The answer to ur problem is 15 x
Answer:A system of linear equations usually has a single solution, but sometimes it can have no solution, or infinite solutions.One solution. A system of linear equations has one solution when the graphs intersect at a point.
Step-by-step explanation:
The first thing we must do in this case is to define variables.
We have then:
x: speed of the giraffe
x + 5: speed of the ostrich
By definition we have:
d = v · t
d / v = t
Where,
d: distance
v: speed
t: time
Since the time is the same then we have:
5 / (x + 5) = 4 / x
5x = 4 (x + 5)
Clearing x we have:
5x-4x = 20
x = 20 mph (speed of the giraffe)
x + 5 = 20 + 5 = 25 mph (speed of the ostrich)
Answer:
20 mph (speed of the giraffe)
25 mph (speed of the ostrich)
Answer:
Use a graphing calc.
Step-by-step explanation:
On the graph, use (0, 0) and (2, 5) to graph the function.
