Answer:
B (-2 , -11)
Step-by-step explanation:
hello : the system is :
y = 4x - 3
y= -x - 13
put x = -2
y = 4(-2) - 3=- 11
y= -(-2) - 13 = -11
Answer:
[-4,0) ∪ [2, ∞)
Step-by-step explanation:
For piecewise function domain and range, we need to understand the difference between "(" and "[" or ")" and "]"
- The parenthesis ( "(" and ")" ) are used for "open circles" in the graph.
- The brackets ( "[" and "]" ) are use for "closed circles" in the graph.
Range is the set of y-values for which the function is defined.
Now,
The upper part of the function shows the graph going from y = 2 towards infinity (arrow). At y = 2 , there is closed circle, so this part range would be
[2, ∞) (infinity is always with parenthesis)
Now, looking at bottom part, the function is defined from 0 (open circle) to -4 (closed). so we can write:
[-4,0)
This is the range, 2nd answer choice is correct.
[-4,0) ∪ [2, ∞)
I think you mean,
You can use the usual formula,
That in this case is,
Where I have used,
Answer:
E looks like it is most congruent

Answer:
Step-by-step explanation:
2y+3=5x-18
2y+21 = 5x
x = ⅖y + 21/5
