Answer:
x = 2
Step-by-step explanation:
Note that the coordinates (2, 3) and (2, 5) both have the same x- coordinate.
This indicates that the points lie on a vertical line parallel to the y- axis.
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through.
In this case the x- coordinate is 2, hence the equation of the line is
x = 2
Fred the clown can create 20 balloon animals every 15 minutes. How many balloon animals can he create in 6 minutes?

6min = ????? = 20 multipyed by 6=
120 hope this helps:)
Answer: He can create 8 balloon animals in 6 minutes.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Fred the clown can create 20 balloon animals every 15 minutes.So, first we have to find the number of balloon animals he can create per minute by dividing the number of balloon animals created in 15 minutes (20) by the number of minutes (15).
Mathematically speaking:
20/15 = 1.3333 balloon animals per minute
Now we multiply the value obtained by 6:
1.333333 x 6 = 8 balloon animals (rounded)
What is the factored form of x^12y^18+1?
Answer:
[tex](x^{4}y^{6}+1)(x^{8}y^{12}-x^{4}y^{6}+1)[/tex].
Step-by-step explanation:
We want to expand: [tex]x^{12}y^{18}+1[/tex].
We can rewrite this as the sum of two cubes.
[tex](x^{4})^3(y^{6})^3+1=(x^{4}y^{6})^3+1^3[/tex].
Recall and use the sum of cubes identity: [tex]a^3+b^3=(a+b)(a^2-ab+b^2)[/tex]
By comparing our newly rewritten expression to this identity, we have [tex]a=x^4y^6[/tex] and [tex]b=1[/tex].
We substitute into the identity to get:
[tex](x^{4}y^{6})^3+1^3=[x^{4}y^{6}+1][(x^{4}y^{6})^2-(x^{4}y^{6})(1)+1^2][/tex].
We now use this rule of exponents :[tex](a^m)^n=a^{mn}[/tex] to get;
[tex](x^{4}y^{6}+1)(x^{8}y^{12}-x^{4}y^{6}+1)[/tex].
State the various transformations applied to the base function ƒ(x) = x^2 to obtain a graph of the function g(x) = −2[(x − 1)^2 + 3].
(A) A reflection about the x-axis, a vertical stretch by a factor of 2, a horizontal shift of 2 units to the right, and a vertical shift downward of 6 units.
(B) A reflection about the x-axis, a vertical stretch by a factor of 2, a horizontal shift of 1 unit to the right, and a vertical shift downward of 6 units.
(C) A reflection about the y-axis, a vertical stretch by a factor of 2, a horizontal shift of 1 unit to the right, and a vertical shift downward of 6 units.
(D) A reflection about the y-axis, a vertical stretch by a factor of 2, a horizontal shift of 2 units to the right, and a vertical shift downward of 6 units.
Answer: Option B
A reflection about the x-axis, a vertical stretch by a factor of 2, a horizontal shift of 1 unit to the right, and a vertical shift downward of 6 units.
Step-by-step explanation:
If the graph of the function [tex]g(x)=cf(h-h) +b[/tex] represents the transformations made to the graph of [tex]y= f(x)[/tex] then, by definition:
If [tex]0 <c <1[/tex] then the graph is compressed vertically by a factor c.
If [tex]|c| > 1[/tex] then the graph is stretched vertically by a factor c
If [tex]c <0[/tex] then the graph is reflected on the x axis.
If [tex]b> 0[/tex] the graph moves vertically upwards b units.
If [tex]b <0[/tex] the graph moves vertically down b units
If [tex]h> 0[/tex] then the graph of f(x) moves horizontally h units to the left
If [tex]h <0[/tex] then the graph of f(x) moves horizontally h units to the right
In this problem we have the function [tex]g(x) = -2((x - 1)^2 + 3)[/tex] and our parent function is [tex]f(x) = x^2[/tex]
therefore it is true that [tex]c =-2<0[/tex] and [tex]b =-6 <0[/tex] and [tex]h=-1<0[/tex]
Therefore the graph is reflected on the x axis, stretched vertically by a factor 2. The graph of f(x) moves horizontally 1 units to the right and shift downward of 6 units.
The answer is (B) A reflection about the x-axis, a vertical stretch by a factor of 2, a horizontal shift of 1 unit to the right, and a vertical shift downward of 6 units.
Final answer:
The correct transformations from f(x) = x² to g(x) = −2[(x − 1)² + 3] are a reflection about the x-axis, a vertical stretch by 2, a horizontal shift 1 unit to the right, and a vertical shift 3 units upwards, which is option (B) in the list provided.
Explanation:
The function g(x) = −2[(x − 1)² + 3] has undergone several transformations from the base function f(x) = x^2. These transformations include a reflection about the x-axis due to the negative sign in front of the equation, indicating that a flip has happened vertically. A vertical stretch by a factor of 2 is also evident from the coefficient 2 before the parenthesis.
The term (x - 1) inside the parenthesis indicates a horizontal shift of 1 unit to the right since we subtract from x to move the graph to the right. Lastly, the +3 at the end of the equation signifies a vertical shift of 3 units upwards, which is a change in the y-value of every point on the graph.
Therefore, the correct sequence of transformations to obtain g(x) from f(x) is: a reflection about the x-axis, a vertical stretch by a factor of 2, a horizontal shift of 1 unit to the right, and a vertical shift of 3 units upwards, which corresponds to option (B) provided by the student.
for f(x) equal 3x+1 and g(x) equal x-6 find (f - g) (x)
Answer:
2x + 7
Step-by-step explanation:

