Answer: 7/4
Step-by-step explanation: because you simplify
Answer:
16 and 4
Step-by-step explanation:
Let (x+y) =20 and (x-y)=12 then:
Isolate for x in each equation
x=20-y and x=12+y
Set the equations to equal each other since the value of x should be the same for both
20-y = 12+y
Rearrange so that y is on one side and the numbers are on the other
8 = 2y
y= 8/2
y= 4
Now substitute the y- value back into either of the original equations
x+y= 20
x+4 = 20
Rearrange and isolate x
x = 20-4
x = 16
So the two values are 16 and 4
I can eyeball points (1/2, 8), (1,4), (2,1), (3,1/4)
The pattern is each increment of 1/2 in x divides by two.
Any of the points give k=16
Check: x=1/2 4^(3/2)=2^2=8 good
x=1 4^(2-1)=4 good
x=2 4^(2-2)=1 good
x=3 4^(2-3)=1/4 good
speed = distance / time = 100 m / 50 s = 2 m/sec
Juan average speed is 2 m / sec
