Answer:

x=17

Step-by-step explanation:

2(x-7)=(x+3) divide both sides by two

2x-14 =(x+3) distribute

2x-14-x-3=0 substract x+3  

x-17=0 combine like terms

x=17 add 17 to both sides

Vaselesa [24]

EXPLANATION:

Given;

f(x)=4^{x-1}

Required;

We are required to calculate the value of the function at the input levels indicated.

Step-by-step solution;

To solve the problem, we shall evaluate the function by taking the value of the function at the value given (in place of x).

\begin{gathered} (i) \\ f(4)=4^{(4-1)} \end{gathered}f(4)=4^3f(4)=64

For the second part;

f(8)=4^{(8-1)}f(8)=4^7f(8)=16,384

Therefore, the function is valued as follows;

ANSWER:

\begin{gathered} f(4)=64 \\ f(8)=16384 \end{gathered}

pantera1 [17]

Answer:

Mia is correct

Step-by-step explanation:

The outer triangle and the inner triangle are similar ( AA postulate )

Then the ratios of corresponding sides are in proportion

\frac{2}{2+6} = \frac{3}{x} , that is

\frac{2}{8} = \frac{3}{x} ( cross- multiply )

2x = 24 ( divide both sides by 2 )

x = 12
