Answer:
Function
Step-by-step explanation:
The reason it is a function is because its saying y=x. Then you just plug in the number(s) to get the function y=4.PLEASE MARK BRAINLIEST thank you!!!!!!!!!
Answer:
D
Step-by-step explanation:
We will use the 2 coordinates marked on the graph as the reference.
The coordinates are:
A(4,-2)
B(0,3)
We know that the standard form for equation of line is:
y = mx+c
where m is the slope of the equation
and c is the y-intercept.
Very clearly, the y-intercept is where the line intercepts the y line.
and in this case, y-intercept = c = 3.
Now we know that the equation of line is now
y = mx + 3
To find m, the slope, we can use the 2 above coordinates.
slope of line = 
(Note: There is a 2nd way to find the slope in this case, let me know if you are interested to find out.)
Equation of line: 
Therefore the answer is D.
Answer:
9/11
Step-by-step explanation:
Well we know there are 55 students in total and only 45 of them can either play a string or brass instrument.
So 45/55 is 9/11
Thus probably is 9/11 of a randomly selected student who plays either a string or brass.
1st. x times 20+100
2nd. 100+20x
3rd. 100+x times20
4th. 20x+100
5th. x20+100
