X is partly constant and partly varies with y wheny=3,x=11,and when y=4 x=14.(a)find the relationship between x and y (b)find the x when y=10.

Answer 1

a = ay+b
Using the two points,
3a+b=11
4a+b=14
so, a=3, b=2

x = 3y+2
x(10) = 32

Answer 6

X is partly constant and partly varies with y when y=3x=11 and when y=4x=14

Answer 7

Given, X is partly constant and partly varies with y.

When y=3, x=11 and when y=4, x=14.

Let's find the constant part and the part that varies with y.

Let, X = k + a*y

where, k = constant part
a = part that varies with y

Using the first set of values, we get

11 = k + 3a ---(1)

Using the second set of values, we get

14 = k + 4a ---(2)

Solving (1) and (2) simultaneously,

k = 2

a = 3

Therefore, the relationship between x and y is given by:

X = 3y + 2

To find the value of x when y=10,

X = 3*10 + 2 = 32.
