Answer:
see below
Step-by-step explanation:
There are two points where y = -3
at x = -2 and x = 1
when x = 0 f(0) = 1
Answer:
x=107
Step-by-step explanation:
180-73=107
2/3 miles in 1/12 of a hour
We need twelve 1/12 to make a whole hour
(2/3)•12 = 24/3= 8 miles
8 miles per hour
3 types
There are three types of systems of linear equations in two variables, and three types of solutions. An independent system has exactly one solution pair (x,y) . The point where the two lines intersect is the only solution. An inconsistent system has no solution.
Answer:
The chart goes as follows.
| wearing a watch | no watch | total
