Division first:

-2/5 / 8/15

When dividing two fractions flip

The second one over and multiply:

-2/5 x 15/8 = (-2x15)/(5x8) = -30/40 = -3/4

Now you have:

2-3/4-3/4

2-3/4 = 1 1/4

1 1/4 - 3/4 = 1/2

The answer is 1/2

Hey there!!!

Here,

The point is, (-3,1).

Using one point formula.

(y-1)= m(x+3)....1st equation.

It has said that it is also perpendicular to the line y = 1/3x + 2 .......2nd equation.

Now, the equation with y = mx + c.

We get slope (m2) = 1/3.

Now,

As per the condition of perpendicular lines,

[tex]m1 \: \times m2 = - 1[/tex]

[tex]m1 \times \frac{1}{3} = - 1[/tex]

Simplifying them we get,

m1 = -3.

Therefore the slope is -3.

Answers

Answer:

100

Step-by-step explanation:

Think of the absolute of a number as the distance from that number to zero on the number line. The distance from 100 to 0 on the number line is 100, so absolute value of 100 is 100. Notice that -100 is also at a distance of 100 from zero, so |-100| = 100.

-2x+y=4
You can answer no solution or infinitely many

Answers

Answer:

x = -3.3333333

y = -2.666666

Step-by-step explanation:

y = 1/2 x - 1

y = 2x + 4 The second equation has the 2x moved to the right side. The y's must be equal so equation the two equations.

1/2x -1 = 2x + 4             Subtract 1/2x from both sides.

-1 = 2x - 1/2 x + 4          Combine

-1 = 1.5x + 4                   Subtract 4 from both sides

-1 - 4 = 1.5x

- 5 = 1.5x                       Divide both sides by 1.5

-5/1.5 = x

x = - 3.333333

Now put x = - 3.333333 into either one of the two given equations. The first one will require one less step, but it does not matter.

y = 1/2 (- 3.3333333) - 1

y = - 1.6666666 - 1

y = -2.6666666

An investment company pays 7​% compounded semiannually. You want to have $24000 in the future. ​ How much should you deposit now to have that amount 5 years from​ now?

Answers

Answer: You should deposit about $17014 or little more

Step-by-step explanation:

use the compound interest formula.

A= p( 1 + r/n)^nt

Where A is the amount you will save over some  years .

p is the principal or start up  amount mostly known as the initial fee.

r is the interest rate represent by a decimal so 7% will be 0.07.

n is the number of times the interest is being applied annually. Semiannually means  twice.  So n will be 2.

T is the time the money will elapsed. So in 5 years the money will elapse. Now input the values into the formula and solve for p the principal.

24,000 = p( 1 + 0.07/2)^2*5

24,000= p( 1 + 0.035)^10

24000 = p( 1.035)^10

24000 = p( 1.41059876062)  Divide both sides by 1.41059876062

p = 17104  

Which means you should deposit about $17014 or little more

What is the missing statement and the missing reason in step 5? A 2-column table with 7 rows. Column 1 is labeled statements with the entries measure of angle A D E = 60 degrees and measure of angle C D F = (3 x + 15) degrees, angle A D E and angle C D F are vertical angles, angle A D E is-congruent-to angle C D F, measure of angle A D E = measure of angle C D F, question mark, 45 = 3 x, and, 15 = x. Column 2 is labeled reasons with the entries given, definition of vertical angles, vertical angles congruent, definition of congruency, question mark, subtractive property, division property. Statement: 60 = 3x + 15; Reason: substitution Statement: x = 15; Reason: subtraction property of equality Statement: 60 = 3x + 15; Reason: transitive property Statement: x = 15; Reason: subtraction and division properties of equality

Answers

Answer:

Statement: 60 = 3x + 15; Reason: substitution

(aka A)

Step-by-step explanation:

The missing statement and the missing reason in step 5 is;

Statement: 60 = 3x + 15;   Reason: substitution

Here,

We have to find the missing statement and missing reason.

