Liam was born on October 1, 2009. His grandparents put $20,000 into an account that yielded 3% interest compounded quarterly. When Liam turns 18, his grandparents will give him the money
for a college education. How much will Liam get on his 18th birthday?

the square root of what number? if you add that, then someone will probably answer the question.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
