the interest earned on an account varies directly with the balance in the account. if an account with a balance of $200 earns $1

liq [111]

Answer:

$\$31.25$

Step-by-step explanation:

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

Let

y-------> the interest earned on an account

x------> the balance in the account

step 1

Find the constant k of proportionality

For $x=\$200,y=\$12.50$

$k=y/x$

substitute the values

$k=12.50/200=0.0625$

The equation is

$y=0.0625x$

step 2

Find the amount of interest earned on an account with a balance of $500

For $x=\$500$ substitute in the equation and solve for y

$y=0.0625(500)=\$31.25$

Re-write the quadratic function below in Standard Form<br> y= -(x – 8)^2 +4

s2008m [1.1K]

Answer:

$y = - {(x - 8)}^{2} + 4 \\ = - ( {x}^{2} - 16x + 64) + 4 \\ = - {x}^{2} + 16x - 64 + 4 \\ y= - {x}^{2} + 16x - 60$
