If 3x-y=123x−x=123, x, minus, y, equals, 12, what is the value of \frac{8^x}{2^y} 2 y 8 x start fraction, 8, start superscript

nlexa [21]

Answer:

$\frac{8^x}{2^y}$ = 4096

Step-by-step explanation:

Rules:

$\frac{a^m}{a^n}=a^{m-n}$
$a^m\times a^n= a^{m+n}$
$(a^m)^n=a^{m\times n}$

Given that,

3x-y =12

Therefore

$\frac{8^x}{2^y}$

$=\frac{(2^3)^x}{2^y}$ [ since $8=2^3$ ]

$=\frac{2^{3x}}{2^y}$ [ applying 3rd rule]

$=2^{3x-y}$ [ applying 2nd rule]

$=2^{12}$ [ since 3x-y =12]

=4096

Evaluate f(x) = X(With an exponent of 2) -3x +2, given f(x + 1).

Lana71 [14]

Answer:

f(x + 1) = x² - x

Step-by-step explanation:

f(x) = x² - 3x + 2 when f(x + 1)

f(x + 1) = (x + 1)² - 3(x + 1) + 2

f(x + 1) = (x² + 2x + 1) + (-3x - 3) + 2

f(x + 1) = x² - x + 0

f(x + 1) = x² - x

Best of Luck!
