Which are the solutions of the quadratic equation? x2 = –5x – 3 –5, 0 5, 0
Answers
Note that if x=0, both sides of the equation are equal to 0.
So x=0 is a solution.
For [tex]x\neq0[/tex], then we can divide both sides of the equation by x, and we get x=-5.
Thus, the solution set is {0, -5}.
Remark: another way to solve the equation is to take -5x to the left hand side:
[tex]\displaystyle{x^2+5x=0[/tex],
then we factorize x as
[tex]\displaystyle{x(x+5)=0[/tex].
Thus we see that x is either 0, or -5.
The solutions of the quadratic equation x² = -5x - 3 are [tex]\( x = \frac{-5 - \sqrt{13}}{2} \)[/tex] and [tex]\( x = \frac{-5 + \sqrt{13}}{2} \)[/tex].
To find the solutions of the quadratic equation x² = -5x - 3, first we rearrange it to the standard form:
x² + 5x + 3 = 0
We solve this using the quadratic formula, which is given by:
x = [tex]\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
For our equation, a = 1, b = 5, and c = 3. Substituting these values in, we get:
x = [tex]\frac{-5 \pm \sqrt{5^2 - 4*1*3}}{2*1}[/tex]
x =[tex]\frac{-5 \pm \sqrt{25 - 12}}{2}\\[/tex]
x =[tex]\frac{-5 \pm \sqrt{13}}{2}[/tex]
Hence, the solutions are:
x = [tex]\frac{-5 - \sqrt{13}}{2}[/tex] and x = [tex]\frac{-5 + \sqrt{13}}{2}[/tex]

Answers
The equation of the line parallel to [tex]\(5x + 2y = 12\)[/tex] and passing through the point (-2, 4) is given as [tex]\(y = -\frac{5}{2}x - 1\).[/tex]
To find the equation of a line parallel to [tex]\(5x + 2y = 12\)[/tex] and passing through the point (-2, 4), we need to follow these steps:
1. Convert the given equation[tex]\(5x + 2y = 12\)[/tex] into slope-intercept form [tex]\(y = mx + b\).[/tex]
2. Determine the slope of the given line.
3. Use the slope and the given point to find the equation of the parallel line using the point-slope form.
4. Convert the equation into slope-intercept form if needed.
Let's start with step 1:
1. Convert [tex]\(5x + 2y = 12\)[/tex] into slope-intercept form [tex]\(y = mx + b\):[/tex]
Subtract [tex]\(5x\)[/tex] from both sides:
[tex]\[2y = -5x + 12\][/tex]
Divide both sides by 2:
[tex]\[y = -\frac{5}{2}x + 6\][/tex]
Now, we know that the slope of the given line is [tex]\(-\frac{5}{2}\)[/tex] . Since the line we're looking for is parallel to this line, it will have the same slope.
2. The slope [tex](\(m\))[/tex] of the parallel line is [tex]\(-\frac{5}{2}\).[/tex]
Next, we use the point-slope form[tex]\(y - y_1 = m(x - x_1)\),[/tex]where [tex]\((x_1, y_1)\)[/tex] is the given point (-2, 4) and [tex]\(m\)[/tex] is the slope.
3. Substitute the values into the point-slope form:
[tex]\[y - 4 = -\frac{5}{2}(x - (-2))\][/tex]
[tex]\[y - 4 = -\frac{5}{2}(x + 2)\][/tex]
Now, distribute[tex]\(-\frac{5}{2}\):[/tex]
[tex]\[y - 4 = -\frac{5}{2}x - 5\][/tex]
4. Convert to slope-intercept form:
Add 4 to both sides:
[tex]\[y = -\frac{5}{2}x - 5 + 4\][/tex]
[tex]\[y = -\frac{5}{2}x - 1\][/tex]
So, the equation of the line parallel to [tex]\(5x + 2y = 12\)[/tex] and passing through the point (-2, 4) is [tex]\(y = -\frac{5}{2}x - 1\).[/tex]

