Answer:
-1 = -4
0 = -3
-5 = -8
-2 = -5
Step-by-step explanation:
What you are doing is adding -3 to each number. An equation will look like:
x+-3=y. You will then take the x and plug it into the x and you will find the y.
-1+-3=-4.
You will do this for each one.
Answer:
19.9 i think
Step-by-step explanation:
125/3.14=39.8
39.8/2=19.9
hope i helped
Answer:
see explanation
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y) → (x, - y), hence
A(- 6, 2) → A'(- 6, - 2)
B(- 9, 1) → B'(- 9, - 1)
C(1, - 6) → C'(1, 6)
To solve this problem you must apply the proccedure shown below:
1. By definition, the rate of change of a linear function is the slope of the line and it is constant. Based on this, you must find the slope of the given function.
2. You have the equation of the line has the following form:
Where 
is the slope and 
is the y-intercept.
3. Then, you have that the slope of the function 
is:
Therefore, the answer is: 
Answer:
Eastbound train: 95 miles per hour
Westbound train: 105 miles per hour
Step-by-step explanation:
Let:
- e = speed of the eastbound train
- w = speed of the westbound train
The eastbound train travels 10 miles per hour slower than the westbound train
So e = w - 10
Every hour, the distance between the two trains is the sum of the values.
(w - 10) + w = distance apart in 1 hour
5(w - 10 + w) = distance after 5 hours
Solve:
- 5(w - 10 + w) = 1000
- 5(2w - 10) = 1000
- 10w - 50 = 1000
- 10w = 1050
- w = 105
The westbound train is 105 miles/ hour.
The eastbound train is 95 miles per hour
