Powers of 2 are ...
... (x, 2^x) ∈ {(0, 1), (1, 2), (2, 4), (3, 8), (4, 16), (5, 32), (6, 64), (7, 128), (8, 256), (9, 512), (10, 1024)}
By the rules of exponents, ...
... 1/a^b = a^-b
Using the above table, ...
a) 1 = 2^0
b) 1/4 = 2^-2
c) 1/64 = 2^-6
d) 1/256 = 2^-8
e) 64 = 2^6
f) 1/16 = 2^-4
g) 256 = 2^8
h) 1/1024 = 2^-10
Exact form = 7/3
Decimal = 2.3
Mixed number Form = 2 1/3
Answer: Not Function
Step-by-step explanation:
The pattern is not consistent.
Answer:
Step-by-step explanation:
Simplifying
(15x + -2) + (7x + 4) = 90
Reorder the terms:
(-2 + 15x) + (7x + 4) = 90
Remove parenthesis around (-2 + 15x)
-2 + 15x + (7x + 4) = 90
Reorder the terms:
-2 + 15x + (4 + 7x) = 90
Remove parenthesis around (4 + 7x)
-2 + 15x + 4 + 7x = 90
Reorder the terms:
-2 + 4 + 15x + 7x = 90
Combine like terms: -2 + 4 = 2
2 + 15x + 7x = 90
Combine like terms: 15x + 7x = 22x
2 + 22x = 90
Solving
2 + 22x = 90
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2' to each side of the equation.
2 + -2 + 22x = 90 + -2
Combine like terms: 2 + -2 = 0
0 + 22x = 90 + -2
22x = 90 + -2
Combine like terms: 90 + -2 = 88
22x = 88
Divide each side by '22'.
x = 4
Simplifying
x = 4
