Answer:
The temperature of the oven after 6 minutes is 125 degrees and after 10 minutes its 165 degrees.
Step-by-step explanation:
10 x 6 = 60
60+65=125
10 x 10 = 100
100+65=165
Answer:
The constant of proportionality (k) is 1/5.
Step-by-step explanation:
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
Hope this helps and I hope u have an Amazing day!!
Answer:
I prefer to express solutions to inequalities using interval notation. Both formats are are important but I think interval notation is easier to understand and represents better the solutions.
For example, if you have the following inequation:
x-2> 1
x>3
Therefore, the solution could be written either x>3 OR (3, +inf). But what happens if the solution to the system of equation is x>3 or x<-3? The solution can be easily written as: (-inf, -3) U (3, inf) instead of <em>'x>3 or x<-3' </em>which is more confusing.
Answer:
The second one is not true the left side 3 does not equal the left side 7, which means it is not true.
The third one is also not true because the left side 9 does not equal the left side 3, which also means it is not a true statement

Answer:
(3, 4)
Step-by-step explanation:
A function is a relation that maps elements from a set (the domain, the set of the inputs) into elements from another set (the range, the set of the outputs).
Such that a function can map each element of the domain into only one element of the range.
Then, if a "function" has:
f(x1) = y1
and
f(x1) = y2
It is mapping the input "x1" into two different outputs, then this is not a function.
Now, we know that the ordered pair (3, -4) is among the points on the graph of the function f(x)
(The first value is the input and the second one is the output)
Then the point that does not belong to the graph, is the point that has the same input and different output.
(3, 4)
Any of the other points could belong to the graph.
