The graph the system of linear equations on a coordinate plane is added as an attachment and the solution is (2, 2)
How to graph the system of linear equations on a coordinate plane?A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
y=-1/2x+3 and y=2x-2
Rewrite the equations in the system of equations as follows:
So, we have the following representation
y = -1/2x + 3
y = 2x - 2
Next, we plot the graph of the system of equations
See attachment for the graph of the system of equations
The solution to the systemIn this case, the point of intersection of the equations represent the solution to the system
From the graph, the lines intersect at (2, 2)
This means that the solution to the system of equations is (2, 2)
Proof of the solutionRecall that
y = -1/2x + 3
y = 2x - 2
Solution = (2, 2)
So, we have
2 = -1/2 x 2 + 3 = 2 --- true
2 = 2 x 2 - 2 = 2 --- true

the positive integers x, y, and z are such that x is a factor of y and y is a factor of z. is z even? (1) xz is even. (2) y is even.
As asked in the question the value of xz and y will be even ,
xz is even and y is also even
given
X = factor of Y
Y = factor of Z
Therefore,
z= mnz = mnx , xz = even
because
either z even, so the answer is directly yes or x is even (or both) but if x is even and as then z= mnz = mnx must be even too (one of the multiples of z is even, so z is even too).
(2) y= even
because
as z=ny then as one of the multiples of z even then only z will be even

If y=x+2 we’re changed to y=x-1, how would the graph of the new function compare with the first one?
The graph of the new function compared to the first one will be shifted down.
Define vertical translation.Vertical translation describes the movement of a function graph upward or below. The function's form is preserved in this case. The graph moving or shifting along the y-axis is another name for it. Each point on the graph moves k units vertically during vertical translation, and the graph is said to have translated k units.
The two functions are
f(x) = x + 2
g(x) = x - 1
You can see that all you need to do to transform f into g is just take 3 off of it.
f(x) - 3 = (x+2) - 3
= x + 2 - 3
= x - 1
= g(x)
Every transformation, such as f(x) f(x) + k, now produces a vertical translation, which is translated upward if k > 0 and downward if k 0. The correct response is C since the function is translated three units down in our situation where k = -3.

an airline finds that 5% of the persons making reservations on a certain flight will not show up for the flight. if the airline sells 170 tickets for a flight that has only 165 seats, what is the probability that a seat will be available for every person holding a reservation and planning to fly? (round your answer to four decimal places.)
The probability that a seat will be available for every person holding a reservation and planning to fly s 0.9306.
What is probability?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Given: An airline finds that 5% of the persons making reservations on a certain flight will not show up for the flight.
The airline sells 170 tickets for a flight that has only 165 seats.
The proportion of reservations that do not show up for the flight
P = 5% = 0.05.
Number of tickets sold n = 170
Number of seats in the flight = 165
If at least 5 people do not show up then we have enough seats for every person.
P(X ≥ 5) = Σ (from 5 to 170)[tex]170C_x(0.05)^x(0.95)^1^7^0^-^x[/tex]
P(X ≥ 5) ≈ 0.9306

the combined perimeter of a circle and square is 16 cm. find the dimensions of the circle and square that produce a minimum total area.
the dimensions of the circle and square that produce a minimum total area are 1.12 and 2.24 respectively
given that
the combined perimeter of a circle and square is 16cm
let side length of the square is s
let radius of the circle with r
So, the perimeter (P) and the area (A) of the shape are:
P= 4s + 2[tex]\pi[/tex]r
A = [tex]s^{2}[/tex] + [tex]\pi[/tex][tex]r^{2}[/tex]
given that perimeter is 16
so, 4s +2[tex]\pi[/tex]r = 16
divide by 4
s +0.5[tex]\pi[/tex]r = 4
s = 4 - 0.5[tex]\pi[/tex]r
substitute s value in area
A = [tex](4-0.5\pi r)^{2}[/tex] + [tex]\pi[/tex]r
A = 16 - 4[tex]\pi[/tex]r +0.25[tex](\pi r)^{2}[/tex] +[tex]\pi[/tex][tex]r^{2}[/tex]
A =16 - 4[tex]\pi[/tex]r + (0.25 [tex]\pi ^{2}[/tex] + [tex]\pi[/tex])[tex]r^{2}[/tex]
differentiate with respect to r
A' = 0 - 4[tex]\pi[/tex] +2 (0.25 [tex]\pi ^{2}[/tex] + [tex]\pi[/tex])r
A' = - 4[tex]\pi[/tex] +2 (0.25 [tex]\pi ^{2}[/tex] + [tex]\pi[/tex])r
now A' =0
- 4[tex]\pi[/tex] +2 (0.25 [tex]\pi ^{2}[/tex] + [tex]\pi[/tex])r =0
2 (0.25 [tex]\pi ^{2}[/tex] + [tex]\pi[/tex])r = 4[tex]\pi[/tex]
divide both sides by 2
(0.25 [tex]\pi ^{2}[/tex] + [tex]\pi[/tex])r = 2[tex]\pi[/tex]
r = [tex]\frac{2\pi }{0.25\pi ^{2} +\pi }[/tex]
r = [tex]\frac{2\pi }{\pi (0.25\pi +1)}[/tex]
substitute [tex]\pi[/tex] =3.14
r = 2/(0.25(3.14)+1)
r = 1.12
substitute r value in s
s = 4 - 0.5 * 3.14 *1.12
s =2.24

Step-by-step explanation:
y as a function of x meaning:
Every x has a y, but the x value cannot repeat and every x has it's own y.
Example:
x: 1 2 3 4 5
y: 2 4 6 8 10
This is y as a function of x because the x values do not repeat and they each have a y value.
Example 2:
x:3 4 5 3 6
y: 1 2 3 4 5
This wrong because the 3 in the x value repeats twice which cause y not to be a function of x.
The reason why it wouldn't be B is because of -1
The reason why it wouldn't be C is because the y values repeat
The reason why it wouldn't be D is because all the x values are -7

Answer:
Step-by-step explanation:
Pros: Lower rates: Insurance rates are reduced for most consumers. ✓ Rates match risk: Higher-risk policyholders may pay a higher rate that accurately reflects their higher risk of loss – so lower-risk policyholders don't have to subsidize the cost of insurance for higher-risk policyholders.
Cons: HIGHER rates.
Insurance companies justify the use of insurance scores by citing studies showing a positive correlation between credit scores and insurance claims
A higher credit score decreases your insurance rate, often significantly, with almost every company and in most states. Getting a quote, however, does not affect your credit. Your credit score is a key part of determining the rate you pay for insurance.
