According to the graph, what is the solution (ordered pair) of this system of equations?
Answers
Answers:
(2, -3) and (3, -3)
==================================================
Work Shown:
Since f(x) = -3, we'll replace f(x) with -3 and solve for x
f(x) = x^2 - 5x + 3
-3 = x^2 - 5x + 3 .... f(x) replaced with -3
0 = x^2 - 5x + 3 + 3 ... adding 3 to both sides
0 = x^2 - 5x + 6
x^2 - 5x + 6 = 0
(x - 3)(x - 2) = 0 .... factor; you can also apply the quadratic formula
x-3=0 or x-2=0
x = 3 or x = 2
So that explains where that '2' comes from when they listed (2, ?)
-------------
To find what replaces the question mark, we will plug x = 2 into the function
f(x) = x^2 - 5x + 3
f(2) = 2^2 - 5(2) + 3
f(2) = 4 - 10 + 3
f(2) = -3
We could have skipped this portion and said that the solution is (2,-3) but plugging x = 2 into the function to get the output y = -3 helps confirm that x = 2 is one of the x solutions.
-------------
Let's do the same for x = 3
f(x) = x^2 - 5x + 3
f(3) = 3^2 - 5(3) + 3
f(3) = 9 - 15 + 3
f(3) = -3
We end up with the same output, so x = 3 is confirmed as well.
The graph below visually helps reinforce these confirmations. Each solution is an intersection between the two curves.

Simplifying each radical
[tex]\sqrt{27}[/tex]

Which of the following equations are equations of a direct variation? Choose all that apply.
(a) x=−2y
(b) x+2y=12
(c) 3x−2y=0
(d) 5x^2+y=0
(e) y =0.3x +1.6
(f) y−2=x
Answers
Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
y = x/-2 → y = -1/2x This is equivalent to multiplying x by -1/2, so this is an example of direct variation.(b) x + 2y = 12
2y = 12 - x y = 6 - 1/2x This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.(c) 3x - 2y = 0
-2y = -3x y = 3/2x This follows the format of y = kx, so it is an example of direct variation.(d) 5x² + y = 0
y = -5x²This is not in the form of y = kx, so it is NOT an example of direct variation.(e) y = 0.3x + 1.6
1.6 is being added to 0.3x, so it is NOT an example of direct variation.(f) y - 2 = x
y = x + 2 2 is being added to x, so it is NOT an example of direct variation.The following equations are examples of direct variation:
x = -2y 3x - 2y = 0Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
y = x/-2 → y = -1/2x
This is equivalent to multiplying x by -1/2, so this is an example of direct variation.
(b) x + 2y = 12
2y = 12 - x
y = 6 - 1/2x
This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.
(c) 3x - 2y = 0
-2y = -3x
y = 3/2x
This follows the format of y = kx, so it is an example of direct variation.
(d) 5x² + y = 0
y = -5x²
This is not in the form of y = kx, so it is NOT an example of direct variation.
(e) y = 0.3x + 1.6
1.6 is being added to 0.3x, so it is NOT an example of direct variation.
(f) y - 2 = x
y = x + 2
2 is being added to x, so it is NOT an example of direct variation.
The following equations are examples of direct variation:
x = -2y

21 = w^2 + 4w
C.
21 = w^2 – 4w
D.
21 = w^2 + 4
Answers
Answer:
D
Step-by-step explanation:
The equation to determine the length and width of the rug is 21 = w² + 4w.
What is Rectangle?A rectangle is a four sided figure with opposite sides are equal .
Area of a rectangle = Length x width
Given that A rectangular rug with an area of 21 square feet.
The rug is 4 feet longer than it is wide.
Let 'l " be the length of the rug and 'w' be the width of the rug
Length is 4 feet longer than its width
l = w + 4
Area is 21 square feet.
Area = l x w
21 = (w + 4)w
21 = w² + 4w
The equation to determine the length and width of the rug is 21 = w² + 4w.
So width is 3 ft
Length = w +4
length = 3+4= 7 feet
Thus Length of the rug is 7 feet
Length of rug = 7 feet
width of the rug = 4 feet

Answers
Answer: The next three terms =2.56, - 1.024 and 0.4096
Step-by-step explanation:
Common Ratio of a Geometric sequence, R is calculated as
=a2/a1 = -40/100=-0.4
or a3/a2=16/ -40 = -0.4
such that the next three terms are
5th term = -6.4 x -0.4=2.56
6th term= 2.56 x -0.4 =-1.024
7TH term= -1.024 x -0.4=0.4096
