Answer:
(-8x - 12) + (9x + 4)= x-8
(-3p^3 + 5p^2 - 2p) + (3r^2 - 3r)= -3p^3+5p^2-2p+3r^2-3r
( -3p^3 + 5p^2 - 2p) + (-p^3 - 8p^2 -15p)= -4p^3-3p^2-17p
. ( 9r^2+4r-7) + (3r^2-3r)= 12r^2+r-7

Inequality is the phrase that contains variables or numbers and inequality symbols like < or > or <= or >=
option A goes not have inequality symbol , so it is not an inequality
Option B has > symbol. It is an inequality
Option C has < symbol. It is an inequality
Option D has < symbol. It is an inequality
Option E has only fraction. So it is not an inequality
Answer:
Option (C)
Step-by-step explanation:
If two functions are f(x) and k(x),
(f o g)(x) = f[g(x)]
From the question given in the picture attached,
We have to find the value of (h o k)(1).
(h o k)(x) = h[k(x)]
= h[k(1)]
= h(3) [Since, k(1) = 3]
= 28 [Since, h(3) = 28]
Therefore, (h o k)(1) = 28 will be the answer.
Option (C) will be the correct option.
Answer:
Policeman A = 56 tickets
Step-by-step explanation:
Policemen A + B = 70
If Policeman B hands out x no of tickets...
Then Policeman A hands out 4x no of tickets
meaning...
x + 4x = 70
5x = 70
x = 70/5
x = 14
Therefore Policeman A hands out..
4x = 4 × 14 = 56 tickets
