Answer:
a) 1st and 2nd
b) 4th one
Step-by-step explanation:
Since you're looking for the unit rate, you can start do this:
And yes,
is also correct, it's just switching around the 15
Answer:
The third one
Step-by-step explanation:
Answer:
Their slopes and y-intercepts are the same
Step-by-step explanation:
For example:
y=3x+5
y=3x+5
3x+5=3x+5
3x=3x
x=x
Thus, there's infinitely many solutions
Answer:
Graph A → y=√x.
Graph B → y=(√x) - 1.
Graph C → y=√(x-1).
Graph D → y= -√x.
Graph E → y= -√(x-1)
Step-by-step explanation:
The graph 'A' intercepts the y-axis at (0, 0). Therefore it belongs to the function y=√x.
The graph 'D' is exactly the same graph 'A' but reflected across the x-axis. Therefore, it belongs to the function y=-√x.
The function 'C' is exactly the same function y=√x but translated one unit to the right, therefore, the solution function is y=√(x-1)
The graph 'E' is exactly the same graph 'C' but reflected across the x-axis, therefore the function is: y= -√(x-1)
In the options you have two times the function y=√x. I assume that's a mistake. The graph 'B' corresponds to y = (√x) - 1
