Answer:
'-5'
Step-by-step explanation:
The table is a linear function. This means that all the points have a consistent slope. If two points had a different slope, it would be a nonlinear function.
Slope is rise over run. We are given the points (-3,0) and (-2,-5).

Given:
The graph of a system of equations.
To find:
The solution of the given system of equations.
Solution:
If a system of equations has two equations, then the intersection points of the graphs of these two equations are the solutions for the system of equations.
From the given graph it is clear that the graph of both line intersect each other at point
.
Therefore, the solution is
.
Answer:
-28
Step-by-step explanation:
Answer:
Step-by-step explanation:
- Speed of the boat = x
- Speed of the current = y
<u>Travel downstream, speed is:</u>
<u>Travel upstream, speed is:</u>
<u>Add up the equations:</u>
- x + y + x - y = 30 + 20
- 2x = 50
- x = 25
<u>Find y:</u>
Speed of the boat is 25 mph
Speed of the current is 5 mph
