Answer:
C.
Step-by-step explanation:
Even if it is a piecewise function, we don't really need to approach it that way. Since both of the given equations have a slope, our only viable option is C because it is the only graph that shows the 2 slopes. All the other graphs show 1 slope and a 0 slope (horizontal line) so C. is our best choice.
Answer:
Step-by-step explanation:
The top and bottom segments have same length.
a)
- n + n + 19 = 33
- 2n + 19 = 33
- 2n = 33 - 19
- 2n = 14
- n = 14/2
- n = 7
b)
- x + x + x + 3 = 30
- 3x = 30 - 3
- 3x = 27
- x = 27/3
- x = 9
Answer:
Step-by-step explanation:
Looking at the graph
For x=-2 ---> f(x)=3
For x=2 ---> f(x)=1
so
we have the points
(-2,3) and (2,1)
Find the slope
The equation of the line in slope-intercept form is equal to
we have
---> see the graph
substitute
Answer:
She will needs to work at least 8 hours or more to have $260 a day.
Step-by-step explanation:
260 + 75 = 335
335 : 42 = 7.976
7.976 rounds up to 8 Hours
