Finbar bought his home for $150,000 in 2010. Property values have increased 10% every year since he has owned the home. Which of the following equations can be used to represent the price of the home x years after 2010? y = 150,000(1. 5)x y = 150,000(1. 1)x y = 150,000(0. 9)x y = 150,000(0. 5)x.

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
