The graph of which function has an axis of symmetry at x = 3?
The graph of y = 2(x - 3)² + 2 has an axis of symmetry at x = 3
The graph of which function has an axis of symmetry at x = 3?
From the question, we have the following parameters that can be used in our computation:
The quadratic functions
A quadratic function is represented as
y = a(x - h)² + k
Where,
The axis of symmetry is at x = h
Using the above as a guide, we have the following:
The graph of y = 2(x - 3)² + 2 has an axis of symmetry at x = 3
Question
The graph of which function has an axis of symmetry at x = 3?
y = 4(x + 3)²
y = 2(x - 3)² + 2
y = x² + 2
y = 2(x + 5)² + 2
A system of equations is shown.
x + y = 7
2x – y = – 1
What is the solution to the system of equations?
Final answer:
To solve the system of equations (x + y = 7 and 2x - y = -1), use the addition method to find that the solution is x = 2 and y = 5.
Explanation:
The question asks for the solution to the following system of equations:
x + y = 7
2x – y = – 1
To solve this system, we can use the method of addition (also known as elimination) to eliminate one of the variables. Here's how:
Add the two equations directly to eliminate variable y:
(x + y) + (2x - y) = 7 – 1
3x = 6
Therefore, x = 2.
Substitute the value of x into one of the original equations to find y:
2 + y = 7
Therefore, y = 5.
So, the solution to the system of equations is x = 2 and y = 5.
The solution to the system of equations is [tex]x = 2[/tex] and [tex]y = 5[/tex].
To solve the system of equations [tex]x + y = 7[/tex] and [tex]2x - y = -1[/tex], we can use a method called substitution or elimination. Let's use substitution for this case.
Start with the first equation:
[tex]x + y = 7[/tex]
Solve this equation for one of the variables, say [tex]y[/tex]:
[tex]y = 7 - x[/tex]
Substitute [tex]y = 7 - x[/tex] into the second equation:
[tex]2x - (7 - x) = -1[/tex]
Simplify and solve for [tex]x[/tex]:
[tex]2x - 7 + x = -1[/tex]
[tex]3x - 7 = -1[/tex]
[tex]3x = 6[/tex]
[tex]x = 2[/tex]
Substitute [tex]x = 2[/tex] back into the expression for [tex]y[/tex]:
[tex]y = 7 - 2[/tex]
[tex]y = 5[/tex]
This means that the point [tex](2, 5)[/tex] is where the two lines represented by these equations intersect. Therefore, the solution is [tex](2, 5)[/tex].
To ride your favorite roller coaster, you must be at least five feet tall but
less than seven feet tall. Let h represent any height that can ride the roller
coaster.
Answer:
5 ≤ h<7
Step-by-step explanation:
the rider has to be more than at least 5 feet tall, so h is greater than or equal to 5 (5 ≤ h), but they have to be less than 7 feet tall (h<7) so, therefore, we get 5 ≤ h<7

3 Maddie's little brother spilled ketchup on one of her homework problems.
Assuming that the number under the spill is greater than zero, fill in the bubble
to show what Maddie should be able to tell for sure about the answer, even
though she can't see the other number.
O The answer will be less than 3.
O The answer will be less than the ketchup-covered number.
O The answer will be a fraction.
O The answer will be greater than the ketchup-covered number.
b.Explain your answer. How do you know the statement you chose is true?
Final answer:
Maddie should be able to tell for sure that the answer will be greater than the ketchup-covered number.
Explanation:
Based on the information provided, Maddie should be able to tell for sure that the answer will be greater than the ketchup-covered number. We can make this determination by comparing the known quantity, which is '3', with the fact that the obscured number is greater than zero. As long as the missing number is positive, any amount added to '3' would result in a sum that is larger than '3'.
If the hidden number is greater than zero and we add it to '3', the result must logically be greater than '3'. This concept is grounded in the basic principles of arithmetic, where adding a positive number to another number increases the total. Therefore, regardless of what the ketchup-covered number is, provided it is more than zero, the sum will indeed be larger than the visible number '3'.
Rewrite the equation below so that it does not have fractions four -4/9 times equals two over three do not use decimals in your answer please help me I’ll give you 10 points
The equation is 36 - 4x = 6.
Solution:
To write the equation without fraction.
[tex]$4-\frac{4}{9} x=\frac{2}{3}[/tex]
[tex]$\frac{4}{1} -\frac{4}{9} x=\frac{2}{3}[/tex]
The denominators must be same to add/subtract the fractions.
LCM of 1, 9 and 3 = 9.
Multiply first term by [tex]\frac{9}{9}[/tex] and [tex]\frac{2}{3}[/tex] by [tex]\frac{3}{3}[/tex] to make the denominator same.
[tex]$\frac{4\times9}{1\times9} -\frac{4}{9} x=\frac{2\times3}{3\times3}[/tex]
[tex]$\frac{36}{9} -\frac{4}{9} x=\frac{6}{9}[/tex]
[tex]$\frac{36-4x}{9} =\frac{6}{9}[/tex]
Multiply by 9 on both sides.
[tex]$\frac{36-4x}{9}\times9 =\frac{6}{9}\times9[/tex]
Both 9 in the numerator and denominator get canceled.
36 - 4x = 6
This term does not have fraction.
Hence the equation is 36 - 4x = 6.

