What equation represents the slope intercept from the line below y intercept ( 0, 2) slope -3/7 ( PLEASE HELP FAST TOP ANSWER GETS BRAINLIEST!!)

Answers

Answer 1

Answer:

Answer:

$\boxed{Option \ A}$

Step-by-step explanation:

y-intercept = b = 2 [y-intercept is when x = 0]

Slope = m = -3/7

Putting this in slope-intercept equation

=> $y = mx+b$

=> $y = -(3)/(7)x + 2$

Find the slope. ( include whether positive or negative.)

Answers

Answer:

that is a negative slope

but dont know how to find the slope sorry

Step-by-step explanation:

$\tt Step-by-step~explanation:$

Remember: To find the slope, we use the equation Rise/Run.

$\tt Step~1:$

Let's find the rise first. Rise = How many units it goes up/down We can count down 6 units from the origin. Our rise is - 6.

$\tt Step~2:$

To find the run. we count left/right. We could count 8 units. Our run is 8.

The slope is negative because it slopes downwards. If the slope is positive, then the line would be rising up.

$\tt Step~3:$

To find the slope, we use the formula rise/run.

$\tt (-6)/(8)=-(3)/(4)~or~ -0.75$

$\large\boxed{\tt Our~final~answer:~m=-(3)/(4)~or~-0.75;~Negative~slope}$

Tammy is at the dentist's office waiting on her appointment. She notices that the 6-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle.Part 1: How many radians does the minute hand move from 1:20 to 1:55? (Hint: Find the number of degrees per minute first.)
Part 2: How far does the tip of the minute hand travel during that time?
Part 3: How many radians on the unit circle would the minute hand travel from 0° if it were to move 5π inches?
Part 4: What is the coordinate point associated with this radian measure?

Answers

PART 1:55-21=35
35/60=.58333
360×.58333 =210 DEGREES
210*pi/180 = 3.665 RADIANS

PART 2: (pi) x 2r x .58333
3.14 x 12 x .58333 = 21.98 in

PART 3: 5π inches = 5 x 3.14 = 15.708 inches / 6 in radius = 2.618 radians

PART 4: 2.618 radians * 180/pi = 150°
x coordinate = 6(cos 150°) = -5.196
y coordinate = 6(sin 150°) = 3
the coordinates would be (-5.196, 2)

Answer:

Part 1:

In order to find how many radians the minute hand moves from 1:20 to 1:55, we need to remember that there are 60 minutes in an hour (clock) and there are 360 degrees in the clock since the clock is a circle. After dividing 360 by 60, we find that each minute is equal to 6 degrees. After that, we can subtract the times, which tells us that there are 35 minutes between 1:20 and 1:55. Using this we can just multiply this out, to get 35 times 6, which is equal to 210 degrees. We can get our final answer by converting this into degrees. Since one 1 degree is about 0.0174, we can set up a proportion. After solving, we will get that the minutes hand moves 3.555 radians in total.

Part 2:

In order to find how much the minute hand moves, we must find the circumference, so we get c= pi times diameter. Once plugging in the 12, we see that c=37.68. 37.68 is the circumference of the entire clock and since we only need the circumference/length/distance of 35 minutes, we can set up the proportion of 37.68 in./60=x/35 and solve to get 21.98, which means 21.98 is how far the minute hand travels in 35 minutes.

L is the midpoint of MN¯¯¯¯¯¯¯, ML=2x+7 and LN=3x−3. Find ML, LN, and MN.

Answers

Answer:

$ML=27\nLN=27\nMN=54$

Step-by-step explanation:

Since L is the midpoint of MN, by the definition of midpoint:

$ML=LN$

We can picture the following segment:

M----------L----------N

We know that $ML=2x+7$ and $LN=3x-3$ . Since the two segments are equivalent, we can set them equal to each other:

$2x+7=3x-3$

Now, let's solve for x. Subtract -7 from both sides:

$2x=3x-10$

Subtract 3x from both sides:

$-x=-10$

Divide both sides by -1:

$x=10$

So, the value of x is 10.

With this, we can find the remaining lengths.

We know that ML is $2x+7$ .

Substitute 10 for x. So, the length of ML is:

$ML=2(10)+7=20+7=27$

We know that LN is $3x-3$ . So, the length of LN is:

$LN=3(10)-3=30-3=27$

Finally, MN will be the combined lengths of ML and LN. So:

$MN=ML+LN=27+27=54$

And we're done!

The lengths of each segment are:

ML = 27, LN = 27, and MN = 54.

We have,

Let's use the information given to find the values of ML, LN, and MN.

ML = 2x + 7

LN = 3x - 3

L is the midpoint of MN, which means that ML is equal to LN:

2x + 7 = 3x - 3

Now, let's solve for x:

Move the x term to one side of the equation:

2x - 3x = -3 - 7

-x = -10

Now, multiply both sides by -1 to get rid of the negative sign:

x = 10

Now that we have the value of x, we can find the lengths ML, LN, and MN:

ML = 2x + 7

ML = 2(10) + 7

ML = 20 + 7

ML = 27

LN = 3x - 3

LN = 3(10) - 3

LN = 30 - 3

LN = 27

MN = ML + LN

MN = 27 + 27

MN = 54

Thus,

The lengths of each segment are:

ML = 27, LN = 27, and MN = 54.

1+4=5 2+5=12. 3+6=21. 8+11=?

Answers

Hi there this is a puzzle question. So lets get to the answer. If 1+4=5 then we take 1+(4*1)=5. 2+5=12 so lets take 2+(5*2)=12. 3+6=21 so lets take 3+(6*3)=21. After all of this you should probably know now that I multiplied the first number with the second number then added both of the numbers. So, 8+11=8+(11*8)=8+88=96. Therefore, the answer is 96.
