Answer:
The equation of the relation ⇒
y = 18
Step-by-step explanation:
∵ y ∝ x/z
∴ y = kx/z
∵ y = 18 , x = 15 and z = 5
∴ 18 = 15k/5 ⇒ 18 = 3k
∴ k = 18/3 = 6
∴ y = 6x/z
∵ x = 21 and z = 7
∴ y = (6 × 21)/7 = 18
All values of x 5 ( x + 10 )^2 − 30 = − 5 Plzzzz

Answer:
Option B.
Step-by-step explanation:
Given:
-3( -x + a ) + 7 < 5 When x = -1
To Find:
a ?
Solution:
-3( -x + a ) + 7 < 5 When x = -1
Substitute x = -1 in above we get
-3(-(-1) + a ) + 7 < 5
-3(1 + a) < 5 - 7
Using Distributive Property we get i.e A(B+C) = AB + AC