what is the inverse of f(x) = -5x-4
Answer:
[tex]\displaystyle f^{-1}(x) = -\frac{1}{5}x - \frac{4}{5}[/tex].
Step-by-step explanation:
The question has provided an expression for the function [tex]f(x)[/tex] and is asking for its inverse, [tex]f^{-1}(x)[/tex].
Based on the definition of inverse functions,
[tex]f(f^{-1}(x)) = x[/tex].
Let [tex]y = f^{-1}(x)[/tex].
[tex]f(y) = x[/tex].
[tex]-5 y - 4= x[/tex].
Solve this equation for [tex]f^{-1}(x) = y[/tex]:
[tex]-5y = x +4[/tex].
[tex]\displaystyle y = (-\frac{1}{5})\cdot (x + 4) = -\frac{x}{5} -\frac{4}{5}[/tex].
However, [tex]f^{-1}(x)=y[/tex] As a result,
[tex]\displaystyle f^{-1}(x) = -\frac{x}{5} -\frac{4}{5}[/tex].
Answer:
[tex]\large\boxed{f^{-1}(x)=-\dfrac{x+4}{5}}[/tex]
Step-by-step explanation:
[tex]f(x)=-5x-4\to y=-5x-4\\\\\text{Exchange x to y and vice versa:}\\\\x=-5y-4\\\\\text{Solve for}\ y:\\\\-5y-4=x\qquad\text{add 4 to both sides}\\\\-5y=x+4\qquad\text{divide both sides by (-5)}\\\\\dfrac{-5y}{-5}=\dfrac{x+4}{-5}\\\\y=-\dfrac{x+4}{5}[/tex]

What is the value of x in the equation −x = 4 − 3x + 6?
5
10
−5
−10
−x = 4 − 3x + 6
Move the -3x to the other side and simplify 4+6.
2x= 10
Divide both sides by 2
x=5.
Answer: First option.
Step-by-step explanation:
Given the equation [tex]-x = 4- 3x + 6[/tex], you need to solve for the variable "x" to find its value.
Add the like terms on the right side of the equation:
[tex]-x = 10-3x [/tex]
Now you need to subtract 10 from both sides of the equation:
[tex]-x-10 = 10- 3x -10[/tex]
[tex]-x-10 =- 3x[/tex]
The next step is to add "x" to both sides of the equation:
[tex]-x-10+x = - 3x +x[/tex]
[tex]-10 = - 2x[/tex]
And finally, divide both side by -2:
[tex]\frac{-10}{-2}=\frac{-2x}{-2}\\\\x=5[/tex]
What is 726,034 rounded to the nearest ten thousand
Answer:730000
Step-by-step explanation:
Follow below steps;
To round the number 726,034 to the nearest ten thousand, we must look at the thousands digit, which is 2. Since 2 is less than 5, we do not round up, and thus, leave the ten thousands place as it is.
The number 726,034 rounded to the nearest ten thousand is 720,000. We can see that the thousand's digit is less than 5, so we round down. This process aligns with the rounding rule stating that if the number you are rounding is followed by 0, 1, 2, 3, or 4, you round the number down.

