Answer:
Step-by-step explanation:
let x be the length of third side.
10-5<x<10+5
or 5<x<15
so third side is between 5 and 15 .
Answer:
25%
because 4 goes into 16 4 times so kinda like a dollar if 16 was your dollar and you only got 4 it would be 25%
16 = $1
4 = 25 cents
A)find mode:2,4,6,8,6,4,2,4,2,4,6,6,4<br>B)If A= {0,1,2,3,4} find n(A)

The answer for the question Mode and number of A is
2/2, 4/4, 5/5, 7/7, or any fraction with the same numerator and denominator will be equivalent. All fractions equal 1.
Answer:
The equation can define y as a function of x and it also can define x as a function of y.
Step-by-step explanation:
A relation is a function if and only if each value in the domain is mapped into only one value in the range.
So, if we have:
f(x₀) = A
and, for the same input x₀:
f(x₀) = B
Then this is not a function, because it is mapping the element x₀ into two different outputs.
Now we want to see it:
x + y = 27
defines y as a function of x.
if we isolate y, we get:
y = f(x) = 27 - x
Now, this is a linear equation, so for each value of x we will find an unique correspondent value of y, so yes, this is a function.
Now we also want to check if:
x + y = 27
defines x as a function of y.
So now we need to isolate x to get:
x = f(y) = 27 - y
Again, this is a linear equation, there are no values of y such that f(y) has two different values. Then this is a function.
