Find the value of $B - A$ if the graph of $Ax + By = 3$ passes through the point $(-7,2),$ and is parallel to the graph of $x + 3y = -5.$

Since B is equal to -9, then A must be equal to 3. "B - A" is equal to -12 The expression of the line is then:

Step-by-step explanation:

In order to solve this problem, lets first find the slope of the line. Since the line we want to know is parallel to "x + 3y = -5", then their slopes are the same, therefore:

The slope of the line is the number that multiplies "x", therefore m = . Organizing the first equation to the form we need, gives us:

We know that because the lines are parallel, if we apply the point given we will find the value of B and therefore the value of A.

Since B is equal to -9, then A must be equal to 3. "B - A" is equal to -12. The expression of the line is then:

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.
