Hello from MrBillDoesMath!

Answer:

11

Discussion:

Solution by distance formula:

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

  = sqrt (  (-1 - (-1) )^2 + (4 - (-7))^2 )

  = sqrt (   ( -1 + 1) ^2 + (4+7)^2)

  = sqrt (   0^2           + 11^ 2    )

  = sqrt ( 11^2)

  = 11

Solution by contemplation!

Note the x coordinate of both points is the same (i.e. -1)  This means the line joining the points is vertical and its length is simply the difference of the y coordinates:   4 - (-7) = 4 + 7 = 11

Thank you,

MrB

What is the least common denominator of 7/x^2 7/5x explain
Usimov [2.4K]
See the denomenators

x^2 and 5x

factor each
x^2=x*x
5x=5*x

lcd=5*x*x or 5x^2

the factions would be 35/5x^2 and 7x/5x^2

Princess Poly claims that the equation (3x−4i)(7x−8)(3x+4i)=0 has three roots, a real root and a complex root with a multiplicit
Serjik [45]

Given equation:

(3x-4i)(7x-8)(3x+4i)=0

i.e., 3x-4i=0       and       7x-8=0       and       3x+4i=0

i.e., 3x=4i       and       7x=8       and       3x=-4i

i.e., x=\frac{4i}{3}       and       x=\frac{8}{7}       and       x=-\frac{4i}{3}

Therefore, the given equation has a real root i.e., x=\frac{8}{7}

and two complex conjugate roots i.e., x=\frac{4i}{3} and x=-\frac{4i}{3}

Hence, option C is correct.

Find an equation for the line with slope m through the point (a,c).
lidiya [134]
If you want the answer in point slope form then,

y-y1 = m(x-x1)
y-c = m(x-a)

---------------------------------------

If you want the answer in slope intercept form, then solve for y

y-c = m(x-a)
y-c = mx-ma
y-c+c = mx-ma+c
y = mx-ma+c
y = mx+c-ma
y = mx+(c-ma)

For this answer in slope intercept form the slope is m and the y intercept is c-ma

---------------------------------------

If you want the answer in standard form, then get the variable terms to the left side. Have the constant terms on the right side.

y = mx+c-ma
y-mx = mx+c-ma-mx
-mx+y = c-ma

Optionally you can multiply both sides by -1 to get mx-y = -c+ma but it will depend on your book if this step is carried out or not.
