Answer:
-3
Step-by-step explanation:
-x^2 +x–1
Let x = -1
- (-1)^2 + (-1) -1
- 1 -1 -1
-3
Answer:
0
Step-by-step explanation:
the equation after plugging in "x" is
-(-1)*(2)+(-1)-1
then after multiplication it is
2-1-1
this becomes 0
Answer:
The number of hours each riders ride = 15 hours.
Step-by-step explanation:
19 riders = 11 days 21 hours to ride from St.Joseph to Sacramento
Let's find the number of hours taken.
1 day = 24 hours.
11 days = 11 times 24 = 264 hours
So, 11 days 21 hours = 264 + 21 = 285 hours
19 riders rode the same number of hours.
To find the each rider ride, we need to divide 285 by 19.
The number of hours each rider ride = hours.

Answer:
y = - 3
Step-by-step explanation:
Locate x = 2 on the x- axis, then go down vertically until the line is met.
Then read the corresponding y- coordinate at this point.
When x = 2 the value of the function is y = - 3
Answer:
-3
Step-by-step explanation:
We are given that a graph.
We have to find the value of the function at x=2.
To find the value of function at x=2 we will find the value of y corresponding to x=2 by drawing a vertical line x=2
The given graph is the graph of a line.
We can see that when we draw a vertical line x=2 and parallel to y- axis.
Then, the vertical line x=2 cut the given line at pint (2,-3).
Therefore, the intersection point of line x=2 and the given line is (2,-3).
The value of y corresponding to x=2 is -3.
We know that
Therefore, the value of the given function at x=2 is -3.
Hence, the value of the function at x=2 is -3.
