Solve the following system of equations graphically on the set of axes below. y=3x−3 , x+y=5
Answer:
x=2, y=3
Step-by-step explanation:
First, graph both equations on a rectangular coordinate system (see attached screenshot). Then, simply figure out where these two lines intersect. Since they intersect at (2,3), x=2 and y=3.
Plugging these values in the equations for x and y, you can see if these are the correct answers:
(3)=3(2)-3, (2)+(3)=5
Since both of these are true, you have the right answer.
Hope this helps!
Two linear equation has their solutions on the points where they intersect each other.
The solution of the given system of equations is:
x = 2, y = 3.
How to determine the solution of system of linear equations graphically?Each linear equation represents a straight line.
If both the given lines intersect at one point, then that point's coordinate is the solution of the given system of the equations.
If both the given lines are parallel, then there is no intersection and thus no solution.
If both the lines are coincident(that is, lying over each other fully), then there are infinite points of intersection, as they touch each other on infinite points, and thus infinite solutions to the given system of equations exist.
Using method of substitution to solve the system of equations:[tex]y = 3x-3\\ x+y = 5 [/tex]
Substituting the value of y from first equation in the second equation, we get:
[tex]x + y = 5\\ x + (3x-3) = 5\\ x+3x = 5+3\\ 4x = 8 \\ x = 2\\ [/tex]
Thus, putting this value of x in first equation, we get:
[tex]y = 3x - 3\\ y = 3 \times 2 - 3\\ y = 6-3\\ y = 3[/tex]
Thus, the system has one solution and it is x = 2, y = 3.
Using graphing, we can see that point of intersection is (x,y) = (2,3)

a)Estimate how much money will she need altogher to purchase the computers?
Susana plans to sell each raffle ticket for £1.89.
b) Estimate how much tickets will she need to sell in order to buy all of the computers?
On Thursday, the day before the raffle, Susana had sold 4176 tickets.
c) Estimate how many more tickets she will need to sell in order to buy all of the computers
Answer:
Each computer costs £279.
37 computers will be needed.
a)Estimate how much money will she need altogher to purchase the computers?
£279 · 37 = £10,323
b) Estimate how much tickets will she need to sell in order to buy all of the computers? Susana plans to sell each raffle ticket for £1.89.
£10,323/£1.89 = 5461.905 tickets.
c) On Thursday, the day before the raffle, Susana had sold 4176 tickets. Estimate how many more tickets she will need to sell in order to buy all of the computers.

Alexa took a test and lost 3 points for each of the 7 questions she got wrong. She earned an additional 5 points for answering a bonus question correctly. How many points did Alexa receive or lose overall?
Answer:
Alexa lost 16 points overall
Step-by-step explanation:
To determine whether Alexa had a net receipt or loss of points, we will fine the total points received or lost, and find the difference:
points lost:
3 point for each of the 7 questions she answered wrong
lost point = 3 × 7 - 21 points
Points received:
5 points for answering a bonus question
point received = 5 point
The points lost (21) is greater than the points received (5), hence, there was a net loss. The net loss is calculated as follows:
points lost - points received
= 21 - 5 = 16
∴ Alexa lost 16 points overall

Determine if the lines are parallel, perpendicular, or neither.
3y = -2x + 18 and 6x + 9y = 18
Parallel
Perpendicular
Neither
Answer:
parallel
Step-by-step explanation:
1st step get the equations in y=mx+b
3y = -2x + 18
(÷ each side by 3)
y = -2/3x + 6
6x + 9y = 18
(subract 6x to get it to the other side)
9y = -6x + 18
(÷ both sides by 9)
y = -6/9x + 2
(simplify -6/9)
y = -2/3x +2
2nd step look at the equations
y = -2/3x + 6 and y = -2/3x +2
The lines are at different places and will never touch, having same slope theres never a possibility they would look something like this \\

What is the argument of z = 1/16 - square root of 3/16 i?
Answer:
A
Step-by-step explanation:
Edg2020
The value of the argument of z is -π/3.
What is the argument of z?The angle that the line from Ф, z to the origin creates with the positive direction of the real axis is known as the argument of z is Ф, and it is variously represented by the symbols arg ( z ), (z) or Ф. Because it is an argument of z is Ф, then 2 nπ + Ф is likewise a valid argument, the argument of z can take on any number of conceivable values.
We define a singular value known as the major argument of z to be more precise.
Given z = 1/16 - √3/16i
equation of z is x + iy
here x = 1/16 and y = -√3/16
to find the angle,
tanФ = y/x
tanФ = (-√3/16)/(1/16)
tanФ = -√3
Ф = tan⁻¹(-√3)
Ф = -π/3
Hence arguement of z is -π/3.
