How do you work out the gradient of a line?

Answers

Answer 1

Step-by-step explanation:

The gradient of the line = (change in y-coordinate)/(change in x-coordinate) . We can, of course, use this to find the equation of the line. Since the line crosses the y-axis when y = 3, the equation of this graph is y = ½x + 3 . To find the gradient of a curve, you must draw an accurate sketch of the curve.

Step-by-step explanation:

The fourth diagram  show lines that must be parallel lines cut by a transversal

What is Straight line?

A line is an infinitely long object with no width, depth, or curvature.

Parallel lines  refers to two lines which can be found on the same plane, at an equidistance and does not meet.

A transversal is defined as a line that passes through two lines in the same plane at two distinct points in the geometry.

The fourth diagram has two same-side interior angles that are supplementary (add to 180°).

The converse of the same-side interior angle theorem states that if two lines are cut by a transversal and the same side interior angles are supplementary, then the lines are parallel.

Hence, the fourth diagram  show lines that must be parallel lines cut by a transversal

Morris borrowed $6 from his mother. so far, he has repaid $4. if debt is represented as a negative number, what number sentence shows the amount of jack's remaining dept.?

Answers

if it was negitive I would be -2

Step-by-step explanation:

so 6-4=2 and if you make that negative it would be -2

Answer:

-$6 + $4 = -$2

Step-by-step explanation:

Since Morris borrowed 6 dollars to begin with, the first term in my equation is -6$, representing the debt he has incurred from taking a loan of 6 dollars from his mother. After paying $4 dollars, he would still be in debt of $2 to his mother. Since he is still in debt of 2 dollars, the furthest right term in my aforementioned equation is -$2.

What is an area of a circle?

Area of a circle is defined as the region occupied by the circle in two-dimensional plane.

Mathematically,

                         A = π (d/2)²

where d is the diameter of circle

or,                      A = π r²  

where r is the radius of circle.

Now, given diameter of tortilla is 8inches.

⇒ d  = 8inches

Since,tortilla is a circle

So, area of tortilla A = π (d/2)²

⇒ A = π (8/2)²

⇒ A = π (4)²

A = 16π square inches

Hence, required tortilla's area is 16π square inches.

An angle measures 107.8° less than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

x=36.1

supplementary angle = 143.9 degrees

Step-by-step explanation:

angle: x

supplementary angle: 180-x

x = (180-x)-107.8

2x = 72.2

x = 36.1 degrees

180-x =  143.9 degrees

supplementary angle = 143.9 degrees

x measures 107.8 less than 180-x

x=180-x-107.8

x=72.2-x

Add x to both sides

2x=72.2

Divide both sides by 2

x=36.1

F(x)=|x+6| 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.Write a complete and accurate summary of this text.
