Answer:

 Roni did not make use of the equation for a proportional relationship.

Step-by-step explanation:

For some constant of proportionality k, y is proportional to x if x and y satisfy the equation ...

  y = kx

Roni knows k=7/25, but she did not use this equation. She added instead of multiplying, so did not end with an equation expressing a proportional relation.

___

  y = (7/25)x

If you invest $500 at 4% interest,compounded annually,how much is in the account at the end of six years?
Genrish500 [490]
So, we'll find out how much interest this person will have in 6 years and then add it to the original deposit. To do this we will multiply all the factors:

500 x 0.04 x 6 = 120.
This means they'll have made $120 in interest in 6 years if they don't touch the money. We will add the 120 to the 500.
500+120= 620

They will have a total of $620 in their account after 6 years.

What is the equation of the line that passes through the point (5,6) and has a slope of 2?
pantera1 [17]

Answer:

Answer is at the bottom!!

Step-by-step explanation:

y = - \frac{2}{5} x - 2

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange 2x + 5y = 10 into this form

subtract 2x from both sides  

5y = - 2x + 10 ( divide all terms by 5 )

y = - \frac{2}{5} x + 2 ← point- slope form with slope m = - \frac{2}{5}

Parallel lines have equal slopes hence  

y = - \frac{2}{5} x + c is the partial equation of the parallel line

to find c, substitute ( 5, - 4 ) into the partial equation

- 4 = - 2 + c ⇒ c = - 4 + 2 = - 2

y = - \frac{2}{5} x - 2 ← equation of parallel line

Hope this helps!!
