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

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

Which equation describes the line with a slope of 5 and containing the point (2, 4) in slopeintercept form?

yulyashka [42]

Given m = 5 and point (2,4), the point-slope form is
y - y1 = m(x - x1)
y - 2 = 5x - 4
y = 5x - 4 + 2
y = 5x - 2

That is the line of the equation.
