A system of equations is a collection of related equations
The system of equations that can be used to solve [tex]12x^3 - 5x = 2x ^2 + x + 6[/tex] [tex]y = 2x ^2 + x + 6[/tex] and [tex]y= 12x^3 - 5x[/tex]
The equation is given as:
[tex]12x^3 - 5x = 2x ^2 + x + 6[/tex]
Split the above equation into 2, and set both equations to 0
[tex]12x^3 - 5x = 0[/tex]
[tex]2x ^2 + x + 6 = 0[/tex]
Replace the "0" with y, in both equations
[tex]12x^3 - 5x = y[/tex]
[tex]2x ^2 + x + 6 = y[/tex]
Rewrite the equations as:
[tex]y = 2x ^2 + x + 6[/tex]
[tex]y= 12x^3 - 5x[/tex]
Hence, [tex]y = 2x ^2 + x + 6[/tex] and [tex]y= 12x^3 - 5x[/tex] can be used to solve [tex]12x^3 - 5x = 2x ^2 + x + 6[/tex]

Kiyo is designing a rectangular garden with a 2-ft wide path all the way around it. The length of the garden is 3 times as long as the width. Kiyo models the area of his garden and the path with the equation f(x) = (x + 2)(3x + 2). Explain Kiyo’s error
Answer:
The correct equation that models the area if x(3x) or 3x² where x is the width of the pathStep-by-step explanation:
Area of a rectangle = Length *Width
Width of the rectangular garden W = 2ft
If the length of the garden is 3 times as long as the width, then length = 3 * width i.e W = 3L
Since Area of the path A = L* W
A = (3W)W
A = 3W²
If the width is the same as x then
Area f(x) = (3x)(x)
According to kyle, the area of his path f(x) = (x + 2)(3x + 2) which is wrong because of kyle addition of 2 to each of the value of the length and width respectively which kyle shouldn't have added any value to the dimension to the garden

Answer:
The liquid is a compound because it contains more than one substance.
Two objects that are the same shape but not the same size are?
Answer:
Similar
Step-by-step explanation:
Objects that have the same shape but not size are defined to be similar.
Objects with the same shape and size are defined as congruent.
Anything that is congruent is ALSO similar.
Answer:
SimilarStep-by-step explanation:
Two angles are congruent if they have the same measure. Two figures are similar if they have the same shape but not necessarily the same size. All of the figures below are congruent since they all have the same shape and size.
The side on a clip board appears to be a right triangle. The leg lengths are 2 millimeters and 2.1 millimeters and the hypotenuse is 2.9 millimeters. Is the side of the clip a right triangle?
Answer:
Yes, it is a right angle triangle
Step-by-step explanation:
Let leg lengths be y and z
Y = 2mm
Z = 2.1mm
Let x represent hypothenus
X = 2.9mm
To find out if it's a right angle triangle, we'll use pythagorean theorem since it's true for all right angle triangles I.e the square of the hypothenus is equal to the square of both sides(opposite and adjacent)
x² = y² + z²
x² = 2² + 2.1²
x² = 4 + 4.41
x² = 8.41
Take the square root of both sides
x = √(8.41)
x = 2.9mm
Therefore since the square of two other sides equal the square of the hypothenus, the side of the clip is a right angle triangle

Find the angle represented by x (rounded to the nearest tenth of a degree). A) 32.6° B) 36.4° C) 37.8° D) 38.7°
Answer:
The angle is 49.63°, approximately.Step-by-step explanation:
In the image attached, you can observe that the angle we need to find is an acute angle of a right triangle, where its hypothenuse is 21 units long and its opposite leg is 16 units long.
Having these elements, we can use the sine trigonometric reason to find the angle.
[tex]sin(x)=\frac{opposite \ leg}{hypothenuse} =\frac{16}{21}\\ x=sin^{-1}(\frac{16}{21} ) \approx 49.63\°[/tex]
Therefore, the angle is 49.63°, approximately.
solve this equation 5x+17= 42
Answer:
x = 5
Step-by-step explanation:
5x + 17 = 42
5x = 25
x = 5
Answer:
x = 5
Step-by-step explanation:
5x+17= 42
Subtract 17 from each side
5x+17-17= 42-17
5x = 25
Divide each side by 5
5x/5 = 25/5
x = 5

Answer:
5*14=70
Step-by-step explanation:
Divide 28 by 2 because it is the second on the number line and because Jonah folded 2 shirts in that time. You would get 14. You then get a speed of 1 shirt every 14 seconds. That means if you multiply 5 with 14, you'd get the number of seconds it'd take for Jonah to fold her clothes. Not a nice chore I must say. Pardon my english, and hope this helps :)

because..............
Using fraction, the sheets are a color other than red is 5.
What is fraction?Fraction is a "number are expressed as quotient, where numerator is divided by denominator".
According to the question,
Faith has 25 sheets of colored paper. She plans to make 15 of the cards out red paper.
[tex]\frac{15}{25}[/tex] = [tex]\frac{3}{5}[/tex]
5 - 3 =2
Fraction 5 parts of sheets is equal to 25, 3 parts of sheet is equal to 15.
5 = 25
2 = x
5 × 5 = 25
2 × 5 = 10
Hence, using fraction the number of sheets are a color other than red is 5.

You just bought ten trees and want to plant them in 5 rows with 4 trees in each row. How will you plant the trees?
Answer:
You can't you have to use 20 trees since 20 divided by 5 is 4.
So using 10 would make it 10 divided by 5 which is 2.
And the trees can't be halve so it's 20. 10 is impossible.

For what value of x the relation S: {(x2+3,4), (5,2)} is not a function?
Answer:
x = ±sqrt(2)
Step-by-step explanation:
It is not a function if the same input goes to 2 different outputs
x^2 +3 =5 would cause the same input to go to 2 different outputs
Subtract 3 from each side
x^2 +3-3 =5-3
x^2 = 2
Take the square root of each side
sqrt(x^2) = ±sqrt(2)
x = ±sqrt(2)
Answer:
x = sqrt(2), -sqrt(2)
Step-by-step explanation:
For a function, there cannot be multiple outputs for the same input, therefore x²+3 should not be 5
x² + 3 = 5
x² = 2
x = +/- sqrt(2)
