Answer: One unique solution.
Step-by-step explanation:
When we have a system of linear equations like:
y = a*x + b
y = c*x + d
We have 3 possibilities:
1) There is only one solution, this happens when in the graph, the lines intersect at only one point.
2) There is no solution, in this case, the lines never intersect, this would be the case of two parallel lines.
3) We have an infinite number of solutions, this happens when both lines intersect in an infinite number of points, and this can only happen when both lines are the same line.
In this case, we know that we have two lines and they intersect in only one point, (-1, 2)
Then we have only one solution, and the solution is (-1, 2)

Solve each of the following system of equations by substitution!!!
x-5y=-49
y=-2x+1
Answer:
x = -4, y = 9
or
(-4, 9)
Step-by-step explanation:
x - 5y = -49
y = -2x + 1
substitute y for -2x + 1
x - 5(-2x + 1) = -49
x + 10x - 5 = - 49
add 5 to both sides
x + 10x - 5 + 5 = - 49 + 5
x + 10x = -44
11x = -44
divide both sides by 11
11x/11 = -44/11
x = -4
substitute x for -4 in any of the original equations
y = -2x + 1
y = -2 * -4 + 1
y = 8 + 1
y = 9
Answer:
x = -4, y = 9 or (-4,9)

Solve each of the following system of equations by substitution!!!
x-5y=-49
y=-2x+1
Answer:
(-4,9)
Step-by-step explanation:
substitute the given value for y into the first equation
x-5(-2x+1)=-49
distribute
x+10x-5=-49
add like terms
11x-5=-49
add 5 to both sides
11x=-44
divide both sides by 11
x=-4
now plug x into into the second equation
y=-2(-4)+1
y=8+1
add like terms
y=9

What is the complex conjugate of the root x = 3i
Answer:
For example, the conjugate of 0 + √3 is 0 - √3, the conjugate of -√3 is √3, and the conjugate of 2 - 5√3 is 2 + 5√3.
Step-by-step explanation:
The complex conjugate of the root x = 3i will be x = -3i.
What is complex conjugate?The complex conjugate of a complex number is the number that has equal real and imaginary parts that are opposite in sign but equal in magnitude.
A given complex function is x = 3i
As we know that the complex conjugate function is one in which the imaginary part of the function becomes negative.
The complex conjugate function will be:-
x = -3i
Therefore the complex conjugate of the root x = 3i will be x = -3i.

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,077 was collected on the
sale of 1,201 tickets. How many of each type of ticket were sold?
The basketball game sold
adult tickets and
student tickets.
Answer:
Your problem will require you setting up 2 algebraic equations. First, you should.
Let A represent the number of adult tickets
Let S represent the number of student tickets
The first equation will be:
A+S = 1,215 tickets
The number of adult tickets plus the number of student tickets equals 1,215 tickets
The second equation will be:
5.00A+1.00S=$2,591
The price and number of adult tickets plus the price and number of student tickets equals $2,591.
I hope this has made the problem easier to understand. I hope you are able to solve the problem from here. If you can not solve the problem from here, I will be more than happy to further assist you.
Step-by-step explanation:
You have two unknowns, two variables, therefore you need to have at least two equations in this word problem in order to find a solution. Let's review the info you are given:
The price of an Adult ticket: $5
The price of a Student ticket: $1
The two variables are: the number of Adult tickets sold (you can use variable "A"), and the number of Student tickets sold (use variable "S").
The other info you are given is the total number of tickets sold: 1,215 tickets. Use this to make your first equation: the number of adult tickets plus the number of student tickets equals 1,215.
You are also told how much money was collected: $2,591. That means, $5 from every Adult ticket and $1 from every student ticket. We don't know how many of each ticket, but we assigned variables A and S to stand in for this unknown info. The money made from all the adult tickets would be the price of the adult ticket times how many adult tickets sold (5 times A), and the money made from all the student tickets would be the price of the student ticket times how many student tickets sold (1 times S). Use this to make your second equation, which says that all the money collected from all the tickets (5 times A in addition to 1 times S) is (=) 2,591.
Now you have two equations, each equation has two variables. To solve, go back to the easiest equation (the first one) and isolate one of the variables. By isolate I mean get it on one side of the equation by itself. Since in this case these variables are being added together, you have to do the opposite of addition, which is of course subtraction. To do this, you will have to subtract the other variable ON BOTH SIDES of the equation. So, say we want to isolate the variable A, we will subtract S from both sides. Well, S minus S is zero, so now A is isolated, meaning the left side of the equation is just A = ... Now you want to subtract the S on the other side. Remember that whatever you do to one side you must do to the other.
Now that you have your equation re-worked to show A = ..., you need to "plug it into" the second equation. What I mean is, you need to substitute instead of A, put in this equation. Then you will have one equation with one variable which you can solve! Remember the rules of equations, to do work in parenthesis first, the multiply or divide, then add or subtract. You will be able to solve for S.
Once you have found S (the number of student tickets sold), you can easily find A (the number of adult tickets sold) by going back to that first equation and subtracting your value of S from 1215.

