Answer:
1. 25
2. 9
Step-by-step explanation:
If I'm correct, to complete the square you need to use
So, for #1, b is 10. = 5.
= 25.
For #2, b is -6. = -3.
= 9.
7x-2y-1= The x=3 The y is= 4

Slope =
Slope =
Now we write the equation.
y = mx + b
y = -3x + 9
In this equation -3 is the slope and 9 is the y-intercept.

Answer:
About 17 weeks
Step-by-step explanation:
Given
Ryan:
<em /><em> (weekly)</em>
Sarah:
(weekly)
Required
Determine the number of weeks they have the same cards
Represent the number of weeks with w:
For Both individuals, number of card at any given week is:
So,
For Ryan, the expression is:
For Sarah, the expression is:
To determine the number of weeks, we have to equate both equations:
Collect Like Terms
Solve for w
16.6 implies about 17 weeks, because 16.6 approximates to 17
<em>Conclusively, Ryan and Sarah will have the same number of balls in about 17 weeks</em>
