Me with both of these questions i’m supper stuck

ONE SOLUTION

Step-by-step explanation:

When two points on a line are given, the equation of the line is given by the formula:

where and are the points on the line.

Here, the first set of points are: and .

Therefore, and .

The line passing through this is given by:

∴ 2x + y - 1 =0

Now, for the second line, the points are:

and .

Therefore,

∴ 2x - y + 2 = 0

Now, to determine the number of solutions the two equations have, we solve these two equations,

Adding Eqn(1) and Eqn(2) we get:

4x = -1

And .

Since, we arrive at unique values of 'x' and 'y', we say the lines have only one unique solution.

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.

ok
