I’m working on 3 and 4 only maybe if I can have some explanation so I can understand and do more of these next week.
guapka [62]

4.b.

Answer:  See below.

Step-by-step explanation:

<h2><u>For the equation f(x) = 2x</u></h2>

3.a.  f(6) means use x = 6 in the equation f(x) = 2x

so f(6) would be f(6)= 2(6)

<u>f(6) = 12</u>

3.b.  f(-11) = 2(-11)

<u>f(-11) = -22</u>

3.c.  f(2.75) = 2(2.75)

<u>f(2.75) = 5.5</u>

3.d.  This is turned around.  We are told f(x)=20, so what would x need to be for f(x) to be 20?  Since f(x) = 2x, we can say 20 = 2x.  Therefore x = 10

f(10) = 20

<u>The rest of (3) are solved in the same fasion.h</u>

<u></u>

<h2><u>For the equation  f(x)= 5x+50</u></h2>

4.a.  f(7) = 5(7)+50

<u>f(7) = 85</u>

4.b. f(-12)

  f(-12) = 5*(-12)+50

<u>f(-12) = -60</u>

<u></u>

Continue in the same fashion for these types of problems.

As a bicycle salesperson, Norman earns a fixed salary of $20 per week plus $6 per bicycle for the first 6 bicycles he sells, $12
wlad13 [49]

Answer:

A. I only

I. y>2x

Step-by-step explanation:

I. y>2x

He sold x bicycles last week and y bicycles this week,  this week, he earned more than twice as much as he did last week. Therefore more than twice means greater than 2 x or

y>2x

II. y>x This is not true because y could be greater than x and less than twice of x (2x)

III. y>3 This is also not true because the least he would be earning would be $ 20 and he could get earn greater than 3 and less than $ 20 which would again be contradictory to the given statement
