Arianna is saving money for college so she invests $1,000 into a savings account that earns interest every year. if the amount in the savings account is represented by the function
9x2+50x+1000, where x is the number of years. how much money does arianna have in her account after 6 years?

$1,624

Step-by-step explanation:

The amount after x-years is given as :

9 + 50x + 1000

Since x represents number of years , this means that after 6 years , the amount will be :

9( ) + 50(6) + 1000

⇒9(36) + 300 + 1000

⇒324 + 300 + 1000 =

Therefore, the amount after 6 years will be $1,624

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
