proportional relational ship  

y= kx

7 = k2

solve for k

7/2 =k


y = 7/2 x

if y = 21

21 =7/2 x

solve for x

multiply by 2/7 on each side

21* 2/7 = 2/7*7/2 x

6 =x

Solve (x-3)^2 =5 completing the square
otez555 [7]

Answer:

x = 3 ± √5

Step-by-step explanation:

The expression (x - 3)² = 5 doesn't need completing the square to solve (this is the step after you finish completing the square):

Step 1: Square root both sides

x - 3 = ±√5

Step 2: Add 3 to both sides

x = 3 ± √5 = 0.76392, 5.23607

Write and solve a real world problem in which the part of a whole results in a number greater than the whole itself.
daser333 [38]
I can think of one case like this: when the whole is negative.

for example, if your family has a debt of 200 dollars, this means that the family has -200 dollars.

Now, the family has four members. How much money does each of the member have?

and the way to solve is is this:

-200/4=-50.

so each person "has" -50 dollars, which is more than -200!
