Question

1) u and y vary directly with each other. When u is 10, v is 15. Write an equation connecting u and
V. Also write four possible pairs of values of u and y.
​

Answer 1

here is your answer plzz mark brainliest

Step-by-step explanation:

1 ) v -u = 5

2) v +u = 25

3) v * u = 150

4) v/u = 3/2

Answer 2

Equation is $u =\dfrac{2}{3}v$

Pairs are (1, 2/3), (2, 4/3), (3, 2) and (4, 8/3)

Step-by-step explanation:

Given,

u and v vary directly with each other

i.e. u ∝ v

⇒ u = kv                    ......(1)

If u = 10 and v = 15,

From eq (1),

10 = k(15)

$\implies k =\frac{10}{15}=\frac{2}{3}$

Again from eq (1),

The equation that shows the relation between u and v,

$u =\frac{2}{3}v$

if v = 1, $u=\frac{2}{3}(1)=\frac{2}{3}$

if v = 2, $u=\frac{2}{3}(2)=\frac{4}{3}$

if v = 3, $u=\frac{2}{3}(3)=2$

if v = 4, $u=\frac{2}{3}(4)=\frac{8}{3}$
