Your friend says that the absolute value equation | 3x+8 |-9=-5 has no solution because the constant

sineoko [7]

Answer:

Incorrect

Step-by-step explanation:

We are given the equation:

$\displaystyle \large{|3x+8|-9=-5}$

Add both sides by 9.

$\displaystyle \large{|3x+8|-9 + 9=-5 + 9} \\ \displaystyle \large{|3x+8|=4}$

When we want to tell if the absolute equation has solutions or not, we have to simplify in this form first: or isolate the absolute sign.

$\displaystyle \large{ |ax + b| = c}$

If c ≥ 0, the equation has solutions.

If c < 0, the equation does not have solutions.

Therefore, it does not always matter if the constant on right side is in negative because if there is a number on the left side then there is a chance that the equation has solutions.

From |3x+8| = 4 is equivalent |3x+8|-9=-5 and the right side is 4 which is positive.

Hence, the equation does have a solution!

SpyIntel [72]

$|\Omega|=C(16,2)=\dfrac{16!}{2!14!}=\dfrac{15\cdot16}{2}=120\\|A|=C(6,2)+C(10,2)=\dfrac{6!}{2!4!}+\dfrac{10!}{2!8!}=\dfrac{5\cdot6}{2}+\dfrac{9\cdot10}{2}=15+45=60\\\\P(A)=\dfrac{60}{120}=\dfrac{1}{2}=50\%$
