Sur it's a function because for each x value corresponds one and only one y value.
Another easy way to determine if y is a function is to apply the vertical test:
If you draw a vertical line and this lines intersects the graph in one point, then y is a function
The best way to explain it is that 37 ÷ 6 is 6 remainder 1 so the answer is C) 6 1/6
B is the correct answer. Less than or equal to 35 t shirts orders.
$325 - $45 delivery charge for ALL orders, = $280.
$280 divided by $8 per order is 35 t shirts.
Following order of operations:
3^2 = 9
(10-2) = 8
Now you have :
9 + 8 x 5 -4
Multiplication is next:
9 + 40 -4
Now just add and subtract from left to right:
9 + 40 = 49
49-4 = 45
The answer is 45
