Answer:
subtract the x from the other x and the y from the other y. Put that equation in a square root.
Answer:
x+3
Step-by-step explanation:
sqrt(x^2+6x+9)
factor
We know this is a perfect square trinomial
sqrt(( x+3)^2)
Taking the square root of a square
x+3
Answer:
y=8
Step-by-step explanation:
12(3+y)=5(2y+8)
⇒36+12y = 10y+40
⇒12y-10y=40-36
⇒2y=16
⇒y=8
Answer:
The answer is 9/4
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Given x and y are in proportion then the equation relating them is
y = kx ← k is the constant of proportion
To find k use an ordered pair from the table
Using (2, 10 ), then
10 = 2k ( divide both sides by 2 )
5 = k , thus
y = 5x ← relationship between x and y
