12. Determine the slope of the line having the equation 2x + y = 12
a. 2
b. -2
c. ½
d. -½​

Answers

Answer 1

Answer:

b. -2

Step-by-step explanation:

Note the slope-intercept form: y = mx + b

Note that:

y = (x , y)

m = slope

x = (x , y)

b = y-intercept

First, isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 2x from both sides of the equation:

2x (-2x) + y = (-2x) + 12

y = -2x + 12

Remember, m is the variable for the term that stands for the slope (directly next to the x variable). In this case, your answer will be -2

b. -2 is your answer.

~

Answer 2

Answer:

b. -2

Step-by-step explanation:

2x+y=12

add -2x to both sides

y = -2x + 12

this is in slope intercept form y = mx + b

m meaning the slope

in this case the slope is -2

the answer will be b. -2

a. He multiplied the reciprocals of both fractions.
b. He added -3/4 and 1/4
c. He multiplied-3/4 by 1/4
d. He multiplied using the reciprocal of -3/4.





Answers

The correct quotient is -3

The mistake CJ likely made is multiplying using the reciprocal of -3/4. The correct option is d. He multiplied using the reciprocal of -3/4

From the question,

We are to determine the correct quotient.

The given division operation to be carried out is -3/4 divided by 1/4

The correct quotient can be determined as shown below

[tex]-\frac{3}{4} \div \frac{1}{4}[/tex]

Multiply [tex]-\frac{3}{4}[/tex] by the reciprocal of [tex]\frac{1}{4}[/tex]

The reciprocal of [tex]\frac{1}{4}[/tex] is  [tex]\frac{4}{1}[/tex]

Then, we get

[tex]-\frac{3}{4} \times \frac{4}{1}[/tex]

This gives

[tex]-\frac{12}{4}[/tex]

= -3

The correct quotient is -3

The mistake CJ likely made is multiplying using the reciprocal of -3/4.

Hence, the correct quotient is -3

The mistake CJ likely made is He multiplied using the reciprocal of -3/4. The correct option is d. He multiplied using the reciprocal of -3/4

Consider the following two loans for P=$12,000.

Loan A: 5 year loan, annual interest rate of 5%.
Loan B: 3 year loan, annual interest rate of 8%.

Answers

Answer:

Simple interest-?

Step-by-step explanation:

P= 12000

T=5yrs

R=5%

Now,

Simple interest - PTR/100

= 12000*5*5/100

= $3000

Again,

P=12000

T=3yrs

R=8%

Now,

Simple interest - PTR/100

= 12000*3*8/100

= $2880

Since we want to find the value of k where the limit exists, set both equations equal to each other. Then substitute x = -1 in for each equation to find k.

1. Set both equations equal.

[tex] - k - 3 = 1 + k[/tex]

2. Substitute x = -1.

Answer:

-1;undefined;1;0

Step-by-step explanation:

The first one (-9/9), can also be written as - 9/9 = - 1.

The second one (9/0), is undefined because every single term even 0 itself, if you divide it by 0, it'll be undefined!

The third one, we see we have division, and whenever we have division or multiplication and also 2 negative signs, they cancel each other, as you're left with 9/9=1.

The fourth one, whenever you have 0 at the numerator, no matter the denominator(only matters when it's =0, but that's undefined), the result will always be 0 !

Enter an equation in standard form to model the linear situation. A bathtub that holds 41 gallons of water contains 11 gallons of water. You begin filling it, and after 5 minutes, the tub is full.

Answers

Answer: In this equation, let "x" equal the rate at which the tub will be filled. The tub holds 32 gallons, which will be one-half of the equation. The tub already contains 12 gallons, so this will be half of the other side of the equation. The rate is "x" gallons per minute, and the time it required was 5 minutes, so this would be "5x". Placing all these parts together gives an equation of (32 = 5x + 12) gallons per minute dispensed.

