Remember that ^ has higher precedence than * or +, so in these expressions, parentheses are required: 1. (2)(3)x^(1+3) =6x^4 2. (4)^3 x^(1*3) y^(2*3) =64 x^3 y^6

-2 = (-2/3)(-6) + b -2 = 4 + b -2-4 = 4-4 +b -6 = b m = -2/3 y = mx + b y = -2x/3 +(-6) y = -2x/3 - 6

alg2 check?
first off, did you check to see whether x=4 fits the equation? 2(4)+2(4+3) =?= 2(4+7) 8 + 14 =?= 22 yes, so your answer is correct 2x+2(x+3)=2(x+7) 2x+2x+6 = 2x+14 4x+6 = 2x+14 2x = 8 x = 4 Looks like you nailed it. Good job.

Alg2
plug in all your info into the formula ( you have extra information) S(n) = a(r^n -1)/(r-1) 781 = a(5^5 - 1)/(5-1) 781 = a(3124/4) 781 = 781a a = 1 check: t(5) = 1(5^4) = 625
