Use the intersect method to solve the equation. x^2 - 3x = x^2 -1
The coordinate that represent the solution of the equation -
x² - 3x = x² - 1 is (0.333, -0.8889).
What is equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given is the following equation -
x² - 3x = x² - 1
In order to solve it using intersect method, we will plot the graphs of both functions and find the point of intersection of graphs of both the equations.
Assume -
f(x) = x² - 3x
g(x) = x² - 1
Now, the point of intersection of both the graphs will be the solution to the equation given by -
f(x) = g(x)
It can be seen from the graph that, both the graphs intersect at the coordinate (0.333, -0.8889). This coordinate will be the solution set of the equation -
f(x) = g(x)
Therefore, the coordinate that represent the solution of the equation -
x² - 3x = x² - 1 is (0.333, -0.8889).

The graph of the defined piece-wise function is sketched at the end of the answer.
What is a piecewise-defined function?A piecewise-defined function is a function that has different definitions, depending on the input of the function.
In the context of this problem, the function has three definitions, as follows:
To the left of x = -3. (x <= -3).Between x = -3 and x = 4. (-3 < x < 4).To the right of x = 4. (x >= 4)For the first definition, to the left of x = -3, the function assumes a constant value of 3, hence it is an horizontal line at y = 3.
For the second definition, between x = -3 and x = 4, the function is a increasing linear function, with intercept 1 and slope 2, due to the rule y = 2x + 1.
For the third definition, to the right of x = 4, the function assumes a constant value of -2, hence it is an horizontal line at y = -2.
With each of these definitions, the graph of the function is given at the end of the answer.

Answer: 1.33
Step-by-step explanation:
0.8 divided by 0.6= 1.33333333333
3 is in the hundredths place and 3 is in the thousandths place.
Since the digit in the thousandths place (3) is less than 5, the digit in the hundredths place (3) does not change.
The digits to the right of the hundredths place are dropped.
1.33333333 rounded to the nearest hundredth (two decimal places) = 1.33.
find the area of the circle. Use 3.14 for pie. Do not round your answer.
Answer: A = 452.16 ft²
Step-by-step explanation:
This gives us the formula to solve for the area.
A = πr²
The radius (r) is the same as the diameter divided by 2.
24 ft / 2 = 12 ft
We will input these given values and solve.
A = πr²
A = (3.14)(12)²
A = 452.16 ft²
Answer:
452.16 ft²
Step-by-step explanation:
To find the radius, you divide the diameter (24) by 2, which equals 12. The area of a circle formula is πr². To find area, you do 12² * 3.14. That equals 144 * 3.14, which equals 452.16.

Answer:
10x + 12y = 100
x + y = 9
Step-by-step explanation:
Define Variables:
Let x = the number of small boxes purchased
Let y = the number of large boxes purchased
Each small box has 10 granola bars, so small boxes have 10x granola bars.
Each large box has 12 granola bars, so large boxes have 12y granola bars. Therefore, the total number of granola bars 10x + 12y equals 100:
10x + 12y = 100
Since a total of 9 boxes were purchased, we know x + y must equal 9.
x + y = 9

The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x.
In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Reflect the given triangle over the y - axis [[3,6,3],[-3,3,3]]
By using a reflection over the y-axis, the coordinates of the image of the triangle are (- 3, - 3), (- 6, 3) and C'(x, y) = (- 3, 3).
How to determine the coordinates of the vertices of a triangle by rigid transformations
Rigid transformations are transformations applied on geometric loci such that the form of the construction is not altered. Reflections over the y-axis are examples of rigid transformations. In this problem we need to apply this kind of transformation on the three vertices of the triangle: A(x, y) = (3, - 3), B(x, y) = (6, 3), C(x, y) = (3, 3).
The reflection over the y-axis is described by the following formula:
P'(x, y) = P(x, y) + (- 2 · p, 0)
Where:
P(x, y) - Original pointP'(x, y) - Resulting pointp - x-Component of P(x, y).If we know that A(x, y) = (3, - 3), B(x, y) = (6, 3) and C(x, y) = (3, 3), then the image of the vertices of the triangle:
A'(x, y) = (3, - 3) + (- 6, 0)
A'(x, y) = (- 3, - 3)
B'(x, y) = (6, 3) + (- 12, 0)
B'(x, y) = (- 6, 3)
C'(x, y) = (3, 3) + (- 6, 0)
C'(x, y) = (- 3, 3)
Now we present the picture of the two triangles.
The coordinates of the image of the triangle are A'(x, y) = (- 3, - 3), B'(x, y) = (- 6, 3) and C'(x, y) = (- 3, 3).

Answer: A) x^2+y^2 B) x^3+y^3 C) a^2b^2c^2 D) c^2/d^2
Step-by-step explanation:
For A, you add all the powers. This is because the bases are the same. Any number or letter without a visible power on top most likely means that is has a power of 1. Because this is a multiplication question, you have to add the powers. (Example n*n = n^2 or n^3*n^7 = n^10)
This is same for B.
For C, you multiply abc by abc so it's a*a, b*b, c*c. This is because they are inside a bracket. Anything inside the bracket that has a power outside the bracket is multiplied by itself.
For D, you multiply c and d so it's c*c, d*d. This is the same as C.

Find the values of a,b and c that would make the statements true.
1) (ax+2)(5x+b)=10x^2+bx+c
The values of a, b and c are a = 2, b = -10 and c = -20
How to determine the values of the variables?The equation is given as
(ax + 2)(5x + b) = 10x^2 + bx + c
Open the brackets
So, we have
5ax^2 + 10x + abx + 2b = 10x^2 + bx + c
By comparing the above equation.
We have the following set of equations
5a = 10
10 + ab = b
2b = c
By solving the equations, we have
a = 2
Substitute a = 2 in 10 + ab = b
10 + 2b = b
So, we have
b = -10
Substitute b = -10 in 2b = c
2(-10) = c
Evaluate
c = -20
Hence, the values of the variables are a = 2, b = -10 and c = -20
