A line that includes the points (- 3, - 10) and (- 4,v) has a slope of - 4. What is the value of v?

tekilochka [14]

Answer:

The value of v with given slop and points is - 6

Step-by-step explanation:

Given as :

Let x and y be the points of a line

So, x = ( - 3 , - 10 ) And y = ( - 4 , v )

The given slop of line XY is - 4

Now, from slop equation :

Slop = $\frac{(y2 - y1)}{(x2 - x1)}$

Or, - 4 = $\frac{(v + 10)}{(- 4 + 3)}$

Or, - 4 = $\frac{(v + 10)}{(- 1)}$

Or, v + 10 = ( -4 ) × (- 1 )

Or, v + 10 = 4

∴ v = 4 - 10 = - 6

Hence The value of v with given slop and points is - 6 Answer

Can anybody help me with this?

In the parenthesis: p^3/5 * p^2/5 = p^5/5 (You just add the exponents for multiplication)

p^5/5 is the same as p^1 or just p.

So now we have p^5 in our numerator and p^5 in our denominator. So that simplifies to 1.

The circle described by the equation <img src="https://tex.z-dn.net/?f=%28x-3%29%5E%7B2%7D%20%2B%28y%2B4%29%5E%7B2%7D%3D9" id="T

Answer:

The point at which center of the image circle located is (-2, -3) so second option is correct.

Step-by-step explanation:

Given equation of circle is:

$(x-3)^{2} + (y+4)^{2} = 9$ (i)

The general equation of circle is mentioned below,

$(x-h)^{2} + (y-k)^{2} = r^{2}$ (ii)

Here 'r' represents the radius of the circle and (h,k) shown the center of the circle.

By comparing equation (i) and equation (ii), we get

r^2 = 9

r = 3

$(x-3)^{2} = (x-h)^{2}$

$(x-3) = (x-h)$

$h = 3$

$(y+4)^{2} = (y-k)^{2}$

$(y+4) = (y-k)$

$k = -4$

So the center of given circle is (h,k) = (3,-4)

Also, the circle is translated 5 units left, that is towards the -x-axis. Therefore h = 3 - 5 = -2

Also, the circle is translated 1 unit up, that is towards the +y-axis. Therefore k = -4 + 1 = -3

Hence, the point at which center of the image circle located is (-2, -3) so second option is correct.

If (a+b)^2=54, and (a-b)^=46, then a^2+b^2=?

erastovalidia [21]

$(a+b)^2 =a^2 +b^2 + 2ab = 54~~~.....(i)\\\\(a-b)^2 = a^2 +b^2 -2ab = 46~~~.....(i)\\\\\\(i)+(ii):\\\\(a+b)^2 +(a-b)^2 = 54+46\\\\\implies a^2 +b^2 + 2ab + a^2 +b^2 - 2ab =100\\\\\implies 2a^2 +2b^2 =100\\\\ \\\implies 2(a^2 +b^2) =100\\\\\implies a^2 +b^2 = \dfrac{100}2 = 50$
