Answer:
x = 2
Step-by-step explanation:
3(x - 1) = 23 - 5(x + 2) ← distribute parenthesis on both sides
3x - 3 = 23 - 5x - 10
3x - 3 = 13 - 5x ( add 5x to both sides )
8x - 3 = 13 ( add 3 to both sides )
8x = 16 ( divide both sides by 8 )
x = 2
So the said problem asking to explain or justify why the initial value of any function of the form f(x) = a(bx) is equal to a. For me I won't agree with the said question, the said function is determine through the value of X because it is the undefined value in the equation that is needed to be define. I hope this would help
Answer:
-2ab • (3a - b - 4)
Step-by-step explanation:

Answer:
Step-by-step explanation:
Let's start defining the conditional probability of an event :
Given two events A and B :
with P(B) > 0
Where P(A/B) is the probability of event A given that event B occur
P(A,B) is the probability of the event in which A and B occur both at the same time.
Let's write the events for our exercise
S : ''A random student speaks Spanish''
I : ''A random student speaks Italian''
Applying the conditional equation we obtain :
Then, 0.375 is the probability that we are looking for
12) 2b+8a
13) 17y^2-22y
14) 9m^2n+7mn^2
15) 11y^2
16) 8x^2y