If the points (2, 4), (5, k), and (8, 20) are on the same line, what is the value of k?
Answer:
k = 12
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (8, 20)
m = [tex]\frac{20-4}{8-2}[/tex] = [tex]\frac{16}{6}[/tex] = [tex]\frac{8}{3}[/tex]
Repeat using (5, k) as one of the points and equate to [tex]\frac{8}{3}[/tex]
(x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (5, k) , then
m = [tex]\frac{k-4}{5-2}[/tex] = [tex]\frac{k-4}{3}[/tex] = [tex]\frac{8}{3}[/tex] ( cross- multiply )
3(k - 4) = 24 ( divide both sides by 3 )
k - 4 = 8 ( add 4 to both sides )
k = 12

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 2, and the given zeros. -4,0,2,4
Answer:
A least degree polynomial, having rational coefficients and a leading coefficient of 2, with,-4, 0, 2, and 4 as the zeros of the polynomial is;
f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x
Step-by-step explanation:
The given parameters of the polynomial are;
The leading coefficient of the polynomial = 2
The zeros of the polynomial = -4, 0, 2, 4
We note that zeros of -4, and 4 gives a factor of the form, (x² - 4²)
For a zero of the polynomial equal to 0, one of the factors of the polynomial is equal to 'x'
To have a leading coefficient of 2, we can add '2' as a factor of the polynomial
Therefore, we can have the factors of the polynomial as follows;
(x² - 4²)·2·x×(x - 2) = 0
From the above equation, using a graphing calculator, we get the following possible polynomial;
(x² - 4²)·2·x×(x - 2) = 2·x⁴ - 4·x³ - 32·x² + 64·x = 0
Therefore, a polynomial, function of least degree that has rational coefficients, a leading coefficient of 2,and the zeros, -4, 0, 2, and 4 is f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x.
Two points in the (x, y) plane are a distance of 5 units apart. After a certain transformation is applied to both points, the two new points are 10 units apart. What was the transformation?
Answer:
translation
Step-by-step explanation:
Based on the information provided the type of transformation would have been a translation of one or both points. This means that either one or both points were moved. If only one point was moved it would have moved 5 units. If both were moved equally then they would have moved 2.5 units apart. Since we are not told the initial and end values of each point we cannot tell if the translation was a vertical or horizontal translation.

There are 25 students from the fifth-grade class collecting postage stamps.
Each student brought in 4 stamps, and their history teacher, Mr. Miller,
brought in 15 stamps.
Which expression could be used to find the total number of postage stamps
that were brought into class?
O A.
25 x (4 + 15)

B. (25 x 15) + 4
O C. (25 x 4) + 15
D.
(25 x 15)
- 4
Answer:
no C
(25×4)+15
because out of 25 students each students brought 4 stamps which means 25×4 and their teacher brought 15 which is added .
Answer:
C
Step-by-step explanation:
there are 25 students and they EACH brought 4. Each means you multiply. so we have 25x4. then Mr. Miller brought 15 more stamps so we need to add that to the equation. so we have (25x4) because that is separate from the 15.
(25x4)+15
