Answer: Cyndy: speed = 4mph;

Taylin:\frac{distance}{time} = \frac{4}{\frac{1}{2} }, speed = 8mph;

Judy: \frac{distance}{time} = \frac{5\frac{1}{4} }{\frac{3}{4} }, speed=7 mph;

Step-by-step explanation: To complete the table, it has to be written the distance / time and the speed (unit rate) of each girl.

<u>Cyndy</u>:

For her, the first column is already given:

\frac{distance}{time} = \frac{6}{1\frac{1}{2} }

Speed is the distance traveled divided by how much time it was needed to walk the distance:

speed = \frac{6}{\frac{3}{2} }

speed = 6.\frac{2}{3}

speed = 4 miles per hour (mph)

<u>Taylin:</u>

<u />\frac{distance}{time} = \frac{4}{\frac{1}{2} }<u />

speed = 4.2

speed = 8mph

<u>Judy:</u>

<u />\frac{distance}{time} = \frac{5\frac{1}{4} }{\frac{3}{4} }<u />

speed = \frac{5\frac{1}{4} }{\frac{3}{4} }

speed = \frac{\frac{21}{4} }{\frac{3}{4} }

speed = \frac{21}{4} . \frac{4}{3}

speed = 7mph

Determine whether the system of linear equations has one solution infinitely many solutions or no solution explain your reasonin
hammer [34]

Answer: The equations have no solution because no solution graphs have the same slopes but difference y- intercepts.And by looking at the equations they both have same slope as 3 but different y-intercepts 5 and -5.

Step-by-step explanation:

y= 3x + 5

y = 3x- 5

3x + 5 = 3x -5

-3x          -3x

       5 ≠ 5

What are the zeros of 3x²(x+π)³(x-4)²
Aneli [31]
Hi again!

The zeros are the values of x. This is where the graph intersects the x - axis. In order to find the zeros, replace y with 0 and solve for x.

The answer is x = 0, -π, 4

I am not sure what grade are you or the level, but for me, they sometimes asked me to find their multiplicities as well

The multiplicity of a root is the number of times the root appears.

So, the answer are
x = 0 and the multiplicity of 2
x = -π and the multiplicity of 3
x = 4 and the multiplicity of 2

Good luck with your studies!
