Answer:
(6, 10)Step-by-step explanation:
Vertex form of an equation of a quadratic function is y=a(x-h)²+k, where vertex is (h, k)
We can find h and k by comleting the square:
[tex]y=x^2-12x+46\\\\y=x^2-2\cdot x\cdot\underline6+6^2-6^2+46\\\\y=\underline{x^2-12x+6^2}-36+46\\\\y=(x-6)^2+10\quad\implies\quad h=6\,,\ \,k=10\,,\ \,a=1[/tex]

35
X 2.5
Trevor read _______ pages this week.
Answer:
87.5 pages
Step-by-step explanation:
number of pages he read last week = 35
number of pages he read this week = 2.5 * number of pages he read last week
number of pages he read this week = 2.5 * 35
= 87.5 pages

Is 5(x - 3) = 5x + 15 the Distributive Property? Explain your answer with supporting equations.
Answer:
Distributive Property is when you break down numbers inside of parentheses.
Here are some Examples:
2(x + 2) = 3x + 65
5(x + 7) = 4x + 29
Yes, 5(x - 3) = 5x + 15 is the Distributive Property.

Answer:
Length: 40ft
Width: 15ft
Step-by-step explanation:
Since we're comparing the two and we know they equal the same perimeter I would write it out like so,
(x+25) + x = 2x + (x + 10)
Combine like terms to end up with...
2x + 25 = 3x + 10
-10 -10
2x + 15 = 3x
Subtract 2x from both sides which you get 15 = 1x (1x is the same as x)
x = 15
One side of Cat's driveway is x so that means it is 15ft and the other side (x+25) you replace the x with 15 and add. (15 + 25) which equals 40ft.
Hope that helps and have a great day!
Answer:
Length is 40ftWidth is 15ftStep-by-step explanation:
Since the perimeter of both driveways are the same, we can write an equation comparing the two.
(x + 25) + (x) = (2x) + (x + 10)
Now, we can solve for x.
(x + 25) + (x) = (2x) + (x + 10)
~Remove parenthesis and combine like terms
2x + 25 = 3x + 10
~Subtract 25 to both sides
2x = 3x - 15
~Subtract 3x to both sides
-x = -15
~Divide -1 to both sides
x = 15
Now that we know what x equals, we can find the length and width of Cats driveway.
Length:
x + 25
15 + 25
40
Width:
x
15
40 + 15 = 55ft
Therefore, the length is 40ft and the width is 15ft.
Best of Luck!

A builder wants to create a rectangular room in a house she wants it to have a total area of 375 square feet, and it should be 10 feet longer than it is wide
Answer:
Width = 15 ft
Length = 25ft
Step-by-step explanation:
Given that:
Total area = 375 ft²
Length = 10 + width
Let ;
Width = x
Length = x + 10
Area of a rectangle = Length * Width
Area of rectangle = 375 ft²
375 = x * (x + 10)
375 = X² + 10x
x² + 10x - 375 = 0
X² + 25x - 15x - 375 =. 0
x(x + 25) - 15(x + 25) = 0
x +. 25 = 0
x - 15 = 0
Hence,
x = - 25 or x = 15
X cannot be negative
Hence, x = 15
Width = 15 ft
Length = x + 10 = 15 + 10 = 25 ft
Suzie's Snakes and Salamanders Pet Shop has 38 snakes and 22
salamanders. If Suzie sells 9 snakes, what is the ratio of the remaining
unsold snakes to sold snakes?
Answer:

ratio of unsold to sold = 29÷9 = 3.2 : 1
The value of y is directly proportional to the value of x. If y = 45 when x =
180, what is the value of y when x = 80?
Step-by-step explanation:
y=45 when x=180 that is x is higher than y
4of y will give you 1of x that 45×4= 180
so when x is 80 so y will be 80÷4 that is 20
so y= 20

Help Asap!!! Name The Angle Pair And Find The Missing Value.
Answer:
Step-by-step explanation:
The two angles are vertically opposite. Vertically opposite angles are equal.
2 + 3x = 62 Subtract 2 from both sides
2-2+3x = 62-2
3x = 60 Divide by 3
3x/3 = 60/3
x = 20
The unknown part of the angle = 20
Answer:
vertical angles
X=20
Step-by-step explanation:
I know that the two angles have to be congruent because they are vertical angles. Congruent means that they equal each other so then the equation would be, 2+3x= 62
X=20

Select all tables that could represent a function.
Answer: A and E
A function is a relation for which each value from the set the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair.
From all tables, table A, table C and table E could represent a function.
What is function?"It is a relation between input and output values.""In function, for each input there is exactly one output."For given question,
We have been given five tables.
Here, column x represents input values and column y represents the output values.
For table A,
each input value distinct output.
Hence table A could represent a function.
For table B,
there are two outputs -4 and -6 for the input 3.
So, table B could not represent a function.
For table C,
There is distinct output for each input.
So, table C could represent a function.
For table D,
There are four output values for the input 3.
So, table D could not represent a function.
For table E,
There is distinct output for each input.
So, table E could represent a function.
Therefore, table A, table C and table E could represent a function.

Step-by-step explanation:
Let x = number of blocks in a bag.
4.
Left side = 2 bags & 7 blocks
Right side = 1 bag & 10 blocks
The beam is balanced, so the weights of the two sides are equal.
2x + 7 = x + 10
x = 3
There are 3 blocks in a bag.
5.
Left side = 3 bags & 6 blocks
Right side = 4 bags & 1 block
The beam is balanced, so the weights of the two sides are equal.
3x + 6 = 4x + 1
-x = -5
x = 5
There are 5 blocks in a bag.
Answer: 4. x+3x=x+1x
