Which statement accurately explains whether a reflection over the Y axis and a 270° counterclockwise rotation would map figure ACB onto itself?
Answers
When you reflect point C over (3,4) -> (-3,4) rotate 270 counter clockwise (-3,4) -> (4,3)
Neither the reflection over the y-axis nor the 270° counterclockwise rotation would map figure ACB onto itself.
Explanation:To determine whether a reflection over the y-axis and a 270° counterclockwise rotation would map figure ACB onto itself, we need to analyze the effects of these transformations.
A reflection over the y-axis would change the x-coordinates of the points, but not the y-coordinates. So, figure ACB would not be mapped onto itself after a reflection over the y-axis.A 270° counterclockwise rotation would change the position of the points by rotating them around the origin. After a 270° counterclockwise rotation, figure ACB would not be mapped onto itself as the shape and position of the points would change.Therefore, neither the reflection over the y-axis nor the 270° counterclockwise rotation would map figure ACB onto itself.

Rearrange x=3g+2 to make g the suject
please explain this to me well
Answers
Answer:
(x-2)/3 = g
Step-by-step explanation:
First you move the 2 over to the same side as the x by subtracting it on both side, because you are trying to make the g "alone". Then you move the 3 by doing the inverse, just like with the 2. Since you are multiplying 3 on one side to move to the other side you have to divide both sides by 3.
Answer:
g= (x-2)/3
Step-by-step explanation:
x=3g+2
Subtract 2 from each side
x-2=3g+2-2
x-2 = 3g
Divide each side by 3
(x-2)/3 = 3g/3
(x-2)/3 =g
g= (x-2)/3

If 132 people attend a concert and tickets for adults cost $3.25 while tickets for children cost $2.25 and total receipts for the concert was $364, how many of each went to the concert?
__adults
__children
Answers
Answer:
112 adults
20 children
Step-by-step explanation:
In order to solve this problem, we must create system of equations. By definition, system of equations are two equations which help you find unknown variables.
As for this problem, we need to set two variables for each type of person.
Let x represent adults
Let y represent children
We can break the question apart, and form equations based on the information given.
"tickets for adults cost $3.25 while tickets for children cost $2.25 and total receipts for the concert was $364"
$3.25x + $2.25y = $364
Now, we must form our second equation based on the information given.
"If 132 people attend a concert" "how many of each went to the concert"
x + y = 132
Solve for x, or the total number of adults
x = -y + 132
3.25(-y + 132)+ 2.25y = $364
Distribute 3.25
3.25 * -y = -3.25y
3.25 * 132 = 429
-3.25y + 429 = $364
Subtract 429 from both sides
364 - 429 = -65
-3.25y = -65
Now divide both sides by -3.25 to find the value of y.
y = 20
Therefore, 20 children attended the concert.
In order to find the total amount of adults who attended, subtract 20 from the total number of people that attended.
132 - 20 = 112
So, 112 adults attended as well as 20 children.
To find the number of adults and children who attended the concert, we can set up a system of equations and solve for the variables. Using the given information, we can determine that there were 67 adults and 65 children at the concert.
Explanation:To solve this problem, we can use a system of equations. Let's assume that the number of adults who attended the concert is 'a' and the number of children is 'c'. We can form two equations from the given information:
a + c = 132 (Equation 1)3.25a + 2.25c = 364 (Equation 2)Now, we can solve the system of equations to find the values of 'a' and 'c'.
Solving Equation 1 for 'a', we get a = 132 - c.
Substituting this value of 'a' into Equation 2, we get 3.25(132 - c) + 2.25c = 364.
Expanding and simplifying the equation gives us 429 - 3.25c + 2.25c = 364.
Combining like terms, we get -c = -65.
So, c = 65.
Substituting this value of 'c' into Equation 1, we get a + 65 = 132.
Solving for 'a', we get a = 67.
Therefore, there were 67 adults and 65 children at the concert.

By adding the system of equations and solving for x, then substantifying back into the first equation, we find that y in this system of equations is approximately 3.5556.
Explanation:To find the value of y in the given system of equations, you can add the two equations together. The first equation is x+3y=1 and the second equation is 2x – 3y = -30. Here are the steps:
Add the two equations: (x + 3y) + (2x - 3y).The y terms cancel out and you end up with 3x = -29.Divide both sides by 3 to solve for x: x = -29/3 which is about -9.6667.Substitute x = -9.6667 into the first equation: -9.6667 + 3y = 1.Isolate y by adding 9.6667 to both sides and then divide both sides by 3: y = (1 + 9.6667)/3. You will find that y = 3.5556 approx.
This value, 3.5556, is the value of y in the solution for the system of equations.

Step-by-step explanation:
When the object hits the ground, h = 0.
0 = -21.962x + 114.655
x = 5.2
From the table, the object landed at x = 4.6 seconds. So the line of best fit predicts a time 0.6 seconds greater than actual.
The original height is when x = 0.
h = -21.962(0) + 114.655
h = 114.7
So the line of best fit predicts the object was dropped from a height of 114.7 meters. This is higher than the actual 100 meters.
At x = 3.5:
h = -21.962(3.5) + 114.655
h = 37.8
So the line of best fit estimates the object reached a height of 37.8 meters after 3.5 seconds.
We know that at x = 0, h = 114.7. This is more than 4 meters from the actual initial height of 100 m.
Therefore, the answer must be A.
Answer:
A. According to the line of best fit, the object would have hit the ground 0.6 seconds later than the actual time the object hit the ground.

By definition the volume of a rectangular prism is the product of its length (l) by its width (w) by its height (h). This is:
[tex]V = lwh[/tex]
In this case we know that
l = [tex]8\ ^{1/2}[/tex] centimeters
l = [tex]8 + \frac{1}{2}=8.5[/tex] centimeters
w= [tex]9\ ^{1/3}[/tex] centimeters
w = [tex]9 + \frac{1}{3}=9.333[/tex] centimeters
h= [tex]12\ ^{2/5}[/tex] centimeters
h = [tex]12 + \frac{2}{5}=12.4[/tex] centimeters
Then
[tex]V = (8.5)(9.333)(12.4)\ cm^3[/tex]

Explain how to find the missing exponent given the base and the value
Answers
Answer:
To find the value of missing exponent, we have to split the number which is in other side of equal sign (which is not having power) as the multiple of base of the missing exponent.
On both sides, powers have the same base, so their exponents must be equal.
Step-by-step explanation:
Problem 1:Write the missing exponent:
25=5^x
Let x be the missing exponent.
To find the value missing exponent, we have to split the number which is in the left side as the multiple of the base of the missing exponent.
That is,
25=5*5 or 5^2
Now,
5^2=5^x
Powers have the same base so their exponent must be equal.
Hence the missing exponent is 2
