None they're parallel because they have te same slope. Work; get y by itself or graph! hope it helped ;)

Which of the following is the correct graph of the compound inequality 4p + 1 > −15 or 6p + 3 < 45?

astraxan [27]

Answer:

4p + 1 > −15 or 6p + 3 < 45

has solution any number.

The graph looks like this

<~~~~~~~~~~~~~~~~~~~~~~~~~~~>

---------(-4)---------(7)-------------

The shading is everywhere from left to right.

Step-by-step explanation:

Let's solve this first:

4p+1>-15

Subtract 1 on both sides:

4p>-16

Divide both sides by 4:

p>-4

6p+3<45

Subtract 3 on both sides:

6p<42

Divide both sides by 6:

p<7

So our solution is p>-4 or p<7

So let's graph that

~~~~~~~~~~~~~~~~~~~~~~~~~~~~O

O~~~~~~~~~~~~~~~~~~~~~~~~~~~~ p>-4

---------------------(-4)---------------------(7)--------------------

or is a key word! or means wherever the shading exist for either is a solution.

So this shading is everywhere.

The answer is all real numbers.

The final graph looks like this:

<~~~~~~~~~~~~~~~~~~~~~~~~~~~>

---------(-4)---------(7)-------------

The shading is everywhere from left to right.

The table below represents how Marco feels about chocolate candy bars.

kvasek [131]

Answer:

The satisfaction level gained when a customer consumes a product is total utility.It calculated by finding the total sum of utility from consumption.

Marginal utility is the rate of change of total utility and quantity consumed.

Here you apply the expression, Marginal utility=change in total utility/change in quantity consumed

Let, Marginal utility=MU

Total utility=TU

Quantity consumed=QC

Then MU=ΔTU ÷Δ QC

Given the table

Chocolate Candy Bars Total Utility(utils) Marginal Utility(utils)

0 0 -

1 25  x

2  y  17

3 54 z

4  a   b

5 66 4

6  c  -1

Here you have assigned the missing areas with letter, hence finding the real values of the letters;

Apply MU=ΔTU÷ΔQC

$1.17=\frac{y-25}{1}\\\\17=y-25\\\\y=17+25=42\\\\\\2.x=\frac{25-0}{1} \\\\x=25-0=25\\\\\\3.z=\frac{54-42}{1} \\\\z=54-42=12\\\\\\4.\frac{66-a}{1} =4\\\\66-a=4\\\\66-4=a\\a=62\\\\5.b=\frac{62-54}{1} =8\\\\\\6.\frac{c-66}{1} =-1\\\\\\c-66=-1\\\\c=-1+66=65$

Answers

y=42,x=25,z=12,a=62,b=8,c=65
