(-1.5,3) Y=3 which is up 3 and a horizontal line and 2x+y=0 can be written as y=-2x so in order to get -1.5 you have to make y=3 cause y=3 and when you do that it should look like 3/-2=-2/-2x so x=-1.5
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)

Step-by-step explanation:
<span>3ab-9ab+7ab = ab
</span><span>A-
2(5x-3)=24
10x - 6 = 24
10x = 30
x = 3
</span><span>B-
5(2x+1)=50
</span>10x + 5 = 50
10x = 45
x = 4.5
