Graph the equation.
y = |x – 11 – 2
Answer:Correct option is
A
10
Given y=(x−11)
2
⇒y=x
2
−22x+121
After substitute y=25. we get,
x
2
−22x+121−25=0
⇒x
2
−22x+96=0
⇒(x−16)(x−6)=0
⇒x=16,x=6
∴ two points are A,B are (16,25),(6,25).
Distance between A and B is
(16−6)
2
−(25−25)
2
=10
Hence, option A is correct.
Write the decimal in expanded form using fractions
0.801 = ???
Answer: 8/10 + 1/1000
Step-by-step explanation: in decimal form we have 0.800 + 0.001
to convert this into a fraction you'd do 8/10 + 1/1000
(8 is in the tenths place therefore 8/10 and 1 is in the thousandths place therefore 1/1000)

One number is two less than a second number. Five times the first is 8 more than 2 times the second. Find the numbers
what is the value of the first and second number?
Answer:
PLEASE MARK BRAINLIEST
Step-by-step explanation:
a+2= b
5a - 8 =2b
a= b- 2
since(a= b- 2)
5(b-2) -8 = 2b
5b -10 - 8 = 2b
3b -18 =0
3b=18;b=6
since b =6
a= 6-2 ; a= 4

I'm stuck in math class and I have no clue how to do it- lol :')
Answer:
c = 9
Step-by-step explanation:
first, simplify 30/2c. which is 15/2c. then cross multiply. 15 x 12 = c x 20.
you get 180 = c x 20. swap sides, c x 20 = 180. divide both sides by 20, then simplify to get 9.
hope this helps.

( 8n - 3n^4 + 10n ^2 ) - ( 3n^2 + 11n ^4 - 7)
-14n⁴ + 7n² + 8n + 7
Step-by-step explanation:
(8n - 3n⁴ + 10n²) - (3n² + 11n⁴ - 7)
= 8n - 3n⁴ + 10n² - 3n² - 11n⁴ + 7
= -3n⁴ - 11n⁴ + 10n² - 3n² + 8n + 7
= -14n⁴ + 7n² + 8n + 7

PLEASE SOMEONE WHO IS SMART ANSWER THIS QUESTION
Answer:
36/32 or 1 1/8 (same thing)
Step-by-step explanation:
9 gallon / 32 quarts
First, you have to convert 9 gallon to quarts to match the denominator. In the table, it says that 1 gallon = 4 quarts, so you have to do, 9 x 4 which gives you 36. Now that the fraction is in the same form of units, 36 quarts / 32 quarts, you will have to write it as a mix fraction or you can just leave it as 36 quarts / 32 quarts. If you want it in mix fraction, it is 1 1/8.
Answer:
36
Step-by-step explanation:
1 gallon is 4 quart then the question is 1 to 9 quart then is 4 * 9 is 36

Step-by-step explanation:
Alegebra. Identify the vertex and axis of symmetry of each. Please answer and e0lain how and why you got your answers.
There is no information displayed.
Here is how to do it.
How to calculate axis of symmetry:
Plug your numbers into the axis of symmetry formula. To calculate the axis of symmetry for a 2nd order polynomial in the form ax 2 + bx +c (a parabola), use the basic formula x = -b / 2a. In the example above, a = 2 b = 3, and c = -1. Insert these values into your formula, and you will get:
How to calculate vertex:
The vertex form of a quadratic is given by
y = a(x – h)2 + k, where (h, k) is the vertex.
The "a" in the vertex form is the same "a" as
in y = ax2 + bx + c (that is, both a's have exactly the same value). The sign on "a" tells you whether the quadratic opens up or opens down. Think of it this way: A positive "a" draws a smiley, and a negative "a" draws a frowny. (Yes, it's a silly picture to have in your head, but it makes is very easy to remember how the leading coefficient works.)
In the vertex form of the quadratic, the fact that (h, k) is the vertex makes sense if you think about it for a minute, and it's because the quantity "x – h" is squared, so its value is always zero or greater; being squared, it can never be negative.
Suppose that "a" is positive, so a(x – h)2 is zero or positive and, whatever x-value you choose, you're always taking k and adding a(x – h)2 to it. That is, the smallest value y can be is just k; otherwise y will equal k plus something positive. When does y equal only k? When x – h, the squared part, is zero; in other words, when x = h. So the lowest value that y can have, y = k, will only happen if x = h. And the lowest point on a positive quadratic is of course the vertex.
If, on the other hand, you suppose that "a" is negative, the exact same reasoning holds, except that you're always taking k and subtracting the squared part from it, so the highest value y can achieve is y = k at x = h. And the highest point on a negative quadratic is of course the vertex.

3/6 = n/2
proportional relationships
Answer:
1.
Step-by-step explanation:
Do cross multiplying, 3 x 2 = 6
6 divided by 6 = 1
n = 1
Answer:
n = 1
Step-by-step explanation:
3/6 = n/2 Find the greatest common factor of the numerator and denominator
1:3/2:3 = n/2 Factor out and cancel the greatest common factor
1/2 = n/2 Swap sides
n/2 = 1/2
Line f passes through points (8, 7) and (3, 10). Line g passes through points (5, 7) and (10, 4). Are line f and line g parallel or perpendicular?
Answer: Parallel
Step-by-step explanation:
First find slope.
Line f: [tex]\frac{10-7}{3-8} =-3/5[/tex]
Line g: [tex]\frac{4-7}{10-5}=-3/5[/tex]
Since the slopes are the same, the lines are parallel.
First we need to find the slope of each line
Slope of line f
(8 , 7) (3 , 10)
[tex]slope = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
[tex]slope = \frac{10-7}{3-8}[/tex]
[tex]slope = \frac{3}{-5}[/tex]
[tex]slope=-\frac{3}{5}[/tex]
Slope of line g
(5 , 7) (10 , 4)
[tex]slope = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
[tex]slope = \frac{4-7}{10-5}[/tex]
[tex]slope = \frac{-3}{5}[/tex]
[tex]slope=-\frac{3}{5}[/tex]
The two lines have the same slope therefore they are not perpendicular but instead parallel to each other.

Answer:
angle OPN, angle PON, angle NOP, angle PNO
Step-by-step explanation:
Essentially, this simply asks what angles contain the line OP. If we draw the triagnle NOP (in that order starting at the top), we can see that all these angles include the line OP within their angles.
(note: Im not sure if it is asking for the line OP in that order. If so, it would only be angles 1 and 3, as those have OP in that order)
