You are given the following system of equations: y:
- 13x + 85 and y = 15 + 4x . It is
known that this system of equations has two solutions. If the variable k represents the product of the two
×-values that satisfy the system, what is the value of k?
Answer:
70.
Step-by-step explanation:
1) to calculate the values of the 'x':
4x+15=x²-13x+85; ⇔ x²-17x+70=0; ⇔
x₁=7; x₂=10;
2) to calculate the required k:
k=x₁*x₂; k=7*10=70.

Transformation MATHS
anyone pls help me fond a solution to this ques
======================================================
Explanation:
Transformation V reflects over the line y = 0, which is the x axis. All points on the x axis have a y coordinate of zero. Examples are (1,0) and (2,0).
To reflect over the x axis, we flip the sign of the y coordinate. The x coordinate stays the same. Example: The point (1,5) moves to (1,-5).
In general the rule is [tex](x,y) \to (x,-y)[/tex]
---------------------
Transformation W rotates the point 90 degrees clockwise around the origin (0,0). The rotation rule is [tex](x,y) \to (y,-x)[/tex].
For example, the point (1,7) rotates to (7,-1) when doing a 90 degree clockwise rotation around the origin. We move from the northeast quadrant to the southeast quadrant.
As you can see, we swap the x and y coordinates. Then we do a sign flip on the new y coordinate.
----------------------
Transformation X combines the two previous transformations. We do V first then W next. The order is important (see the next section as to why).
We're given the point (g,h) where we don't know g nor h.
The x axis reflection rule has us get to (g, -h) because we simply flip the y coordinate from positive to negative, or vice versa.
Then applying transformation W has us get to (-h, -g) as the final answer.
----------------------
As stated earllier, the order of the transformations is important. Let's say we did W first and then V next.
Apply transformation W to go from (g,h) to (h,-g)Apply transformation V to go from (h,-g) to (h,g)The point (h,g) is different from (-h, -g) showing that the order does affect where the final point ends up.
However, some transformations can be composited together without worrying about the order. An example could be having a translation followed by another different translation.

Have you ever seen a photo online that did not seem to have the colors right? Perhaps the colors looked unnatural or not appropriate for the subject of the photo. Describe such a photo and what you think was wrong with it in terms of color. How did this photo with poor color values make you feel about the website it was on? How important do you think getting the color right is for images online?
Write three to five sentences that answer these questions. You should thoroughly explain every statement you make in your response. If possible, include a link to the photograph you are describing.
Answer:
Yes, I have before. The colors were pretty natural, but they didn't quite fit with the actual picture. It was a street with blue vintage contrast, and it had a rotting apple core. It was wrong because blue street didn't feel that normal and was an inaccurate portrayal because it didn't fit the apple core and all. The website actually was a website with "bad" photos, so I understood. I think it is very important to accurately convey meaning, tone, and much more.

Find X
Answer: 36
Step-by-step explanation:
In the figure below, m || n and t is a transversal line. If ∠7 = x +14 and ∠1 = 2x -8, what is ∠4?
∠4 and ∠1 are opposite angles, and since opposite angles are equal, ∠4 = 2x - 8
(if u need a specific number)
∠1 is corresponding to ∠5, and since corresponding angles are equal, ∠5 = 2x-8
∠7 is supplementary to ∠5, and since supplementary angles add up to 180, x + 14 + 2x - 8 = 180
-> 3x + 6 = 180
x = (180-6)/3 = 58.
Since ∠4 = 2x - 8 -> ∠4 = 2 x 58 - 8 = 108.

A rectangular box is 2 cm high , 4 cm wide and 6 cm deep.Mavis packs the box with cubes, each 2cm by2cm by 2cm,with no space left over. How many cubes does Mavis fit into the box?
Given -
A rectangular box is 2 cm high , 4 cm wide and 6 cm deep.i.e, length = 2cm, breadth = 4cm and height = 6cm
Mavis packs the box with cubes, each 2cm by 2cm by 2cm,with no space left over.i.e, side = 2cm
To find -
the number of cubes that can be fit into the rectangular box.Concept -
To find the number of cubes Mavis can fit into the rectangular box we are supposed to divide the volume of rectangular box by the volume of the cube. But before doing that we should know the formulas to find the volume of both the 3D shapes. i.e,
Volume of Rectangular Box = l × b × h
Volume cube = a³
where,
l = length b = breadthh = heighta = sideSolution -
[tex]\bf{Number\:of\: cubes=\frac{Volume\:of\: Rectangular\:Box}{Volume\:of\:cube}}[/tex]
[tex]\rightarrow\sf{Number\:of\: cubes=\frac{l\times b\times h}{a\times a\times a}}[/tex]
[tex]\rightarrow\sf{Number\:of\: cubes=\frac{2\times 4\times 6}{2\times 2\times 2}}[/tex]
[tex]\rightarrow\sf{Number\:of\: cubes=\frac{\cancel{2}\times \cancel{4}^2\times \cancel{6}^3}{\cancel{2}\times \cancel{2}\times \cancel{2}}}[/tex]
[tex]\rightarrow\sf{Number\:of\: cubes=2\times3}[/tex]
[tex]\rightarrow\mathbf{Number\:of\: cubes=6\:boxes}[/tex]
Hence, the number of cubes that can be fit into the rectangular box is 6 cubes.

