Let t1 and t2 be linear transformations given by t1 x1 x2 = 2x1 + x2 x1 + x2 t2 x1 x2 = 8x1 + 7x2 x1 + x2 . find the matrix a such that the following are true. (a) t1−1(t2(x)) = ax a = (b) t1(t2−1(x)) = ax a = (c) t2−1(t1(x)) = ax a = (d) t2(t1−1(x)) = ax a =

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

the answer is d
