Answer:

x=90

Step-by-step explanation:

Let's solve your equation step-by-step.

x/9−5=5

Step 1: Simplify both sides of the equation.

x/9−5=5

1/9x+−5=5

1/9x−5=5

Step 2: Add 5 to both sides.

1/9x−5+5=5+5

1/9x=10

Step 3: Multiply both sides by 9.

9*(1/9x)=(9)*(10)

x=90

Answer:

x=90

ASAAPPPPPP!!!!! Complete the tables of values

velikii [3]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

$a^{-m}$ ⇔ $\frac{1}{a^{m} }$ and $a^{0}$ = 1

Substitute the values of x into $4^{-x}$

x = 0 → $4^{0}$ = 1 ⇒ a = 1

x = 2 → $4^{-2}$ = $\frac{1}{4^{2} }$ = $\frac{1}{16}$ , hence

b = $\frac{1}{16}$

x = 4 → $4^{-4}$ = $\frac{1}{4^{4} }$ = $\frac{1}{256}$ , hence

c = $\frac{1}{256}$
