Which of the following is the midpoint of segment
AB
given that
A(−5,12) and B(3,−8)

Answers

Answer:

(-1, 2)

Step-by-step explanation:

Finding the midpoint of a line, having been given two points, is like finding the average coordinate of those two points.

To find the average x coodinate (and hence the midpoint's x coordinate), you have to sum the x coordinates and divide by 2 - like finding the mean.

To find the y coordinate, sum the y coordinates and divide by two.

If you divide my number by "-5 and add -2, the result is -4. What's my number?

Answers

Answer:

10

Step-by-step explanation:

10/-5 = -2

-2+-2 = -4

Answer:

10

Step-by-step explanation:

First, arrange this word problem as an equation. Using N as the unknown number, we see:

(N/-5) + (-2) = -4

Next, we add -2 to both sides of the equation:

(N/-5) = -2

Now multiply both sides by -5:

N=10

What is the equation of a line that passes through the points 0,5 and 4,8 in slope intercept form

Answers

Answer:

y = 3/4 + b

Step-by-step explanation:

To get slope intercept form you need to have the y = then you need to find the slope which is y2 - y1 and x2 - x1, find the answer whether it be a fraction or a whole number. And since you don't know the y-intercept you mark the last integer as b, since you don't the answer. So it comes out to y = 3/4 + b

y = (3/4)x + 5

Using the two coordinates, you can find slope and y-intercept

y-intercept is 5, from the point (0,5)

slope is 3/4, from rise/run, and that 0 to 4 is 4, while 5 to 8 is 3.

Combine slope and y-intercept for slope intercept form

y = (3/4)x + 5

Find the inverse of the matrix (if it exists). (If the answer does not exist, enter DNE in any cell of the matrix.)

Answers

Answer:

[tex]\begin{pmatrix}-15&-28\\ -8&-15\end{pmatrix}[/tex]

Step-by-step explanation:

[tex]\begin{pmatrix}a\:&\:b\:\\ c\:&\:d\:\end{pmatrix}^{-1}=\frac{1}{\det \begin{pmatrix}a\:&\:b\:\\ c\:&\:d\:\end{pmatrix}}\begin{pmatrix}d\:&\:-b\:\\ -c\:&\:a\:\end{pmatrix}[/tex]

This is the formula we will use. Accordingly:

[tex]=>\frac{1}{\det \begin{pmatrix}-15&28\\ 8&-15\end{pmatrix}}\begin{pmatrix}-15&-28\\ -8&-15\end{pmatrix}[/tex]

det represents the determinant

if the determinant is 0 then only the inverse matrix will not exist. So let's find the determinant.

[tex]\det = \left(-15\right)\left(-15\right)-28\cdot \:8\\ = 1[/tex]

Now we multiply the following matrix by 1/1:

[tex]\frac{1}{1}\begin{pmatrix}-15&-28\\ -8&-15\end{pmatrix} = \begin{pmatrix}-15&-28\\ -8&-15\end{pmatrix}[/tex]

Step-by-step explanation:

your answer is:  22.9 torr at 25°C

Explanation:

When a non volatile solute is added to a pure solvent, the vapour pressure of the mixture decrease regard to the pure solvent following the equation

Where vapour pressure of the pure solvent (Water) is 23.8torr at 25°C.

Mole fraction of water is the ratio between moles of water and total moles in solution. The solution has a mole fraction of water of:
