k-4/3= 3

Mutiply both sides by 3 .

(3)(k-4/3)= (3)(3)

Cross out 3 and 3 , divide by 3 and then becomes k-4= 9

Move -4 to the other side

Sign changes from -4 to +4

k-4+4= 9+4

k= 13

Answer: k= 13

Describe a real-world situation that the graph could represent. Then describe the possible values for each variable

Alex777 [14]

Answer:

$Speed=distance/time$ i.e. relation between speed-distance-time is one such situation that can be modeled using graph

Step-by-step explanation:

There are many real world examples that can be modeled using graph. Graphs are represented on co-ordinate planes, so any real world example that can be represented by use of linear equation can be represented onto a graph.

One such example, is speed-distance-time relation. Uniform speed can be represented on a graph as shown in figure.

So, the equation for speed is represented by equation as follows:

$Speed=distance/time$

So, if we take distance on y axis and time on x axis with points as (distance,time)

(0,0) ==> $v=0/0=0$

(1,2) ==> $v=1/2=0.5$

(2,2) ==> $v=2/2=1$

the following points 0,0.5,1 will be plotted on graph. Similarly, more values can be plotted by assuming values for distance and time.

NEED HELP FAST PLEASE

Hey!

To solve this equation, we'd first have to apply the distributing rule to this equation.

<em>Original Equation :</em>
$( 3a - 2 )^{2}$

<em>New Equation {Changed by Applying the Distribution Rule} :</em>
$( 3a )^{2} - 2$ · 3a · 2 + $2 ^{2}$

And now we simplify.

<em>Old Equation :</em>
$( 3a ) ^{2} -2$ · 3a · 2 + $2 ^{2}$

<em>New Equation {Old Equation Simplified} :</em>
$9a ^{2}$ - 12a + 4

<em>So, the equation $(3a - 2) ^{2}$ simplified is</em> $9a ^{2}$ - 12a + 4.

Hope this helps!

To buy a car, you borrow $25,000 with a term of three years at an APR of 6.5%. What is your monthly

Finger [1]

Answer:

$766.23

Step-by-step explanation:

The amortization formula is appropriate for this. (Better, use a financial calculator or spreadsheet.)

A = P(r/12)/(1 -(1 +r/12)^-(12t))

where P is the amount borrowed (25,000), r is the annual rate (0.065), and t is the number of years (3).

Putting the given numbers into the formula, we have ...

A = $25,000(0.065/12)/(1 -(1 +0.065/12)^(-36))

A = $25,000(.00541667)/(1 -1.00541667^-36)

A = $25,000(0.00541667)/(0.1767322)

A = $766.23

The monthly payment is $766.23.

A graphing or scientific calculator is useful for these. Something like a TI-84, or any of the equivalents, will have financial calculations like this built in. There are also numerous apps available for phone or tablet that will do financial calculations.

If one three-digit number ( 0 cannot be a left digit) is chosen at random from all those that can be made from the following set

Oksana_A [137]

The probability of choosing a number that is not a multiple of 2 is P = 0.44

<h3 /><h3>How to find the probability?</h3>

We need to count the number of options for each digit.

For the first digit, we have 8 options {1, 2, 3, 4, 5, 6, 7, 8}
For the second digit, we have 9 options {0 ,1, 2, 3, 4, 5, 6, 7, 8}
For the third digit, we have 9 options {0 ,1, 2, 3, 4, 5, 6, 7, 8}.

The total number of combinations is the product between the numbers of options:

C = 8*9*9 = 648

If we want our number to not be a multiple of 2 then it must end in a odd digit, the combinations that meet that condition are:

For the first digit, we have 8 options {1, 2, 3, 4, 5, 6, 7, 8}
For the second digit, we have 9 options {0 ,1, 2, 3, 4, 5, 6, 7, 8}
For the third digit, we have 4 options {1, 3, 5, 7}.

C = 8*9*4 = 288

Then the probability of selecting a 3 digit number that is not a multiple of 2 is:

P = 288/648 = 0.44
