Answer:
If they have the same variables. For example 2x -1 + 3x. 2x and 3x are like terms since they have the same variable.
Step-by-step explanation:
I think the best answer is A.
Step-by-step explanation:
i. 3x-1=20
or, 3x= 21
x= 7
ii. 3x+1= 22
3x= 21
x= 7
iii. 2x-5=99
2x= 104
x=52
iv. g(3)= 3+5/2= 11/2
g(0)= 0+ 5/2=5/2
g(-3)= -3+5/2 = -1/2
x+5/2= 0
so, x= -5/2
Answer:
0.50
Step-by-step explanation:
X ___ - 5 ___ 3 __ - 2 __ 0 __ 12 __ 3
P(x) __0.17_0.13_0.33 _0.16 _0.11 _0.10
P(x <0) = p(x = - 2) + p(x = - 5)
P(x < 0) = 0.33 + 0.17
P(x < 0) = 0.50

Answer:
0.6 probability that 
Step-by-step explanation:
The probability distribution is given in the table.
Probability that x is between -2 and 2.
Between -2 and 2, inclusive, we have -2, 0 and 2. So
From the table:
. So
0.6 probability that
