Answer:
416Step-by-step explanation:
For this to have infinitely many solutions, the left side and right side must simplify to the same expression. The left side is already simplified, so we need to find the right numbers for the right side.
Coefficient of x:
7x = __x + 3x
4x = __x . . . . . . subtract 3x; next divide by x
4 = __ . . . . . the required x-coefficient is 4
Constant term:
-8 = 8 -__
-16 = -__ . . . . . subtract 8
16 = __ . . . . . . multiply by -1
__
The numbers that go in the boxes are 4 and 16.

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)
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]

b) Based on the table, what is the maximum

height the blue shell reaches?
Answers
Answer:
1. I assume you just pick some arbitrary x and y numbers to plug in the equation. but if you answer part b and c first, part a might be easier for what values to choose.
2. if you do a quick browser search for how to find the max height of a parabola, then you can learn how to.
3. research on Browser. you can also just make y = 0.
vertex is max height, both zeros is just solving the equation for the x values. axis of symmetry is just the vertex point with a line through it.

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:
Vapor pressure of the solution is 22.9 torr at 25°C

8(-3y)+9y=20
-24y+9y=20
-15y=20
y=20/-15
simplify
y=-4/3
x=-3(-4/3)=12/3=4
Answer:
Y=4/-3 X=4
Step-by-step explanation:
We must use substitution. If x is -3y, then we can either substitute all the x’s or y’s. I’ll substitute y.
8x+9y=20
8x+-3x=20
5x=20
x=4
x=-3y, so -3y=4. Y=4/-3

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
