The answer will be 2(x+3)
The slope would be 2. the equation to find slope is m= y2-y1/x2-x1 , so 0- -4 is 4, and 2-0 is 2, and 4/2 is 2.
Answer: (-2, -5)
Step-by-step explanation:
When reflecting over the y axis, (x, y) becomes (-x, y).
So A(2, -5) turns into (-2, -5).

Answer:
75 total tickets
Step-by-step explanation:
METHOD 1:
We know that 45 children's tickets have been sold, being 60% of the total tickets having been sold.
So, basically, we solve for x:
We have, 60% × x = 45
or, 60/100 × x = 45
Multiplying both sides by 100 and dividing both sides by 60,
we have x = 45 × 100/60
x = 75
If using calculator, enter 45x100/60, which will give you the answer.
------------------------
METHOD 2:
Division is the opposite of multiplication
Start with the formula to calculate the percentage of total
y=value÷ percentage/100
Substitute values in the equation
y=45÷60/100
Simplify and solve
y=45÷0.6
y=75
Both methods give you 75, therefore 75 tickets have been sold
