No, the relation of hours of study time to grade earned on a test is not a function because there cannot be more than one output for one input. Also, the graph of the points doesn't pass the vertical line test.

Step-by-step explanation:

In order for something to be classified as a function, it needs to follow two rules:

1. There can only be one output for a certain input.

Although different inputs can have the same output, one input can't have more than one output. In this problem, the input 6 has two outputs: 75 and 82. So, the relation is not a function.

2. The graph of the points has to pass the vertical line test.

First, take the points from the table and graph them. These points are:

(4, 75), (6, 75), and (6, 82).

The vertical line test states that if a vertical line drawn on the graph intersects the graph more than once, then the graph isn't a function. In this case, a vertical line can be drawn at x = 6. This line ends up intersecting two points: (6, 75) and (6, 82). Since the vertical line intersected the graph at two points, the graph of the relation isn't a function.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
