Answer: Option A
Step-by-step explanation:
In the graph we have a piecewise function composed of a parabola and a line.
The parabola has the vertex in the point (0, 2) and cuts the y-axis in y = 2.
The equation of this parabola is
Then we have an equation line
Note that the interval in which the parabola is defined is from -∞ to x = 1. Note that the parabola does not include the point x = 1 because it is marked with an empty circle " о ."
(this is )
Then the equation of the line goes from x = 1 to ∞ . In this case, the line includes x = 1 because the point at the end of the line is represented by a full circle
.
(this is )
Then the function is:
Answer:

Step-by-step explanation:
Working at the same rate for 8 weeks means you would either have to add 135 eight times, or do 135 x 8.
Answer:
t 24
Step-by-step explanation:
we can add 5 to both sides
-t/6 -4
multiply both sides by 6
-t -24
divide by -1, when dividing by a negative, the inequality flips
t 24
