The set of values for y={-3, 0, 5} for given values of x={0, 3, 8} and the equation is 3x-3y=9 and the domain D={0≤x≤8}.

What is Domain?

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f(x). A function's range is the set of values it can take as input. After we enter an x value, the function outputs this set of values.

What is equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign.

The given equation,

3x-3y=9

When x=0, 3*0-3y=9

-3y=9

y=-3

When x=3, 3*3-3y=9

-3y=0

y=0

When x=8, 3*8-3y=9

3y=15

y=5

The set of values for the equation 3x-3y=9 and the domain D=0≤x≤8 is given as x={0, 3, 8} and y={-3, 0, 5}.

Suppose 72% of students chose to study French their freshman year, and that meant that there were 378 such students. How many students chose not to take French their freshman year?

Answers

The number of students who chose not to take French their freshman year is 147.

According to the question,

We have the following information:

72% of students chose to study French their freshman year.

Now, 72% of students is equal to 378.

Let's take the number of students to be x.

So, we have:

72x/100 = 378

72x = 378*100

x = (378*100)/72

x = 525

Now, we have to find the number of students who chose not to take French their freshman year:

(100%-72%)

28%

Now, we have to find the 28% of total number of students:

(28*525)/100

14700/100

147

Hence, the number of students who chose not to take French their freshman year is 147.

Orlandis earned 2.5% interest on a bank balance of $80. What is the amount of interest earned?

Answers

Given

Bank balance = $80

Interest rate = 2.5%

Amount of interest earned = 2.5% of $80

Amount of interest earned = 2.5/100 of $80

Amount of interest earned = (2.5*80)/100

Amount of interest earned = 200/100

Amount of interest earned = $2.0

Answers

The relation between speed, distance and time is express as :

[tex]\text{ Sp}eed\text{ =}\frac{Dis\tan ce}{Time}[/tex]

Sean and Darryl are racing on a track.

Sean runs 6 miles per hour and gets a 0.25 mile head start.

Speed of Sean = 6

x is the time taken by Sean

So, Distance = speed x Time

Distance travel by sean = 6x

Since, Sean gets a 0.25 mile head start.

So, total distance travel = 6x + 0.25

Darryl runs 0.7 mile per hour faster than Sean,

Speed of darryl = 0.7 + Speed of sean

Speed of daryl = 0.7 + 6

Speed of darryl = 6.7 miles per hour

x is the time taken by Darryl

So, Distance = Speed x Time

Distance = 6.7x

Distance travel by Darryl = 6.7x

Since distance travel by darryl and sean is equal so,

6x + 0.25 = 6.7x

Answer : C) 6x + 0.25 = 6.7x

Due to increased mailing costs, the new rate will cost publishers $50 million; this is 12.5% more than they
paid the previous year. How much did it cost publishers last year? Round to the nearest hundreds.

Answers

The amount it will cost the publishers last year is 44.4 million

How to calculate the amount it will cost the publishers?

The first step is to write out the parameters

The cost of mailing increased for the last one year

Due to this increase, it will cost the publishers $50 million for this current year

The increase is at the rate of 12.5%

The amount it will cost the publishers last year can be calculated as follows

= 12.5/100

= 0.125 + 1

= 1.125

The next step is to calculate last year cost

last year cost= 50/1.125

= 44.4 million

Hence the publishers spent 44.4 million last year

Answers

The equation of the line in slope intercept form  perpendicular to 6x - 2y = 12 and has the same y-intercept is  y = - 1 / 3 x - 6

How to find equation in slope intercept form?

The equation in slope intercept form can be represented as follows:

y = mx + b

where

m = slopeb = y-intercept

Therefore, the equation of the line is perpendicular to 6x - 2y = 12 and have the same y-intercept.

Hence, perpendicular lines follows the rule below:

m₁m₂ = -1

6x - 2y = 12

6x - 12 = 2y

y = 3x - 6

Hence,

3m₂ = -1

m₂ = - 1 / 3

Therefore, the slope of the line is - 1 / 3.

The y-intercept is -6

Therefore,

the equation of the line is y = - 1 / 3 x - 6

as rounding to the nearest cent means rounding to 2 positions after the decimal point.

2.

after 63 months = 5.25 years (t = 5.25)

2000 × (1.025)^(2×5.25) = 2000 × (1.025)^10.5 =

= 2000 × 1.295986825... =

Find the probability of selecting a 10 or diamond when a card is drawn from a standard deck of cards.

Answers

The probability of selecting a 10 or Diamond when a card is drawn from a standard deck of cards is: 17/52

The question asks us to find the probability of picking a 10 or diamond from a deck of cards.

A standard deck of cards contains 52 cards in total.

The deck contains 4 "10s"

And the deck also contains 13 diamond cards.

Thus, we can find the probability of drawing a "10" as:

[tex]P(10)=\frac{n\text{umber of 10s}}{total\text{ number of cards in deck}}=\frac{4}{52}[/tex]

Similarly, we can find the probability of drawing a diamond as:

[tex]P(\text{diamond)}=\frac{n\text{umber of diamonds}}{total\text{ number of cards in deck}}=\frac{13}{52}[/tex]

Now that we have the individual probabilities, we can find the probability of drawing a 10 or a diamond using the OR probability:

[tex]\begin{gathered} P(A\text{ OR B)= P(A) + P(B)} \\ \text{where, A and B are independent events} \end{gathered}[/tex]

Therefore, we can solve the question. This is done below:

[tex]\begin{gathered} \text{Probability of selecting a 10 or a diamond P(10 OR Diamond)=} \\ P(10)+P(\text{Diamond)} \\ \\ \text{But P(10)=}\frac{4}{52} \\ P(\text{Diamond)}=\frac{13}{52} \\ \\ \therefore P(10\text{ OR Diamond)=}\frac{4}{52}+\frac{13}{52}=\frac{17}{52} \end{gathered}[/tex]

Thus, the probability of selecting a 10 or Diamond when a card is drawn from a standard deck of cards is: 17/52

The equation of the line that passes through point (8,-1) and perpendicular to 8y = x - 16 is f(x) = -8x + 63.

What is the equation of line that passes through the given points and is perpendicular to the given line?

Given the data in the question;

Equation of line: 8y = x - 16Point: (8,-1)

First we determine the slope of the initial line using the slope intercept-form. y = mx + b

8y = x - 16

y = (1/8)x - 2

Compared with the slope intercept form,

Slope m = 1/8

Now, for the equation of line perpendicular to the initial line, its slope must be a negative reciprocal of the initial slope.

Hence, slope of the perpendicular line is;

Slope m = -1/1/8 = -8

To find the equation of the perpendicular line, we use the point slope formula.

y - y₁ = m( x - x₁ )

Plug in the slope m ( -8) and point (8,-1).

y - (-1) = (-8)( x - 8 )

y+1 = -8x + 64

y = -8x + 64 - 1

y = -8x + 63

Therefore, the equation of the perpendicular line is y = 8x + 63
