Answer:
D: (2, -3)
Step-by-step explanation:
We have;
y = 3x - 9 - - - (1)
y = -2x + 1 - - - (2)
By substitution method, from eq 1, we see that: y = 3x - 9
Thus,let's put 3x - 9 for y in eq 2;
3x - 9 = -2x + 1
Rearranging to get;
3x + 2x = 9 + 1
5x = 10
x = 10/5
x = 2
Thus;
y = 3(2) - 9
y = 6 - 9
y = -3
Thus,the solution (x, y) = (2, - 3)

Hope it is helpful...Alex was trying to determine how much money he owed the bank. Since his checking account has a balance of -155 dollars, he thinks that he can find the absolute value of -155 to determine that he owes the bank 155 dollars. Is Alex correct?
Answer:
Alex is correct.
Step-by-step explanation:
In order for Alex to get to $0, meaning he owes the bank nothing, he has to add 155 dollars to negative 155 dollars, because this means he has no debt left. The absolute value of -155 is 155 and if Alex pays the 155 dollars, he will not have to pay anything else to the bank.
A restaurent pays a water R18 per hour in one week he worked a shift from 12h00 to 23h00 Calculate the number of hours the water works per shift
Answer:
Number of hour work per shift = 11 hour per day
Amount paid for one shift = Rs 198
Step-by-step explanation:
Given:
Amount pay per hour = Rs 18
Shift time = 12 h to 23 h
Find;
Number of hour work per shift
Amount paid for one shift
Computation:
Number of hour work per shift = 23:00 - 12:00
Number of hour work per shift = 11 hour per day
Amount paid for one shift = Number of hour work per shift x Amount pay per hour
Amount paid for one shift = 11 x 18
Amount paid for one shift = Rs 198

A box is filled with several party favors. It contains 12 hats, 15 noisemakers, 10 finger traps, and 5 bags of confetti. Let H = the event of getting a hat. Let N = the event of getting a noisemaker. Let F = the event of getting a finger trap. Let C = the event of getting a bag of confetti. Find P(N).
Answer:
P(N) = 5/14
Step-by-step explanation:
Find P(N) by finding the probability of getting a noisemaker.
There are 42 items in total, and 15 are noisemakers. Find the probability by dividing 15 by 42:
15/42
Simplify:
5/14
So, P(N) = 5/14
Give the set of four quantum numbers that could represent the last electron added (using the Aufbau principle) to the Cl atom.A) n=3, l=1, ml=1ms=+12B) n=3, l=0, ml=1, ms=−12C) n=3, l=2, ml=1, ms=+12D) n=2, l=1, ml=1, ms=−12E) n=3, l=1, ml=1, ms=−12
Answer:
n=3, l=1, ml=1ms=+1/2
Step-by-step explanation:
The electron configuration of chlorine atom is; [Ne] 3s² 3p⁵.
This means that the last electron is found in a 3pz orbital.
We can see that the principal quantum number is 3. The electron is in a p orbital so l=1, the electron must be found in a 3pz orbital hence ml=1. The electron is found alone in that orbital hence s= 1/2.

Step-by-step explanation:
Using visual inspection, the bar of North HS is 5 times longer Than the bar of West HS.
The gtids are of equal size, West HS occupies one portion of the grid, while North HS occupies 5 portions of the grid
5 portions / 1 portion = 5
Hence, North HS according to the graph is 5 times West HS
Hermione thinks she has discovered a protection spell that will reduce the pain of the Cruciatus curse. She believes that a sample of people protected by her spell will rate their pain as less severe than the average person who does not have her protection spell. Her null hypothesis for this study would
Answer:
There will be no difference in pain ratings from people protected by her spell and people who aren't protected by her spell.
Step-by-step explanation:
The claim in this scenario is the alternative hypothesis, which is what we wish to test ; the alternative hypothesis is thus ; people who are protected by spell will rate their pain as a result of cruciatus curse as less severe than the average person who does not use her protection spell ;
As we know, the null hypothesis is the opposite of the alternative hypothesis and the initial truth, which is ;
The average pain felt by both the user of the pain protections spell and those who do not feel the same amount of pain.

Use substitution to solve the following system of linear equations and fill in the following blanks:
x + y + z = -6
x - 6y - 7z = -29
-7y - 5z = 4
In the first step, select Equation 1 and find an expression for variable X in terms of other variables:
x = - y -z - 6
Then substitute X in Equation 2. The result is the following new equation:
___y+___ z = -23
In the last step, using back-substitution, the solution for this system is:

Answer:
[tex]x=-4[/tex]
[tex]y=3[/tex]
[tex]z=-5[/tex]
Step-by-step explanation:
Given:
[tex]x+y+z=-6[/tex]
[tex]x-6y-7z=-29[/tex]
[tex]-7y-5z=4[/tex]
Solve for [tex]x[/tex] in the 1st equation:
[tex]x+y+z=-6[/tex]
[tex]x+y=-z-6[/tex]
[tex]x=-y-z-6[/tex]
Substitute the value of [tex]x[/tex] into the 2nd equation and solve for [tex]z[/tex]:
[tex]x-6y-7z=-29[/tex]
[tex](-y-z-6)-6y-7=-29[/tex]
[tex]-7y-z-13=-29[/tex]
[tex]-7y-z=-16[/tex]
[tex]-z=-16+7y[/tex]
[tex]z=16-7y[/tex]
Substitute the value of [tex]z[/tex] into the 3rd equation and solve for [tex]y[/tex]:
[tex]-7y-5z=4[/tex]
[tex]-7y-5(16-7y)=4[/tex]
[tex]-7y-80+35y=4[/tex]
[tex]28y-80=4[/tex]
[tex]28y=84[/tex]
[tex]y=3[/tex]
Plug [tex]y=3[/tex] into the solved expression for [tex]z[/tex] and evaluate to solve for [tex]z[/tex]:
[tex]z=16-7(3)[/tex]
[tex]z=16-21[/tex]
[tex]z=-5[/tex]
Plug [tex]z=-5[/tex] into the solved expression for [tex]x[/tex] and evaluate to solve for [tex]x[/tex]:
[tex]x=-(3)-(-5)-6[/tex]
[tex]x=-3+5-6[/tex]
[tex]x=2-6[/tex]
[tex]x=-4[/tex]
Therefore:
[tex]x=-4[/tex]
[tex]y=3[/tex]
[tex]z=-5[/tex]

Answer: The answer is D
Step-by-step explanation:
You add z to the other side then it will cancel out which then it would be (w+z) and then you times it by 2 by both sides which would be 2(w+z) and then you would subtract x from both sides which will be 2(w+z)-x

8) Find the midpoint of the equation y = 4x + 6 between the x-intercepts and the y-intercepts.
9514 1404 393
Answer:
(-3/4, 3)
Step-by-step explanation:
I find it easier to determine the intercepts when the equation is in standard form:
4x -y = -6
The x-intercept is found where y=0:
4x = -6 ⇒ x = -6/4 = -3/2
The y-intercept is found where x=0:
-y = -6 ⇒ y = 6
Then the midpoint is ...
M = ((-3/2, 0) +(0, 6))/2 = (-3/4, 3)
