Answer:
-10, 10
Step-by-step explanation:
To do that, we can set up an equation:
[tex]8x^2-800=0[/tex]
We can divide both sides by 8 to make it easier to solve:
[tex]x^2-100=0[/tex]
Now, isolate the x and take the square root of both sides:
[tex]x^2=100\\x=\pm10[/tex]
Therefore, the 2 zeroes of f(x) are -10 and 10.

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.

Answer:
4. 3
5. 5
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

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

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.

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

If you want step by step just comment and I’ll do it
Answer:
You need to multiply $2.70 cents is the answer. But with the markup, the price is $20.70
Step-by-step explanation:
You take the dollar amount, 18.00, and then multiply it by the percent, which we move the decimal since we are turning it into a decimal, since it is 15 we move the decimal two spots which makes it, 0.15.