If 87 people attend a concert and tickets for adults cost $3.5 while tickets for children cost $3.25 and

total receipts for the concert was $291.75, how many of each went to the concert?

Answers

Answer: 51 Children and 36 Adults.

Step-by-step explanation: Let's call x the number of children admitted and call z the number of adults admitted.

We know that x+z= 87

We also know that 3.25x+3.5z= 291.75.

We want to find the value of x and z. Then we solve the system of equations:

Multiply the first equation by -3.5 and add it to the second equation:

-3.5x-3.5z= -304.5

3.25x+3.5z= 291.75

-----------------------------------------------------------------------------------------------------------------

-0.25x=-12.75

x= -42.75 ÷ -0.25

x=51

----------------------------------------------------------------------------------------------------------------

Now we substitute the value of x in the first equation and solve for the variable z

51+z=87

z=87-51

z= 36

Does anyone know 1/4 x ? = -2?
Please scalping on a piece of paper or explain in the comment, that would be really helpful =]

Answers

Answer:

-8

Step-by-step explanation:

1/4 x = -2

You want the value of x. x is being multiplied by 1/4. To get x alone on the left side, you need to divide both sides by 1/4. Dividing by 1/4 is the same as multiplying by 4.

Multiply both sides of the equation by 4.

4 * 1/4 x = -2 * 4

4 * 1/4 = 1, so on the left side you get 1x which is just x.

x = 8

Answer: -8

4. Find PQ. N Р 5x + 16 S R 9x - 32 Q​

Answers

Answer:

76

Step-by-step explanation:

PQRS is a Rhombus.

Property of Rhombus : -

All sides are equal.

So,

PQ = QR = RN = NP

RN = 5x + 16

QR = 9x - 32

QR = RN

5x + 16 = 9x - 32

9x - 32 = 5x + 16

9x - 5x = 16 + 32

4x = 48

x = 48 / 4

x = 12

Substitute x = 12 in RN,

RN = 5x + 16

= 5 ( 12 ) + 16

= 60 + 16

RN = 76

Since,

PQ = QR = RN = NP

Therefore,

PQ = 76

Check all solutions to the equation. If there are no solutions, check "None."
x = 16

Answer:

  y = 0x + 15

Step-by-step explanation:

A line with a slope of 0 is a horizontal line. It has the same y-value everywhere. If it goes through the point (16, 15) with y-coordinate 15, then its y-intercept is 15.

Writing the slope explicitly, the equation is ...

Write the recurring decimal 0.05 as a fraction in its simplest form

Answers

Answer:

1/20

Step-by-step explanation:

Step 1: Write the given number as the numerator and place 1 in the denominator right below the decimal point followed by the number of zeros required accordingly.

In this case, 0.05 has two numbers after the decimal, so, we place 100 in the denominator and remove the decimal point. This will make it 5/100

Step 2: Then, this fraction can be simplified. 5/100 = 1/20

Thus, 0.05 as a fraction is written as 1/20

Answer:

Step-by-step explanation:

let the fraction be a

a*100.....=0.05*100

100a......=05.00

99a....=0.05

100a= 5.00

99a=     0.05

n) Using the given information, determine the medal category in which the United States far outperformed its closest competitor. Show your working to justify your answer.

Answers

The medal category in which the United States far outperformed its closest competitor is the gold medal category.

In order to determine which medal category the United States far outperformed its closest competitor, we need to determine the difference in the medals gotten by the United States and its closest competitor for each medal category. The medal category with the largest difference is the correct answer.

Gold medal

Medals US got = 1022

Medals the closest competitor had = Soviet Union = 440

Difference = 1022 - 440 = 582 medals.

Silver medals

Medals US got = 794

Medals the closest competitor had = Soviet Union = 357

Difference = 794 - 357 = 437 medals

Bronze medals

Medals US got = 704

Medals the closest competitor had = Germany = 349

Difference = 704 - 349 = 355 medals
