The equation y = 3.5x represents the rate, in miles
avanturin [10]

Answer:

Piyush walks faster than Laura

Step-by-step explanation:

we know that

The rate or speed is equal to the slope of the linear equation

<em>Laura</em>

y=3.5x

The slope is 3.5\ \frac{mi}{h}

<em>Piyush</em>

Determine the slope of the line

we have the points

(0,0) and (4,18)

The line represent a direct variation (because passes through the origin)

so

m=\frac{y}{x}

For x=4 h, y=18 mi

substitute

m=\frac{18}{4}=4.5\ \frac{mi}{h}

Compare the slopes

4.5\ \frac{mi}{h} > 3.5\ \frac{mi}{h}

therefore

Piyush walks faster than Laura

Please help! The question is in the image
Goshia [24]

Answer:

I am pretty sure that your answer would be 3.

Step-by-step explanation:

The reason why is because if B if half of line segment AD and AD is equal to 12, then B must be equal to 6 since half of 12 is 6. Next, since C is the mid-point for line segment BD then C must be 3 since half of 6 is 3. And finally, that means line segment BC is three since it is 1/2 of BD.

Hope this helps! :)
