The number of cars that have passed through the intersection is 245.
Direct variation is when two variables move in the same direction. If one variable increases, the other variable increases.
The equation that represents direct variation is; c = wk
Where:
1085 = k31
k = 1085 / 31
k = 35
c = 7 x 35
c = 245

Answer: x=sqrt10-2, x=-sqrt10-2
Step-by-step explanation: square root both sides of the equation.
x+2=sqrt10,-sqrt10
subtract 2 from both sides of the equation
x=sqrt10-2, -sqrt10-2
Answer:
raising both sides of the equation to a certain power in order to eliminate radicals may result in the creation of extraneous roots
Step-by-step explanation:
