What is an equation of the line perpendicular to y=-2x-2 and through (-2,4)

Let and

We have

Therefore

We have the equation of a line:

Put the coordinates of the point (-2, 4) to the equation of a line:

     add 1 to both sides

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
