Graph the system of equations below on a piece of paper. What is the solution?
y = x – 1
y = 3x + 1

A. (2, 1)

B. (1, –2)

C. (–1, –1)

D. (–1, –2)
Answer:
Option D is correct
Solution = (-1, -2)
Step-by-step explanation:
Given the equation:
y = x – 1 ....[1]
y = 3x + 1 ....[2]
Equate equation [1] and [2] to solve for x.
[tex]x-1=3x+1[/tex]
Subtract x from both sides we have;
[tex]-1=2x+1[/tex]
Subtract 1 from both sides we have;
[tex]-2=2x[/tex]
Divide both sides by 2 we have;
x = -1
Substitute the value of x = -1 in [1] we have;
y=-1-1 = -2
Graphically:
Graph the system of equations as shown below.
The intersection point of these lines is the solution for the given system of equation
⇒ (-1, -2)
Therefore, the solution for the given system of equation is, (-1, -2)

The number of cases of a new disease can be modeled by the quadratic regression equation y = –2x2 + 36x + 6, where x represents the year.
Which is the best prediction for the number of new cases in year 15?
A. 194
B. 96
C. 328
D. 614
Answer: B 96
Step-by-step explanation:
By evaluating the function in x = 15, we will see that in the year 15 there will be 96 cases.
Which is the best prediction for the number of new cases in year 15?
The function that predicts the number of cases in the year x is given by:
[tex]y = -2x^2 + 36x + 6[/tex]
So we just need to evaluate that function in x = 15, this means replacing x by 15.
[tex]y = -2*15^2 + 36*15 + 6 = 96[/tex]
So we can expect that in the year 15, there will be around 96 cases. Then the correct option is B.

To transport 228 people to an island island ferry make six different trips on each trip the ferry carries the same number of people how many people does the ferry transport on each trip
Answer:
38 people
Step-by-step explanation:
Given: To transport [tex]228[/tex] people to an island island ferry make six different trips on each trip the ferry carries the same number of people.
To Find: how many people does the ferry transport on each trip.
Solution:
Total number of people to be transported [tex]=228[/tex]
Total number of trips made by island ferry [tex]=6[/tex]
As ferry carries same number of people in each trip
number of people ferry transport in each ferry [tex]=\frac{\text{total number of people to be transported}}{\text{total number of ferries}}[/tex]
putting values,
[tex]=\frac{228}{6}[/tex]
[tex]38[/tex]
Hence number of people ferry transport in each island ferry is [tex]38[/tex].

To fill in the table using the function rule y = -4x + 2, substitute the given x-values into the equation and solve for y.
To fill in the table using the function rule y = -4x + 2, substitute the given x-values into the equation and solve for y.
For x = -1, substitute x = -1 into the equation: y = -4(-1) + 2
For x = 0, substitute x = 0 into the equation: y = -4(0) + 2
For x = 1, substitute x = 1 into the equation: y = -4(1) + 2
For x = 2, substitute x = 2 into the equation: y = -4(2) + 2
By evaluating the expressions, you will obtain the corresponding y-values for each x-value.

a graduated cylinder is filled to 41.5 ml with water and a piece of granite is placed in the cylinder displacing the level to 47.6 ml what is the volume of the granite piece in cubic centimeters?
The volume of the piece of granite is 6.1 cubic cm if the graduated cylinder is filled to 41.5 ml with water and a piece of granite is placed in the cylinder, displacing the level to 47.6 ml.
What is volume?
It is defined as a three-dimensional space enclosed by an object or thing.
We have:
Volume of the water filled in the cylinder = 41.5 ml
Volume after placing the piece of granite = 47.6 ml
The volume of the piece of granite = 47.6 - 41.5 = 6.1 ml
As we know 1 ml = 1 cm³
The volume of the piece of granite = 6.1 cubic cm
Thus, the volume of the piece of granite is 6.1 cubic cm if the graduated cylinder is filled to 41.5 ml with water and a piece of granite is placed in the cylinder displacing the level to 47.6 ml.

At a certain college, the probability that a student attends full-time is 0.320 and the probability that the student attends part-time is 0.680. At the same college, the probability that a student receives financial aid is 0.570 while the probability that a student does not receive financial aid is 0.430. If a student is randomly selected, what is the probability that the student attends full-time and does not receive financial aid?
the probability that a randomly selected student attends full-time and does not receive financial aid is ( 0.1376 ), or ( 13.76% ).
To find the probability that a student attends full-time and does not receive financial aid, we can use the multiplication rule for independent events.
Given:
- Probability of attending full-time: [tex]\( P(\text{full-time}) = 0.320 \)[/tex]
- Probability of not receiving financial aid:[tex]\( P(\text{no financial aid}) = 0.430 \)[/tex]
By the multiplication rule, the probability of both events occurring is the product of their individual probabilities:
[tex]\[ P(\text{full-time and no financial aid}) = P(\text{full-time}) \times P(\text{no financial aid}) \][/tex]
[tex]\[ = 0.320 \times 0.430 \][/tex]
[tex]\[ = 0.1376 \][/tex]
Therefore, the probability that a randomly selected student attends full-time and does not receive financial aid is ( 0.1376 ), or ( 13.76% ).

The perimeter of a church window is 80 inches. If the window is in the shape of a square.what is the length of each side of the window?
The length of each side of the church window is 20 inches.
Explanation:To find the length of each side, we need to determine the perimeter of the square. The perimeter is the sum of all four sides of the square. In this case, it is given that the perimeter is 80 inches. Since all sides of a square are equal in length, we can divide the perimeter by 4 to find the length of each side. So, each side of the church window will be 80 inches divided by 4, which is 20 inches.
