thus the given equation is a linear equation in two variables ...
thus ploting a table we get as ...
y = -5x + 3
there fore
1) at y=0 , x = 3/5 .... 0 = -5x +3
= -5x = -3 ..thus X = 3/5
2) at x=0 , y= 3 ...
y = -5 (0) + 3 = 3
3) at X =1 , y = -2
4) at y=1 , x = 2/5
Answer:
h = 9 cm.
Step-by-step explanation:
V = kBh where k is the constant of variation.
From the given info:
32 = k*16*6 = 96k
So k = 32/96 = 1/3.
So we have the equation of variation:
V = 1/3Bh
When V = 60 B = 20, so:
60 = 1/3 20h
20h = 60 * 3 = 180
h = 180 /20 = 9.
The general formula for the lateral surface area of a right prism is
L = ph
where p represents the perimeter of the base and h represents the height of the prism.
In our case, the perimeter is the sum of the bases.
p = 5 + 5.6 + 2.5 = 13.1 cm
now, the height of the prism is 8 cm
then L = 13.1 cm x 8 cm = 104.8cm^2
