By solving the equation:

4b + 6 = -2

4b = -2 - 6 (taking 6 from each side)

4b = -8

b = -2 (divide both sides by 4)

A set W of strings of symbols is defined recursively by 1. a, b, and c belong to W. 2. If x belongs to W, so does a(x)c. Which o

Vadim26 [7]

Answer:

a. a(b)c

b. a(a(b)c)c

d. a(a(a(a)c)c)c

Step-by-step explanation:

We are given the following in the question:

$a,b,c \in W\\\text{If } x \in W \Rightarrow a(x)c \in W$

a. a(b)c

It is given b belongs to W.

$b \in W\\\Rightarrow a(b)c \in W$

b. a(a(b)c)c

$a(b)c \in W\\\Rightarrow a(a(b)c)c \in W$

c. a(abc)c

a(abc)c does not belong to W because we cannot find x in W such that a(abc)c belongs to W.

d. a(a(a(a)c)c)c

$a \in W\\\Rightarrow a(a)c \in W\\\Rightarrow a(a(a)c)c \in W\\\Rightarrow a(a(a(a)c)c)c$

e. a(aacc)c

a(aacc)c does not belong to W because we cannot find x in W such that a(aacc)c belongs to W.

Answer:

$\large\boxed{1.\ f^{-1}(x)=\sqrt[12]{3^x}}\\\\\boxed{2.\ f^{-1}(x)=\sqrt[4]{3^x}}\\\\\ \boxed{3.\ f^{-1}(x)=\sqrt[3]{4^{7-x}}}$

Step-by-step explanation:

$(a^n)^m=a^{nm}\\\\\log_ab=c\iff a^c=b\\\\a^{\log_ax}=x\\\\n\log_ab=\log_ab^n\\\\\log_ab+\log_ac=\log_a(bc)\\============================\\\\1.\\y=3\log_3x^4\to y=\log_3(x^4)^3\to y=\log_3x^{12}$

$2.\\y=\log_3x^4\\\\\text{Exchange x and y. Solve for y:}\\\\\log_3y^4=x\Rightarrow3^{\log_3y^4}=3^x\Rightarrow y^{4}=3^x\\\\y=\sqrt[4]{3^x}\\-------------------------$

$3.\\y=-\log_4x^3+7\\\\\text{Exchange x and y. Solve for y:}\\\\-\log_4y^3+7=x\qquad\text{subtract 7 from both sides}\\\\-\log_4 y^3=x-7\qquad\text{change the signs}\\\\\log_4y^3=7-x\Rightarrow4^{\log_4y^3}=4^{7-x}\\\\y^3=4^{7-x}\Rightarrow y=\sqrt[3]{4^{7-x}}$

What is p equal to? Also if you could, can you tell me how you do it so I can do the rest by myself.

svp [43]

Answer:

p=-54

Step-by-step explanation:

$- \frac{p}{6} = 9 \\ \frac{ - p}{6} = 9 \\ \frac{ - p}{6} \times 6 = 9 \times 6 \\ - p = 54 \\ p = - 54$