Let's begin with eliminating the y's in equations 1 and 3, then in equations 2 and 3:
[tex]-3x-4y-3z=-7 [/tex] times -1⇒ [tex]3x+4y+3z=7 [/tex]
[tex]5x-2y+5z=9[/tex] times 2⇒ [tex]10x-4y+10z=18[/tex]
ADD the two equations: 13x + 13z = 25
[tex]2x-6y+2z=3[/tex] times -1⇒[tex]-2x+6y-2z=-3[/tex]
[tex]5x-2y+5z=9[/tex] times 3⇒ [tex]15x-6y+15z=27[/tex]
ADD the two equations: 13x+13z=24
Subtract the two resulting equations and you get 0 = 1 which is false so there is no solution for the system.
Answer:
Given equations have no solution
Step-by-step explanation:
Given -
Three set of equations -
[tex]-3x-4y-3z=-7\\2x-6y+2z=3\\5x-2y+5z=9[/tex]
We will now equate "x" in the first equation in terms of "y" and "Z" and put it in second equation -
[tex]-3x-4y-3z=-7\\x = \frac{1}{3} (-4y -3z+7)\\\frac{2}{3}(-4y -3z+7) -6y+2z=3\\-8.667 y = -1.667\\y = 0.192\\[/tex]
We will substitute the value of y in the under given equation-
[tex]x = \frac{1}{3} (-4y -3z+7)\\x = \frac{1}{3} (-4*0.192 -3z+7)\\x= 2.077-z[/tex]
substituting the derived values in last equation, we get -
[tex]5x-2y+5z=9\\5(2.077-z)-2(0.192)+5z=9\\10.385-5z-0.384+5z=9\\0=-1[/tex]
Hence, the given equations have no solution
A scale model of a merry-go-round and the actual merry-go-round are similar.
a. How many times greater is the base area of the actual merry-go-round than the base area of the scale model? Explain. The ratio of the corresponding lengths is : 1. So, the ratio of the areas is : 1 and the base area of the actual merry-go-round is times greater than the base area of the scale model.
b. What is the base area of the actual merry-go-round in square feet? The base area of the actual merry-go-round is square feet.
Answers
The base area of the actual merry-go-round is the same as the model due to the 1:1 scale. Without further information, the actual base area of the merry-go round cannot be calculated.
Explanation:To understand this, we need to know a key principle of scale models. In a scale model, when the ratio of the lengths is 1:n, the ratio of the areas is square of that, or 1:n2. Hence, if the scale of models is 1:1 as given, the base area of the actual merry-go-round is equal to the base area of the scale model, meaning the ratio is also 1:1.
For part b, without the specific measurements of the base area of the scale model or the scale used, it is impossible to calculate the base area of the actual merry-go-round in square feet. We need one or the other to make this calculation.

Putting the terms together we get the final answer, which is 5x^3.
The expression [tex]10x^5/2x^2[/tex] simplifies to [tex]5x^3[/tex] by dividing the coefficients (10/2) to get 5 and subtracting the exponents (5 - 2) in [tex]x^5[/tex] and[tex]x^2[/tex]to get 3.
Explanation:To solve the given expression, [tex]10x^5/2x^2[/tex], you would first divide the coefficients and then deal with the bases (x) separately.
The coefficients (numbers without variables), 10 and 2, divide to give you: 10/2 = 5.
For the part that includes x, [tex]x^5/x^2[/tex], you subtract the lower exponent from the higher exponent because when you divide powers with the same base you subtract the exponents. So 5 - 2 = 3.
Thus, the final answer is: [tex]5x^3[/tex].

What is the area of the kitchen floor in this floor plan?
A-24 sq meters
B-28 sq meters
C-35 sq meters
D-42 sq meters
Answers
Answer: The correct option is (C) 35 sq. meters.
Step-by-step explanation: We are given to find the area of the kitchen floor in the floor plan shown in the figure.
From the figure, we see that
the kitchen is in the form of a rectangle with length 7 meters and breadth 5 meters.
We know that
the area of a rectangle with length l units and breadth b units is given by
[tex]A=l\times b.[/tex]
For the rectangular kitchen, we have
length, l = 7 meters
and
breadth, b = 5 meters.
Therefore, the area of the kitchen floor in the floor plan is given by
[tex]A=l\times b=7\times 5=35~\textup{sq. meters}.[/tex]
Thus, option (C) is CORRECT.

Answer: The correct option is
(C) if a = b and b = c, then a = c.

if x, y and z are three real numbers, then the transitive property of equality states that
if x = y and y = z, then x = z.

Amount of discount =
Discounted sales price =
Answers
The amount of discount is $1.095 and the discounted sales price is $9.855.
We need to calculate the amount of discount and then subtract it from the original sales price to find the discounted sales price.
First, we calculate the amount of discount. A 10% discount on an item selling for $10.95 means we need to find 10% of $10.95. To find 10% of a number, we can multiply the number by 0.10 (which is the decimal equivalent of 10%).
Amount of discount = 10% of $10.95
= 0.10 [tex]\times[/tex] $10.95
= $1.095
Now that we have the amount of discount, we can calculate the discounted sales price by subtracting the discount from the original sales price.
Discounted sales price = Original sales price - Amount of discount
= $10.95 - $1.095
= $9.855
