−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)

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.

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)

Answer:
Jacob could compare the unit rates of cost per ounce. The unit rate that is less per ounce is the better deal. Not He can look at the cost per ounces!
Step-by-step explanation:
Answer:
Compare the unit rates.
The unit rate shows the cost for each ounce.
The lesser unit rate costs less per ounce.
The brand with the lesser unit rate is the better value.

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.
