I believe only one line because perpendicular lines must have 90 degrees angles.

IF m power n is equal to 32 wher m and n are natural numbers then find the value of n power m

xxTIMURxx [149]

Answer:

$n^m = 5^2$

Step-by-step explanation:

Given

$m^n = 32$

Required

Find $n^m$

$m^n = 32$

Express 32 as an exponent

$m^n = 2^5$

By comparison:

$m = 2$

$n = 5$

So:

$n^m = 5^2$

Answer:

$\large\boxed{C.\ y=2+x^4}$

Step-by-step explanation:

The slope-intercept form of an equation of linear function:

$y=mx+b$

m - slope

b - y-intercept

============================

$A.\\\\9y+3=0\qquad\text{subtract 3 from both sides}\\\\9y=-3\qquad\text{divide both sides by 9}\\\\y=-\dfrac{3}{9}\\\\y=-\dfrac{1}{3}\to m=0,\ b=-\dfrac{1}{3}$

$B.\\\\y-4x=1\qquad\text{add}\ 4x\ \text{to both sides}\\\\y=4x+1\to m=4,\ b=1$

$C.\\\\y=2+x^4\qquad\text{nonlinear, because}\ x\ \text{is in fourth power}$

$D.\\\\x-2y=7\qquad\text{subtract}\ x\ \text{from both sides}\\\\-2y=-x+7\qquad\text{divide both sides by (-2)}\\\\y=\dfrac{1}{2}x-\dfrac{7}{2}\to m=\dfrac{1}{2},\ b=-\dfrac{7}{2}$

$E.\\\\\dfrac{x}{y}+1=2\qquad\text{subtract 1 from both sides}\\\\\dfrac{x}{y}=1\to y=x\to m=1,\ b=0$
