Answer:
-9
Step-by-step explanation:
The in the first expression, y is to the -9'th degree, which means n is -9.
(If there are numbers of similar term multiplied together, the exponents are to be added.)
Since you paid $3,625,you are paying $4323 in four years.
The easy way to do this is 4343(1+0.122)^4
you're paying 1212.6 per year which means you're paying $4850.4 so the total cost is $8475.4
Y=53.9 is the answer to your question
Answer:
Step-by-step explanation:
12 .x=3 y= -3
-x+2(y-1)
=-3+2(-3-1) = -3 -6 -2 = -9 -2 = -11
13.a=3
-5(a^2) -a + 5
=-5(3^2) -3 + 5 = -5(9) +2 = -45 +2 =-43
14. a = -2 b=4
-4a +3(2b-1)
= -4(-2) +3( 2(4)-1 ) =8 +3(8-1) = 8 +3(7) = 8 +21 =29
15. x = -2
3x^2 - 4x +1 =3(-2^2) -4(-2) +1 = 3(4) -4(-2) + 1 = 12 +8 +1 =20 +1 =21
