Answers
Answer:
B. 10
C. All real numbers.
Step-by-step explanation:
6 (2x-4) = 8(x + 2)
Distribute the numbers outside of the factors:
12x - 24 = 8x + 16
Subtract both sides by '8x'
12x - 8x - 24 = 8x - 8x + 16
4x - 24 = 16
Add '24' to both sides:
4x = 40
Divide both sides by 4:
x = 10. Therefore, B. 10 is the correct answer.
3(4p - 2) = -6(1 - 2p)
Distribute the numbers similarly to the example before:
12p - 6 = -6 + 12p
Subtract '12p' from both sides:
12p - 12p -6 = -6 + 12p - 12p
0 -6 = -6
Add '6' to both sides:
0 - 6 + 6 = -6 + 6
0 = 0
Therefore, the solution consists of all real numbers.

Multiply the following complex numbers:
(5+3i)(4+ 2i)
A. 14-22i
O B. 14+ 22i
O C. 26 - 22i
O D. 26 + 22i
Answers
Answer:
B, or 14 + 22i.
Step-by-step explanation:
When multiplying complex numbers, use the FOIL method.
Therefore:
(5 + 3i)(4 + 2i)
FOIL the equation:
5×4 + 5 × 2i + 3i × 4 + 3i × 2i
Simplify. Remember that i² = -1.
20 + 10i + 12i -6
Combine like terms:
14 + 22i
Therefore, the solution is B, or 14 + 22i.

Which value of x makes this inequality true?
X + 9 < 4x
Answers
We want to get out x's together on the right side of the inequality.
So, subtract x from both sides to get 9 < 3x.
Now divide both sides by 3 and we get 3 < x.
I personally like to have my variables on the left so we can move the 3 to the left and the x to the right but if we do that, we have to switch the inequality sign.
So we can rewrite this as x > 3.

A conic section is defined by the cross section of a plane and a double-napped cone. There are other special cases called degenerate conics, which are lines and points (occurs when the equation does not follow the usual pattern, however, these are not considered main conics). The main types of conics are: ellipses, hyperbolas, and parabolas.

Answers
Answer: Ramesh has 80,000 100Rs, 120,000 50Rs and 200,000 10Rs.
Step-by-step explanation:
From the question, the ratio of number of 100, 50 and 10Rs notes is 2:3:5respectively and the total cash with ramesh is 400000.
Total ratio = 2+3+5 = 10
100Rs = 2/10 × 400000
= 80,000
50Rs = 3/10 × 400000
= 120,000
10Rs = 5/10 × 400000
= 200,000
Ramesh has 80,000 100Rs, 120,000 50Rs and 200,000 10Rs.

=35x+
75/2
Answer:
see below
Step-by-step explanation:
y = 75+ 15x where x is the number of days and y is the cost
Let x = 1
y = 75+15(1)
y = 90 for one day
for x days
y = 75+15x
Is the relation {(1, 3), (–4, 0), (3, 1), (0, 4), (2, 3)} a function? Why or why not? Yes, the range value 3 corresponds to two domain values, 1 and 2. No, the range value 3 corresponds to two domain values, 1 and 2. No, there is no value in the domain that corresponds to more than one value of the range. Yes, there is no value in the domain that corresponds to more than one value of the range.
Answers
Answer:
The answer is D.
Step-by-step explanation:
The relation is indeed a function because of the reason as described by choice D.
A function is relation that maps a set of elements known as inputs to another set of elements known as the outputs, such that each input element is mapped to exactly one output element
The relationship between the given values is a function and, the correct option is; Yes, there is no value in the domain that corresponds to more than one value of the range
The reasons the selected option are correct is as follows:
The given ordered pair are presented in a tabular form as follows:
[tex]\begin{array}{|c|cc|}\mathbf{Domain \ (x)}&&\mathbf{Range \ (y)}\\1&&3\\-4&&0\\3&&1\\0&&4\\2&&3\end{array}\right][/tex]
In a function, each value in the domain corresponds with one element in the range. Therefore, if two elements in the domain corresponds to one element in the range, the relationship is not a function
Therefore;
[tex]\begin{array}{|c|cc|}\mathbf{ x}&&\mathbf{y}\\1&&1\\1&&2\\1&&3\\1&&4\\1&&5\end{array}\right] \ Is \ not \ a \ function[/tex]
[tex]\begin{array}{|c|cc|}\mathbf{Domain \ (x)}&&\mathbf{Range \ (y)}\\1&&3\\-4&&0\\3&&1\\0&&4\\2&&3\end{array}\right] \ Is \ a \ function[/tex]
In the table above, each element in the domain appear only once, and therefore, each element in the domain correspond or gives only one value in the range, while the element 3 in the range corresponds to 1, and 2 in the domain. However, the range are the output values of the function, and therefore, the data satisfies the relationship of a function
The correct option is; Yes, there is no value in the domain that corresponds to more than one value of the range

f(x)=(x-3)^2+5 plot the vertex and the axis of symmetry of this function.
Answers
Answer:
The vertex is located at (3,5)
The axis of symmetry is x = 3
The plot is in the image attached
Step-by-step explanation:
First we need to find the vertex of the quadratic function. We can find the x-coordinate of the vertex using the formula:
x_v = -b / 2a
Where 'a' and 'b' are coefficients of the quadratic equation in the model:
ax^2 + bx + c = 0
Then we need to expand the terms of f(x):
f(x) = (x-3)^2 + 5
f(x) = x^2 - 6x + 9 + 5
f(x) = x^2 - 6x + 14
So we have a = 1 and b = -6
Then the x-coordinate of the vertex is:
x_v = 6 / 2 = 3
We can use this value in f(x) to find the y-coordinate of the vertex:
f(x_v) = 3^2 - 6*3 + 14 = 5
So the vertex is located at (3,5)
The axis of symmetry is the vertical line traced in the vertex, so it is x = 3
The plot is in the image attached. The circle at (3,5) is the vertex, and the blue line is the axis of symmetry.

Write the equation for the linear function that goes through –3 on the y-axis and has a slope of 0.5.
y= ????
Answers
Answer: y = [tex]\frac{1}{2} x[/tex] - 3
Step-by-step explanation:
The equation for a line is in the form y = mx + b, where "m" is the slope and "b" is the y-intercept.Since the slope is 0.5 (which is [tex]\frac{1}{2}[/tex]), we can plug that value in for "m": y = [tex]\frac{1}{2} x[/tex] + bSince the line goes through -3 on the y-axis, that is the y-intercept. So, we can just plug in that value for "b": y = [tex]\frac{1}{2} x[/tex] - 3And there's your answer: y = [tex]\frac{1}{2} x[/tex]-3

Patty made a banner that has an area of 96 square inches. The length and width of the banner are whole numbers. The length is 6 times greater than the width. What are the dimensions of the banner?
Answers
Answer:
The length of the banner is 24 inches and its width is 4 inches.
Step-by-step explanation:
Let the length of the banner be L.
Let the width of the banner be W.
The length is 6 times greater than the width. This means that:
L = 6W
The area of the banner is:
A = L * W = 6W * W = [tex]6W^2[/tex]
The are of the banner is 96 square inches. This implies that:
[tex]6W^2[/tex] = 96
=> [tex]W^2[/tex] = 96 / 6 = 16
W = [tex]\sqrt{16}[/tex]
W = 4 inches
The length, L, will be:
L = 6 * 4 = 24 inches
The length of the banner is 24 inches and its width is 4 inches.