1). 8, 24, 72, 216.... ____, ______, _____,
Answer: 648, 1,944, and 5,832.
Step-by-step explanation: Begin by studying the pattern.
Here, notice that 8 × 3 is equal to 24.
24 × 3 is equa to 72.
72 × 3 is equal to 216.
Continuing the same pattern, 216 × 3 is equal to 648.
648 × 3 is equal to 1,944.
1,944 × 3 is equal to 5,832.
I have also attached in image below showing my work.
So the three missing terms in the pattern are 648, 1,944, and 5,832.

O g(x) = x + 6
Answer:
[tex]g(x) = x + 6[/tex]
Step-by-step explanation:
The parent function is given as:
[tex]f(x) = x + 8[/tex]
We want to find a new function that results after shifting f(x), 2 units to the right.
Let that function be g(x), then
[tex]g(x) = f(x - 2)[/tex]
We replace x by x-2 in f(x) to get:
[tex]g(x) = x - 2 + 8[/tex]
When we simplify, we obtain:
[tex]g(x) = x + 6[/tex]
22/25, end fraction of a number is what percentage of that number
Answer:
88%
Step-by-step explanation:
To get the percentage of 22/25. All that is needed to do is to multiply it with 100. Because A percentage is 100.
Thus: 22/25 gives 0.88 as a decimal, multiplied by the percentage figure 100
0.88 times 100 will give 88%.
Which means 22 is 88% of 25.
In other words to turn a fraction or decimal to a percentage, all that is needed to do of just to multiply that fraction or decimal by 100, and then it will give the percentage.

what is 1735/1000 written as a decimal?
Answer:
[tex]\frac{1735}{1000}[/tex] as a decimal is 1.735.
Step-by-step explanation:
To convert a fraction into a decimal, you first have to put the fraction into simplest form.
1. Simplest form
[tex]\frac{1735}{1000} = \frac{347}{200}\\\[/tex]
To do this you must find a number you can equally divide both numbers by.
That number in this situation, 5.
[tex]1000/5= 200\\1735/5= 347\\1735:1000 = 347:200\\\frac{1735}{1000} =\frac{347}{200}[/tex]
Now you must make this simplest formed fraction into a mixed number.
2. Simplest form into Mixed number
[tex]\frac{347}{200}= 1\frac{147}{200}[/tex]
To do this you see how many times the denominator, the bottom number of the fraction, goes into the numerator, the upper part of the fraction.
Since 200 x 2 = 400 and since 400 > 347 this means...
200 goes into 347, once.
Finally, subtract and divide.
Remember put the whole number in front of the mixed number, before the decimal
3. Subtract, divide, decimalize
[tex]147/200= 0.735\\\\1\frac{147}{200}= 1.735[/tex]
Hopes this helps you!

The volume of the smaller room is B. 768 cubic feet.
Step-by-step explanation:
Step 1:
The entire length for both rooms is 20 feet. As the large room has a length of 12 feet, the length of the smaller room is [tex]20-12=[/tex] 18 feet long.
The width of the prism is 12 feet and a height of 8 feet.
The volume of a rectangular prism is determined by multiplying its length, its width, and its height.
The small room's length = 8 feet,
The small room's width = 12 feet, and
The small room's height = 8 feet.
Step 2:
The volume of a rectangular prism [tex]= (l)(w)(h).[/tex]
The volume of the smaller room [tex]= (8)(12)(8)= 768.[/tex]
So the volume of the smaller room is 768 cubic feet which is option B.

1) Henna's cell phone company has a basic monthly plan of $60 plus $0.12
per minute. At the end of the month she was charged with a total of
$123.00. How many minutes has she used this month?
Answer:
525 Minutes
Step-by-step explanation:
The equation would be...
$60 + $0.12m = $123
Now we can simplify
($60 - $60) + $0.12m = ($123 - $60)
$0.12m = $63
($0.12m/$0.12) = ($63/$0.12)
M = 525
Jason went to the post office and bought both 41-cent stamps and 26-cent postcards and spent $10.28. The number of stamps was 4 more than twice the number of postcards. How many of each did he buy?
Solution:
Let stamps be s and postcards be p
Given that,
The number of stamps was 4 more than twice the number of postcards
s = 4 + 2p -------- eqn 1
Jason bought both 41-cent stamps and 26-cent postcards and spent $10.28
41 cent = $ 0.41
26 cent = $ 0.26
Therefore,
[tex]s \times 0.41 + p \times 0.26 = 10.28[/tex]
0.41s + 0.26p = 10.28 --------- eqn 2
Substitute eqn 1 in eqn 2
0.41(4 + 2p) + 0.26p = 10.28
1.64 + 0.82p + 0.26p = 10.28
1.08p = 10.28 - 1.64
1.08p = 8.64
Divide both sides by 1.08
p = 8
Substitute p = 8 in eqn 1
s = 4 + 2(8)
s = 4 + 16
s = 20
Thus Jason bought 20 stamps and 8 post cards
