A = 3x2(x - 1)
B = -3.23 + 4x2 –25 + 1

Not sure what you're asking, but if you just want the two expressions calculated, A = 6x - 6, or factored, 6(x-1); B = -19.23

Step-by-step explanation:

H1 is an exponential equation because each term divided by the previous term is a constant. so we have an equation of the form: y=ab^x, we can find a and b using two points.193606.4/186160=(ab^2)/(ab)1.04=b, so now we have: 186160=a(1.04)^1a=179000, so a(x) isa(x)=179000(1.04)^xb(x) is linear of the form y=mx+b because each term is a constant difference from the previous term.m=(y2-y1)/(x2-x1)m=(201000-190000)/(2-1)m=11000 so far we have: y=11000x+b, using the point (1,190000)190000=11000(1)+b179000=b so this equation b(x) is: b(x)=11000x+179000so the two equations for the home's values with respect to time, x, are: a(x)=179000(1.04)^x   and b(x)=11000x+179000since both houses have the same initial value, the exponential house, house a, will be considerably more valuable that the linear house in 30 years.a(30)=$580568.15   (to nearest cent)b(30)=$509000hope this .
