What is the slope of the line parallel to the line 4y - 7x = -4?

The slope is  7/4 as well

Step-by-step explanation:

First convert the equation into slope intercept form  and to determine the slope.

4y - 7x = - 4      Add 7x to both sides

    +7x         +7x

4y =  7x  -4       Now divide both sides by 4  

y = 7/4x - 1       In this case the slope is 7/4  and the y-intercept is -1 .

Now notice that the slope of parallel lines have the same slope and different  y-intercepts. Meaning that the slope of this line will be same as the slope of the other line.

Step-by-step explanation:

The slope of the line parallel to the line given will be the same. Parallel lines NEVER tough and cross each other. Therefore, the slope will be the same.

               [add both sides by 7x]

                  [divide both sides by 4]

                      [*Remember, you are dividing both 7x and -4 by 4]

Therefore, the slope is .

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.
