For Sami's skate
and 
For Brad's skate
and 
<u>The equations</u>
The equation is derived using: 
For Sami's skate
For Brad's skate
<u>When the cost are the same</u>
To do this, we equate both expressions
i.e.
i.e. the cost are the same at the 4th hour
<u>What is the cost</u>
Substitute 4 for x in any of the equations
<em>The cost is $14.00</em>
This is really simple. We know that landing a 6 is a 2/7 chance that means there is a 5/7 chance of NOT landing a 6 which means that the probability of landing a number that is not 6 would be 5/7. Your answer is D.) 5/7
Step-by-step explanation:
The length of a rectangle, l = 3 units
The breadth of a rectangle, b = 4 units
Nancy needs to increase both the length and the width of the rectangle by 2 units.
The area of a rectangle is given by
A = length(l) × breadth(b)
Here,
A = 3 × 4
= 12 unit²
If both length and width of the rectangle increase by 2 units,
New length = (4+2) = 6 units
New width = (3+2) = 5 units
New area = 6 × 5 = 30 unit²
Hence, new area becomes 30 unit².
Answer: One possible equation could be y = -2x^2 - 3.
The equation that is given would be in the shape of an upside down parabola. It would have a maximum (vertex) at (0, -3).
The point (0, -3) would also be the y-intercept of the graph.
You could change the -2 to any other negative number and the equation would work in your problem.
