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

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:
Replacing in Raoult's law:

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

Jerry buys t-shirts for $6 each and marks up the price by 45%.
How much profit does Jerry make from each t-shirt sold?
help pleaseee
Answers
Answer:
$2.70
Step-by-step explanation:
to find out he marks up each shirt by, just do 45% of 6 or 0.45 * 6 = $2.70
If Jerry buys a t-shirt for $6 and sells it for 45% more than she bought it, then jerry is selling them for $8.70 and making $2.70 for each t-shirt she sells, because 45% of 6 is 2.7
You can find this answer by multiplying the percentage by the number (.45 x 6)
