answer.
Answer:
see the explanation
Step-by-step explanation:
Let
x ----> the number of hours Eli worked
y ----> the number of hours Samantha worked
we know that
Eli and they ironed 400 shirts between them
so
----> equation A
Samantha worked 2 more hours than Eli
so
----> equation B
solve the system by substitution
substitute equation B in equation A
solve for x
Find the value of y
substitute the value of x in equation B
therefore
The number of hours Eli worked was 6 and the number of hours Samantha worked was 8
Answer:
c
Step-by-step explanation:
