Answer: 28.9%

Step-by-step explanation:

Calculate percentage change

from V1 = 89 to V2 = 64

(V2−V1)|V1|×100

=(64−89)|89|×100

=−2589×100

=−0.280899×100

=−28.0899%change

=28.0899%decrease

or about 28.9%

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
