Solve by graphing. x2 2x - 8 = 0 a. –2, 4 b. 2, –4 c. 2, –4 d. –2, 4

Luba_88 [7]

Well, to solve, garph the equation y=x^2+2x-8 and y=0
see where they intersect

anyway the easier way is to factor but anyway
0=(x-4)(x+2)

anyway

solution is x=4 and -2

A and D are answers (they are same)

If m and n are whole numbers such that m^n = 121, then find the value of (m-1)^n+1.

stiv31 [10]

Because m and n are whole numbers, we only have 3 values for m, and 3 values for n :

$1^{121} ; 11^{11} ;121^{1}$ (or you can say because 121 only have the factors of 1 ; 11 ; 121, those are the only possible values for m and n, then conclude the possible values)

Now, we will substitute them in :

If m = 1 ; n = 121

$(1-1)^{121+1}$ = 0

If m = 11 ; n = 11

$(11-1)^{11+1}$ = 1000000000000

If m = 121 ; n = 1

$(121-1)^{1+1}$ = 14400
