Answer:

-6=7 NO SOLUTION

Step-by-step explanation:

First, distribute the -3 to the (k +2)

Your equation becomes, -3k-6=-3k+7

Add 3k to both sides to have the variables be on the same side

Your equation becomes, -6=7

Since that isn’t true, it’s a no solution

I hope this helps!

Three vertices of parallelogram WZXY are W(-5, 2), X(2, 4) and Z(-7, -3). Find the coordinated of the vertex, Y.
Dominik [7]

Answer:

Y = (4,9)

Step-by-step explanation:

Given

W(x_1,y_1) = (-5, 2)

Z(x_4,y_4) = (-7, -3)

X(x_2,y_2) = (2, 4)

Required

Find Y

To do this, we make use of the mid-point formula

i.e.

M = \frac{1}{2}(x_n+x_m,y_n+y_m})

WX and ZY are the diagonals of the parallelogram.

The mid-point of WX is:

M = \frac{1}{2}(-5+2,2+4)

M = \frac{1}{2}(-3,6)

The mid-point of ZY is:

M = \frac{1}{2}(-7+x,-3+y)

Equate both values of M

\frac{1}{2}(-3,6) = \frac{1}{2}(-7+x,-3+y)

Multiply both sides by 2

(-3,6) = (-7+x,-3+y)

By comparison:

-7 + x = -3

-3 + y = 6

-7 + x = -3

x = 7 -3

x = 4

-3 + y = 6

y = 6 +3

y = 9

Hence:

Y = (4,9)