A company makes glass lawn ornaments with a radius of 9 inches. The glass to make the balls costs the company $0.03 per square inch. To the nearest cent, how much does the company pay for the glass to create one ornament?
Answer:
$7.63
Step-by-step explanation:
We are given:
r=9 icnhes
We have to find the area of the circular ornament first. The formula for area of circle is:
Area= πr^2
Putting the value of r
Area=3.14*(9)^2
=3.14*81
=254.34 Square inches
As the company pays $0.03 for 1 square inch, for 254.34 square inch the company will have to pay:
=254.34*0.03
=$7.6302
Rounding off to the nearest cent
The cost for one ornament = $7.63
Answer:

What is the ordered pair of M after point M (5,6) is rotated 90 clockwise
Final answer:
The ordered pair of M after rotating 90 degrees clockwise is (-6,5).
Explanation:
When a point undergoes a 90-degree clockwise rotation around the origin, a distinct transformation occurs. Specifically, the x-coordinate of the original point becomes the negative value of its original y-coordinate, and the y-coordinate takes on the positive value of the original x-coordinate. This geometric operation is fundamental in transforming coordinates.
Taking point M(5,6) as an example, after the 90-degree clockwise rotation, the new coordinates manifest as (-6,5). This rotation plays a crucial role in various mathematical and geometric applications, contributing to the understanding of spatial transformations and coordinate systems.
choose all of the perfect squares 196 256 390 484 564
Answer:
{196, 256, 484}
Step-by-step explanation:
14² = 196;
16² = 256;
19² = 361; 390 lies between 361 and 400, and is thus NOT a perfect square;
20² = 400;
22² = 484
564 lies between the two perfect squares 23² and 24², but is itself NOT a perfect square.
Thus, the perfect squares are {196, 256, 484}
The perfect squares out of the numbers 196, 256, 390, 484, 564 are 196, 256, and 484. A perfect square is a number that can be expressed as an integer multiplied by itself.

(Factorise) 3m(Square) - 16mn - 12n (Square)
Answer:
(m - 6n)(3m + 2n)
Step-by-step explanation:
Given
3m² - 16mn - 12n²
Consider the factors of the product of the coefficient of the m² term and the n² term which sum to give the coefficient of the mn term
product = 3 × - 12 = - 36 and sum = - 16
The factors are - 18 and + 2
Use these factors to split the mn term
3m² - 18mn + 2mn - 12n² ( factor the first/second and third/fourth terms )
= 3m(m - 6n) + 2n(m - 6n) ← factor out (m - 6n) from each term
= (m - 6n)(3m + 2n)
Find three consecutive even integers whose sum is −24
For this case we have that the sum of 3 consecutive integers is 24, if we represent by means of an equation we have:
[tex]x + (x + 2) + (x + 4) = - 24\\x + x + 2 + x + 4 = -24\\3x + 6 = -24\\3x = -24-6\\x = \frac {-30} {3}\\x = -10[/tex]
Thus, the three consecutive numbers are:
[tex]x = -10\\x = -10 + 2= -8\\x = -10 + 4 = -6[/tex]
Answer:
-10,-8,-6
Answer: [tex]-10,-8,-6[/tex]
Step-by-step explanation:
Let be:
[tex]x[/tex], [tex]x+2[/tex] and [tex]x+4[/tex] the three consecutive even integers whose sum is -24
Then, we can write this expression:
[tex]x+(x+2)+(x+4)=-24[/tex]
Now, we must solve for "x":
[tex]3x+6=-24\\\\3x=-24-6\\\\3x=-30\\\\x=\frac{-30}{3}\\\\x=-10[/tex]
Then you get that the others integers are:
[tex]x+2=-10+2=-8[/tex]
[tex]x+4=-10+4=-6[/tex]
Therefore, the three consecutive even integers whose sum is -24 are:
[tex]-10,-8,-6[/tex]