What is Substitution method?

Substitution method is algebraic method to solve the linear equations .

Now,

Column 1 and column 2 are labeled here as;

Angle A D E = 60 degrees                ( entries given)

Angle C D F = (3 x + 15) degrees

Angle A D E and Angle C D F are vertical angles.  (definition of vertical angles)

Angle A D E is-congruent-to Angle C D F.  ( definition of congruency)

Measure of angle A D E = Measure of angle C D F.

 60 = 3x + 15      ( substitution )

⇒  45 = 3 x            ( subtractive property )

⇒  15 = x             ( division property )

Hence, The missing statement and the missing reason in step 5 is;

Statement: 60 = 3x + 15;   Reason: substitution

Nothing ConstantNothing is constant but change.Heraclitus, an ancient Greek philosopher1 It was the last day of school; the kids were gone, the books had been collected, and Principal Drake was handing out final paychecks. This was normally a relaxed meeting at which teachers wearing casual clothes smiled and wished each other well for the summer. But no one was smiling today, because a story in the local newspaper had exploded like a crack of thunder.2 The headline read, Board of Education Plans New Middle School, and the staff members of East Orange Elementary were rattled.3 Principal Tom Drake opined, I am concerned about a situation in which a newspaper already knows school district information that comes as a surprise to me and my teachers. He continued, But of far greater concern is what this means for us, for our colleagues at West Orange, and for students and parents throughout the district.4 Coach Melinda Gardner whispered to her friend, Mr. Dale French, Old Tom is just worried the Board might ask him to retire and make someone else principal of the new campus.5 Mr. French whispered back, Melinda, you be nice now, but he couldnt help smiling at his friends remark.6 As the meeting went on, many teachers worried out loud about what might happen if grades 6-8 from East and 6-8 from West consolidated.7 Ever since the two elementary schools had opened, decades ago, the district had proudly maintained a unique system. While surrounding districts had built new middle schools, Orange kept two elementary buildingsEast and Westwith K-8 graders in each.8 Now, according to the paper, the results of the 2010 census were in. They suggested population growth would soon fill both elementary schools with K-5 students only. Apparently, the Board thought the time was ripe to build one new middle school for 6-8 graders.9Will one campus need two middle school science labs? Dr. Fred Davis, the science department head, asked the group in his usual shy, quiet voice.10Since there is only one middle school library, is the Board going to honor seniority? Mrs. Betty Green asked brashly. Or the Board could just keep whichever librarian has the coolest photos on her social media site, she added sarcastically.11Mrs. Green is worried her lack of computer skills might finally hurt her, Coach Gardner whispered to Mr. French again.12Coach Gardner, please! Principal Drake scolded his gym teacher for whispering. You would not tolerate it if your students were rude. This turn of events has caused real alarm so lets be sensitive to each others concerns.13I apologize for both of us, Tom, Mr. French offered. But lets not get carried away and spoil our summers over this. We dont know if this proposed new campus will actually be built. The census projections could be wrong. Even if they are right, the cost of raising taxes to pay for a new school might not go over well with voters.14 Mr. French continued, I plan to enjoy my summer and expect another great year. Chances are well all have jobs because several teachers retire every year and the Board moves us around to fill the vacancies. Some of us may have new assignments, but well all land somewhere.15 All around the room there were nods of agreement. The atmosphere of gloom gave way to the usual feelings of accomplishment and relief at the end of school.16 Mr. French offered one more uplifting thought. Each spring we graduate our eighth graders and send them on to Central High. If they can adjust to a new building, I think we can too.17 With that, the teachers adjourned and summer vacation began.Which sentence from the text BEST supports the idea that some teachers fear their livelihood is being threatened? A. "Will one campus need two middle school science labs?" B. "Or the Board could just keep whichever librarian has the coolest photos on her social media site." C.
