Find the slope of the line passing through the points (-18, -5) and (-19, -13)

Answers

Answer:

Let (-18, -5) be (x1,y1)

(-19, -13) be (x2,y2)

slope = (y2-y1)/(x2-x1)= (-13+5)/(-19 +18) = 8

Answer: The slope is 8.

Step-by-step explanation: To get the slope you have to do y2 - y1 over x2 - x1. so you take the -5 and subtract -13 from it, which equals 8. Then subtract -19 from -18 which is 1. So you have 8/1 which is 8.

what is the median of a triangle ?
pls i need the answer quick

Answers

Answer:

In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid.

Find the product (x+2t) exponent of 2

Answers

Answer:

x² + 4xtx + 4t²

Step-by-step explanation:

Given

(x + 2t)² = (x + 2t)(x + 2t)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x + 2t) + 2t(x + 2t) ← distribute both parenthesis

= x² + 2tx + 2tx + 4t² ← collect like terms

= x² + 4tx + 4t²

Mitch lives on the 20th floor of an apartment building. Every time he leaves, he rides a self-service elevator from the 20th floor to the street; but every time he returns, he rides the same self-service elevator only to the 15th floor, where he leaves the elevator and walks up the remaining five flights of stairs. What is happening? Why does he do that?

Answers

Answer:

He does that because he is short and his hand can't reach the 20th floor button

Step-by-step explanation:

Mitch does that simply because he is short.

When he is leaving, he doesn't need to reach the 20th floor button because the button is way taller than the reach of his hands whereas when he is returning he has to reach the 20th floor button but his hand can only reach the 15th floor button. Thus, he gets to the 15th floor and walks up the remaining 5 flights.

Blanca earns a yearly salary of $55,000. Isabel earns a yearly salary of $63,000. Blanca will receive a salary increase of $3,700 per year, and Isabel will receive a salary increase of $2,900 per year.

Which equation can be used to find n, the number of years it will take Blanca to earn the same salary as Isabel?

55,000n + 3,700 = 63,000 + 2,900n

55,000n + 3,700n = 63,000n + 2,900n

55,000n + 3,700n = 63,000n + 2,900

55,000 + 3,700n = 63,000 + 2,900n

PLSS ANSWER ILL MAKE MOST BRAINLIEST!!!!

Answers

Answer:

last choice: 55,000 + 3,700n = 63,000 + 2,900n

Step-by-step explanation:

Blanca's salary now: 55,000

Adding $3,700 per year will add 3,700n in year n.

Her salary in year n will be 55,000 + 3,700n

Isabel's salary now: 63,000

Adding $2,900 per year will add 2,900n in year n.

Her salary in year n will be 63,000 + 2,900n

We set the two total salaries equal:

55,000 + 3,700n = 63,000 + 2,900n

Suppose S is between R and T. Use the Segment Addition Postulate to solve for z.. RS=2z+6, ST=4z−3, RT=5z+12

Answers

Answer:

Step-by-step explanation:

If S is between R and T, then RS+ST = RT

Given the following parameters

RS=2z+6,

ST=4z−3,

RT=5z+12

On substituting

2z+6+4z-3 = 5z+12

Collect like terms

2z+4z-5z = 12+3-6

6z-5z = 15-6

z = 9

Hence the value of z is 9

This circle is centered at the point (2,6), and the length of its radius is 4. What is the equation of the circle?

Answers

Answer:

The equation of the circle with centre (h,k) and radius (r) can be written as :-

[tex] \\ \qquad \sf \: {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\ [/tex]

So, we are given with :-

h = 2 k = 6 r = 4

Now, by putting their value we can write the equation as :-

[tex] \\ \qquad\sf \: {(x - 2)}^{2} - {(y - 6)}^{2} = {4}^{2} (16) \\ [/tex]

Expanding this, we get :-

[tex] \\ \sf {x}^{2} - 4x + 4 + { y}^{2} - 12y + 36 = 16 \\ [/tex]

Rearranging and by subtracting by 16 from both sides we got standard polynomial as -

[tex] \\ \sf \: {x}^{2} + {y}^{2} - 4x - 12y + 20 = 0 \\ [/tex]

Last summer, Fred earned 16 dollars per day, and Maria earned 18 dollars per day together, they earned 1780 dollars. If Fred worked 5 more days than Maria, how many days did Maria work?

Answers

x = # of days Maria worked

x + 5 = # of days Fred worded

$16(x + 5) + $18x = $1780

Let's distribute the $16

$16x + $80 + $18x = $1780

Combine like terms

$34x + $80 = $1780

Subtract $80 from both sides.

$34x = $1700

Divide both sides by $34

x = 50 days

Maria worked 50 days

I have to find rs and rt

Answers

Answer:

RS= 20

ST= 40

RT=60

Step-by-step explanation:

If you notice, RS and ST make up RT. Therefore, we add RS and ST, and set that equal to RT.

3x-16+4x-8=60 [combine like terms]

7x-24=60 [add both sides by 24]

7x=84 [divide both sides by 7]

x=12

Now that we know x, we can plug them into RS.

We can also find ST.

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We have given that Steve wants to create a system of equations so that the system has no solution.

We know that when both the lines(represented by both the equations) are parallel and not coincident, then that system of linear equations have no solutions as there is no common point on both line.

So the correct option that steve can do are;

A.Create a pair of equations same slope and different y-intercepts.

D. Create a pair of lines that will always stay the same distance apart.

Maya painted 3/4 of her art project in the morning and 1/8 of her project in the evening which equation can Maya use c to find how much of the project she painted

Answers

The equation to find the proportion painted is: [tex]\mathbf{c = \frac{7}{8}x}[/tex]

Let the size of the art be x.

In the morning, she paints 3/4 of x.

So, we have:

[tex]\mathbf{Morning = \frac 34 x}[/tex]

In the evening, she paints 1/8 of x.

So, we have:

[tex]\mathbf{Evening = \frac 18 x}[/tex]

So, the amount of project painted is:

[tex]\mathbf{c = Morning + Evening}[/tex]

This gives

[tex]\mathbf{c = \frac 34x + \frac 18x}[/tex]

Take LCM

[tex]\mathbf{c = \frac{6x + x}8}[/tex]

Add the numerator

[tex]\mathbf{c = \frac{7x}8}[/tex]

So, we have:

[tex]\mathbf{c = \frac{7}{8}x}[/tex]

Hence, the equation to find the proportion painted is: [tex]\mathbf{c = \frac{7}{8}x}[/tex]
