B is correct.  The distance formula can be written correctly in several different ways.  Examples:

sqrt( change in x)^2 + (change in y)^2 ) 

sqrt( (x2-x1)^2 + (y2-y1)^2 )

Only find the vertex and axis of symmetry
lara [203]

Answer:

vertex (5,2)

axis of symmetry: x=5

Step-by-step explanation:

vertex (h,k)

y = a(x - h)² + k

f(x)=(x-5)²+2        a = 1     h = 5      k = 2

vertex (5 , 2)

The axis of symmetry always passes through the vertex of the parabola. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

x = 5

Find the slope of the line passing through the given points.
deff fn [24]

Answer:

<h3>The answer is - 3</h3>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

From the question we have

m =  \frac{8 - 5}{ - 8 -  - 7}  =  \frac{3}{ - 8 +7 }  =   - \frac{3}{1}  =  - 3 \\

We have the final answer as

<h3>- 3</h3>

Hope this helps you

5+3=4d please help me
ad-work [718]
So the object of this problem is to find out the value of d.

To do this, first think about 5 + 3. This equals 8, right? So the value of d times 4 has to equal 8.

No other number besides 2 would make sense. 2 would equal d because 4 x 2 is 8, and 5 + 3 is 8.

So you would write the answer as:

5+3=4(2)
