The values in the table below represent Function B, which is a linear function.
yan [13]
<h3>1. Compare Functions B and L by determining which one has the greater rate of change.</h3>

The rate of change is expressed as the ratio between a change in one variable relative to a corresponding change in another. On the other hand, a linear function is given as the form:

y=mx+b

And m is the rate of change we are looking for. For Function B we have a Table and the slope can be found by choosing two points, therefore:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ Choosing \ (1,5) \ and \ (3,11) \\ \\ m=\frac{11-5}{3-1}=3

As you can see y=6x+4 has a rate of change of 6 while the function of the table has a rate of change of 3.

<em> In conclusion,</em> y=6x+4 <em>has the greater rate of change</em>

<h3>2. which one has a greater y-intercept?</h3>

We need to get the equation that rules the points given on the table. Two-Point Form of the Equation of a Line is:

y-y_{1}=m(x-x_{1}) \\ \\ We \ know \ m=3 \\ \\ y-5=3(x-1) \therefore y-5=3x-3 \therefore y=3x+2

As you can see y=6x+4 has a y-intercept of b=4 while the function of the table has a y-intercept of b=2

<em> In conclusion,</em> y=6x+4 <em>also has the greater y-intercept</em>

Convert 525 pounds to kilograms.Show your dimensional analysis setup. 1 kilogram=2.2 pounds.
Ostrovityanka [42]

In this case, the starting amount is 525 pounds. You want to convert it into kilograms so you need to know the equal amount of pounds into one kilogram. The equal amount is: 1kilogram/ 2.2 pounds.

To convert it you simply need to multiply the starting amount with the equal amount, then the calculation is:
525 pounds x 1 kilogram/2.2pound= 525 kilogram / 2.2= 238.63 kilograms.

Then the end amount is 238.63 kilograms