fully explain why, in general, (a + b)^2 = a^2 +b^2.
No this is not correct identity
(a+b)²(a+b)(a+b)a(a+b)+b(a+b)a²+ab+ba+b²a²+2ab+b²Hence it's wrong
Answer:
Below!
Step-by-step explanation:
Let's simplify each side to determine if both sides are equal.
Left hand side of the equation:
Expression: (a + b)²This expression can be simplified using the rule (x + y)² = x² + 2(x)(y) + y².
⇒ a² + 2(a)(b) + b²When opening the parenthesis, we get;
⇒ a² + 2ab + b²This expression cannot be simplified further as there are no like terms in the expression obtained.
Right hand side of the equation:
Expression: a² + b²This expression cannot be simplified further as there are no like terms in the expression obtained.
Given equation:
(a + b)² = a² + b²This can be rewritten as;
a² + 2ab + b² = a² + b² (False)Therefore, it is impossible for a² + b² to be equivalent to a² + 2ab + b².

what is the area?
Answer:
28.26 ft²
Explanation:
[tex]\sf area \ of \ circle = \pi r^2[/tex]
Here given diameter: 6 ft
radius: d/2 = 6/2 = 3 ft
========
area of rug:
[tex]\dashrightarrow \ \pi (3)^2[/tex]
[tex]\dashrightarrow \ 9\pi[/tex]
[tex]\dashrightarrow \ 9(3.14)[/tex]
[tex]\dashrightarrow \ 28.26 \ ft^2[/tex]
Answer:
[tex]\underline{\underline{28.26 \ \text{feet}^{2}}}[/tex]
Step-by-step explanation:
Step-1) Determine the radius of the rug:
Given diameter: 6 feet
⇒ [tex]\text{Diameter = 2(Radius)}[/tex]⇒ [tex]\frac{\text{Diameter}}{2} = \frac{\text{Radius}}{2}[/tex]⇒ [tex]\frac{\text{Diameter}}{2} = \text{Radius}[/tex]Substitute the diameter to obtain the radius of the rug.
⇒ [tex]\frac{6}{2} = \text{Radius}[/tex]⇒ [tex]\text{3 feet = Radius}[/tex]Step-2) Find the area of the rug by substituting the radius in the formula:
Area of circular rug = πr²
= [tex]\pi (3)^{2}[/tex]
= [tex]\pi (3)(3)[/tex]
= [tex]\pi(9)[/tex]
Substituting π as 3.14 (Stated in comments):

Answer: 15
Step-by-step explanation:
first a price was decreased by 12% then it was discounted again by 5% what is the percent of the total discount. From RSM
x = original price or 100%
so if we discount "x" by 12%, that means the new price is 100% - 12% = 88%, let's see how much is 88% of "x"
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{88\% of x}}{\left( \cfrac{88}{100} \right)x}\implies 0.88x[/tex]
now if we grab that new price, or the new 100%, and discount it further by 5%, what's leftover is simply 95%, because we'll be taking off 5% off of it and thus left with 100% - 5% = 95%.
so what's 95% of 0.88x?
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{95\% of 0.88x}}{\left( \cfrac{95}{100} \right)0.88x}\implies 0.836x[/tex]
so the new discounted price is just 0.836x or 83.6% of our original "x".
from 100% originally to 83.6%, the difference is 16.4%, and that's the total discount.
Factor completely 9x3 + 36x2 - x - 4.
(3x + 4)(3x – 4)(x + 1)
(3x + 1)(3x - 1)(x + 4)
(9x2 - 1)(x + 4)
-
(3x + 1)(3x – 1)(x – 4)
-
The correct answer is: (3x + 1)(3x - 1)(x + 4)

Answer:
Y = 40
Step-by-step explanation:
First, find the slope-intercept of the table
Slope-intercept form: y = mx + b
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
(3, 1) and (6,2)
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-1}{6-3}\\\\m=\frac{1}{3}[/tex]
[tex]y=mx+b[/tex]
[tex]y=\frac{1}{3}x+b[/tex]
Find b using (6,2):
[tex]y=\frac{1}{3}x+b\\\\2=\frac{1}{3}(6)+b\\\\2=\frac{6}{3}+b\\\\2=2+b\\\\-2\ -2\\\\0=b[/tex]
[tex]y=\frac{1}{3}x+b== > y=\frac{1}{3}x+0== > y=\frac{1}{3}x[/tex]
[tex]y=\frac{1}{3}x[/tex]
What will be the value of Y when X = 120?
Substitute 120 for x into [tex]y=\frac{1}{3}x[/tex]
[tex]y=\frac{1}{3}x\\\\y=\frac{1}{3}(120)\\\\y=\frac{120}{3}\\\\y=40[/tex]
(120, 40)
Therefore, when X = 120, Y = 40
