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

The price of a man's shirt went from $15 to $20. What was the percent of increase of the price of the shirt? A. 25% A. , 25%, B.
dexar [7]

Answer: 33 1/3%

Step-by-step explanation:

Percentage increase of the shirt will be calculated as:

= Price Increase / Old price × 100%

Price Increase = $20 - $15 = $5

Old price = $15

Percent increase = Price Increase / Old price × 100%

= 5/15 × 100

= 1/3 × 100

= 33 1/3%

Solve for x please for 10 points
Ira Lisetskai [31]

Answer:

\frac{x-2}{2+1}=\frac{4x-5}{3}

\frac{x-2}{3} =\frac{4x-5}{3}

3*\frac{x-2}{3} =\frac{4x-5}{3}*3

x-2=4x-5

x-2+5=4x-5+5

x-x+3=4x-x

3=3x

\frac{3}{3} =\frac{3x}{3}

1=x

Step-by-step explanation:

What is the slope of these two equations?
Juli2301 [7.4K]

Answer:

8. 0

9. undefined

Step-by-step explanation:

8. 0

> because the y variable is the same for all x-values, this is a horizontal line. Horizontal lines have a slope of 0.

  > <em>Thinking of slope as rise over run: we will always rise 0, and run __ from any two points--0 divided by any number is always 0</em>

9. undefined

> because the x variable is always the same, no matter what y variable we graph, we will have the same outcome. So, this would look like a straight line, which have an undefined slope.

   > <em>If you think of a slope as rise / run; if you go from any two points, there will be a 0 in the denominator--which is undefined</em>

<em />

<em />

hope this helps!! have a lovely day :)
