First you have to change y to x
X= 2y+5/2
Then find y
(X-5/2)/2=y
So (X-5/2)/2 is the. Inverse function
Answer:
1) 4 days 2) P30 3) P125 4) 6 adult 5) smallest number : 57.77 largest number = 72.22
Step-by-step explanation:
1)
6 litres --> 3 days
1 litres --> 1/2 days
8 litres --> 1/2 * 8 = 4 days
2)
3 ball pens --> P18
1 ball pens --> P6
5 ball pens --> P30
3)
12 pencils --> P60
1 pencils --> P5
25 pencils --> P125
4)
7 children --> 2 adults
1 chldren --> 2/7 adults
21 children --> 2/7 * 21 = 6 adult
5) 4:5
4x+5x=130
x = 130/9
4x = 57.77
5x = 72.222
Answer:
The given points isn't define a parallelogram.
Step-by-step explanation:
As we know,
⇒ The opposite sides of a parallelogram are equal.
The given points are:
(x1, y1) = M(2,4)
(x2, y2) = I(1,2)
(x3, y3) = L(5,1)
(x4, y4) = K(4,−1)
Now,
On applying the Distance formula, we get
MI =
On substituting the given values, we get
=
=
=
IL =
=
=
=
LK =
=
=
=
KM =
=
=
=
Here, MI = LK = √5
IL ≠ KM
