Answer:
7.5
Step-by-step explanation:
2x+12=6x-18
2x=6x-30
-4x=-30
x=7.5
Answer:
very easy
Step-by-step explanation:
First of all
made a distance between
AB
BC
CD
AD
and diagnals
AC
BD
If the all are equal means it is a square
if diagnols are different means it is rectangle
if diagnals are not equal means it is parallelogram
thats it try your best
you can do it
best of luck
Answer:
k = 5 and (6,2).
Step-by-step explanation:
Since (1,-1) is a solution of the equation 3x - ky = 8, so the point (1,-1) will satisfy the equation above.
Hence, putting x = 1 and y = -1 in the equation will give left-hand side = right-hand side.
So, 3(1) - k(-1) = 8
⇒ 3 + k = 8
⇒ k = 5 (Answer)
Therefore, the equation of the straight line is 3x - 5y = 8 ....... (1)
Now, putting x = 6 , then from equation (1) we get y = 2
Therefore, (6,2) is also a point on the graph of equation (1). (Answer)
